Test Bank For CompTIA Network+ Guide to Networks 10th Edition 2025 by Jill West Chapter 1-12 Chapter 01 Introduction to Networking 1. Hennessy is studying for the Network+ certification exam. The question asked is, "What is the definition of a

network?" How does Hennessy answer? a. A network is a group of devices. b. A network is a group of computers and other devices (such as printers) that are connected by some

type of transmission media. c. A network is comprised of the wiring that flows throughout an office space or building. d. A network is computer hardware working together.

ANSWER: RATIONALE:

b

Loosely defined, a network is a group of computers and other devices (such as printers) that are connected by some type of transmission media. In order for a group of computers to be considered a network, the device's hardware and software must work with a transmission media to allow data to be sent and received between each device. A network can be as small as a computer hooked up to the Internet or as big as the Internet itself.

(P2P) networking architecture to a client-server architecture. The company has grown to 30 users, so why is it better for her to use a client-server architecture over peer-to-peer? Choose all that apply. a. Client-server users can sign on to the network from any computer and get access to the resources that

Active Directory allows. This process is managed by AD DS (Active Directory Domain Services).

Sharing files on a peer-to-peer network means creating 30 user accounts to share documents and then set up each workstation with the same user accounts. b. In a client-server network, an administrator can ensure only authorized users can access the network. c. In a client-server network, an administrator can control what files a user can open, read, or edit. d. In a client-server network, servers only need as much memory as the clients since their workload is the same.

ANSWER: RATIONALE:

a, b, c

In a client-server network, users can log in from any computer that's connected to the network and gain access to the resources that Active Directory permits. The process is managed by AD DS (Active Directory Domain Services). With the help of an administrator, only authorized users can access the network. Moreover, the administrator can control which files a user can open, read, or edit.

she makes a transaction, she looks at the top left of her browser's navigation bar and sees that the website is using HTTP and not HTTPS. What should Kathrine do? a. Continue with her transaction; it doesn't matter if the website is secure as she has virus protection. b. Try another browser to see if the website is secure through the other browser. c. Leave the website since HTTPS is not secure. d. Call her bank to complain about the website.

ANSWER: RATIONALE:

c

It is important for a website to have a secure connection using HTTP layered on top of an encryption protocol such as SSL (Secure Sockets Layer) or TLS (Transport Layer Security). This creates HTTPS (HTTP Secure), which ensures that all data sent between the website and user is encrypted and cannot be accessed by unauthorized parties. If a website is not encrypted with HTTPS, it is highly recommended to leave the site immediately as the data shared between the website and user can be easily accessed by others. Therefore, if HTTPS is not used to encrypt the bank's website, Katherine should leave the site immediately to prevent others from accessing her sensitive data.

following question, "What are the primary transport layer protocols, and what is their function in transporting application layer payloads from one application to another?" How does Melanie answer? Choose all that apply. a. SNMP (Simple Network Management Protocol) programs, which monitor and gather information

about network traffic and can alert network administrators about adverse conditions that need attention. b. TCP (Transmission Control Protocol) is a connection-oriented protocol used by apps like web browsers and email. It ensures data delivery by making a connection with the end host, checking if the data is received, and resending it if required. c. The principal protocol is the IP (Internet Protocol). IP adds its own network layer header to the segment or datagram. d. UDP (User Datagram Protocol) is a connectionless protocol that doesn't guarantee delivery and is used for broadcasting, streaming video/audio over the web, and monitoring network traffic where guaranteed delivery is not as important as fast transmission. UDP is called a connectionless protocol or best-effort protocol and is also referred to as the fire-and-forget protocol.

The transport layer has two main protocols: TCP and UDP. They help transfer data between different applications. TCP (Transmission Control Protocol) creates a connection with the host, checks whether data has been received and resends it if needed. This makes TCP a connection-oriented protocol. TCP is used for applications such as web browsing and email. It takes longer, but it's important for data to arrive safely. UDP (User Datagram Protocol) on the other hand does not guarantee delivery because it doesn't maintain a connection to check whether data has been received. UDP is, therefore, called a connectionless protocol or besteffort protocol. UDP is used for broadcasting, such as streaming video or audio over the web, where speed is more important than guaranteed delivery. It's also used to track network traffic.

Room level: This system incorporates a sprinkler or gas system with at least two detection points to activate the system, which provides fire suppression in parts of a room or throughout the entire room. Instead of water, data centers often use a foaming agent or gas suppression agent that decreases oxygen levels to suffocate a fire or absorb heat, which suppresses the fire without damaging sensitive electronics. For example, the popular FM-200 system combines carbon, fluorine, and hydrogen to absorb heat without leaving a residue and without generating any toxic fumes.

Establishing a plan for resolving the problem. When dealing with network problems, it is important to establish a plan for resolving the issue. Changes to a network can potentially disrupt a lot of people's work. Therefore, before implementing a fix, it is crucial to consider the scope of your change and how it will affect users, their applications, and their data. If the problem is not urgent, it is best to make changes when the least number of users are on the network. In many cases, specific change management procedures must be followed to implement a change. Change management includes well-defined processes that evaluate the need for a change, the cost of the change, a plan for implementing the change with minimal disruption, and a backup plan in case the change does not work as expected.

the user traveled with the laptop, the system would randomly crash and get a blue screen of death (BSOD), and occasionally the system became unstable or would sometimes lose data. This only happened when the laptop was traveling, such as in an airplane, or was just taken out of luggage after traveling. When the laptop was at the office, everything was fine. After the user explained the symptoms to Rayco, he believed he knew most likely what the problem was. So, he took apart the laptop and checked the memory modules. One of the chips was not all the way pressed into its slot. So, he pushed the chip back in its slot and checked the other chips; everything else was fine. Rayco then put the machine back together. What would be a good way for Rayco to test the laptop to see if he can get the same errors to happen again? a. Hand it back to the user and tell her it's fixed, and they can take it on their next trip. b. Handle it like you would if you were on a trip.

The network equipment room is called the TR (telecommunications room), TE (telecommunications enclosure), or data closet; a data room is an enclosed space that holds network equipment. These spaces might require size, clearance around equipment, wall materials, and physical security (such as a locked door). Larger data rooms (also called TR) and smaller data closets (also called TE) require good cooling and ventilation systems to maintain a constant temperature.

It's impractical to install a separate console for every device on a rack. Typically, racks have one or more KVM (keyboard, video, and mouse) switches, which connect to a single console to provide a central control portal for all devices on the rack. In fact, a KVM switch can be used to control multiple servers across different server racks.

she needs to address before executing the installation. One of the main issues is deciding whether to use multimode or single-mode fiber. If she considers price, multimode would be the cheaper option. However, if she wants to cover a longer distance, single-mode fiber would be the best choice. Warda's campus is extensive, so it requires a long distance to be covered. Moreover, there has been a significant increase in data traffic since the addition of new programs like robotics, ethical hacking, and networking to the curriculum. Lastly, legacy systems are still in place, which is an important factor to consider when deciding which product to use. Which option do you think Warda should choose, and why? a. Warda should opt for single-mode fiber since it offers a higher bandwidth despite the fact that it has a

higher cost per foot to install. Over time, Warda will recover the cost as single-mode fiber is easy to maintain and can handle higher data rates as more programs come online. b. Warda should opt for multimode fiber since there are some existing legacy systems in place.

Choosing this option would mean that only the cable would need to be upgraded without having to replace the legacy systems, which would otherwise increase the project cost. Although there may be some signal fade issues with multimode fiber over long distances, a signal booster can be used to address this, and the installation process is relatively simple compared to single-mode fiber installation. c. Warda should opt for single-mode fiber since it is durable and will last much longer than multimode fiber. While the cost is higher, since it lasts longer, the cost for the installation will be reduced over time. d. Warda should choose the multimode fiber because it has a longer lifespan and is versatile so that it can be operated with either colored LEDs or laser light depending on the desired data transfer speed.

ANSWER: RATIONALE:

b

Warda should opt for multimode fiber since there are some legacy systems in place. Choosing this option would mean that only the cable would need to be upgraded without having to replace the legacy systems, which would otherwise increase the project cost.

He promotes the company's fast Internet speeds of up to 50 GB per second. Telco also guarantees high availability with 99.999% uptime, which means there will only be 26 seconds of downtime per month. Telco offers a personal account representative who is available 24/7 to handle any problems that may arise. If a customer is not satisfied with the service, they can cancel their contract within the first 30 days at no charge or after 30 days with a 60-day notice and a $1000 cancellation fee. Of course, Francisco is giving a sales pitch; once a company decides they want Telco's services, then they will want, in plain language and in measurable terms, the aspects of the services provided to them, contract duration (minimum or maximum), guaranteed uptime, options for compensation if outages exceed defined thresholds, problem management, performance benchmarks, and termination options.

Georgy asked his supervisor about the reason, the supervisor explained that it is because the advertised mean time between failures rate of that particular brand is usually very reliable. Why is the reliability of the advertised mean time between failures rate important? Choose all that apply. a. Giving devices an MTBF (mean time between failures) allows technicians and others with fiduciary

responsibility to determine if a device is a worthwhile investment because of how often it might need replacement. b. MTBF considers the time required to repair a failed system or component. If the repair time is significant, it can greatly impact the overall downtime experienced by the system. c. While any single device might experience a failure much sooner or later, vendors and technicians budget for repairs or replacement of devices based on the advertised MTBF. d. MTBF assumes a constant failure rate over time, which holds true for all systems.

ANSWER: RATIONALE:

a, c

Devices on a network typically have a calculated MTBF (mean time between failures). This is the average amount of time that will pass, of devices of the same make and model, before the next failure is expected to occur. While any single device might experience a failure much sooner or later, vendors and technicians budget for repairs or replacement of devices based on the advertised MTBF.

A single point of failure (SPoF) refers to a component or part of a system whose failure would cause the entire system to malfunction or catastrophic system failure. Essentially, it's a critical element within a system where the failure of that one component would result in a cascading failure throughout the system, leading to downtime, reduced performance, or even complete system failure. To maximize availability, you should ensure that critical network elements, such as your connection to the Internet, your file server's hard disk, and your power are redundant.

oversees network operations, which include managing servers, routers, and everything in between. To ensure that these devices function properly, Jai and his team make sure that each mission-critical hardware device has at least one duplicate critical component, such as a NIC, fan, or processor. Then, if a component fails, another one will take over without any loss of connectivity. What is this an example of? a. redundancy b. hot-swappable c. automatic failover d. fault tolerance ANSWER: RATIONALE:

c

To achieve the utmost fault tolerance, each critical device requires redundant NICs, power supplies, cooling fans, and processors. All of these should, ideally, be able to immediately assume the duties of a failed component, a capability known as automatic failover. If one NIC in a router fails, for example, automatic failover ensures that the router's other NIC can automatically handle the first NIC's responsibilities.

(QoS) policies to ensure that VoIP applications receive sufficient bandwidth and low latency. However, over time, the routers receive firmware updates and patches that modify some settings. On another occasion, another network administrator makes manual adjustments to some QoS settings on one router but does not update the central configuration management system. Eventually, a router fails and is replaced with a different model of router. Finally, a junior network technician mistakenly makes changes to the QoS settings on one of the routers while attempting to perform a maintenance task. As a result, over time, the VoIP applications for which the original network administrator designed and implemented the QoS policies are not working properly. Calls are being dropped, and the lines begin to get staticky when there are a lot of phone calls coming in simultaneously.

One of the laptop's OEM management software systems had recently notified Allan about the availability of a new BIOS update that needed to be installed. The first step was to save a copy of the old BIOS, and then the ROM was flashed with the new BIOS firmware. However, after installing the new BIOS firmware, the laptop would not turn off automatically, so the old BIOS firmware had to be reflashed. The problem was that there were 10 laptops of the same make and model in the office, all of which needed a firmware update, according to the OEM management software. Now, Allan was facing a risk. Should he update the firmware of the remaining laptops and hope the same problem doesn't occur? Or should he disable BIOS updates for all the affected laptops to prevent this problem from happening altogether? a. Shut off BIOS updates for all of the laptops. b. Take three laptops (30%) at random and see if they have the same problem. If they don't, continue

with the updates for all the laptops. If they do, stop updates for all the laptops. c. Ignore the issue and hope the next firmware update will fix the problem. d. Since there are only 10 laptops, shut off BIOS updates for the ones with the issue and continue to update for the rest of the laptops.

Thus, he decides to define a specific range of IP addresses for the router to use. What is the defined range of IP addresses called? Choose all that apply. a. DHCP reservation b. DHCP scope c. DHCP lease d. DHCP pool ANSWER: RATIONALE:

b, d

POINTS: QUESTION TYPE: HAS VARIABLES: LEARNING OBJECTIVES:

1 Multiple Response False WEST.NET+.25.3.2 - Configure TCP/IP settings on a computer, including IP address, subnet mask, default gateway, and DNS servers.

Pacheco will define a range of IP addresses for his network, called a DHCP scope or DHCP pool, to be assigned to clients when they request an address.

unable to print. They receive an error message indicating that the printer cannot be found. How can Landers prevent this issue from occurring in the future? a. Landers should try a different printer. b. Landers should hardwire (USB connection) a printer to each computer and avoid the issue altogether. c. Landers should use a persistent or static IP address. d. Landers should check for issues with his DHCP server.

ANSWER: RATIONALE:

c

Landers should use a persistent or static IP address for all printers. This will ensure that printer applications always locate the printer without any issues.

Typically, IP addresses are leased from the DHCP server for a fixed duration of time. However, by using a static IP address, the DHCP server will not change it, providing a more reliable connection.

The default gateway is wrong. b. There is no default gateway added. c. The router has the wrong network settings. d. The subnet mask is not correct for this network.

ANSWER: RATIONALE:

d

POINTS:

1

When devices on a network have different subnet masks, there are communication issues. This is because they may not agree on which addresses are part of the local network and which are remote. Such disagreements can result in certain devices being unreachable or communication being misrouted.

Today, Windows Server is capable of more nuanced configuration, called splitbrain or split-horizon deployment, to handle these two populations differently. For example, consider a fictional website, careers.example.com, that lists internal job postings for employees and different job postings and information posted to the public. DNS policies differentiate between internal and external clients, sending their requests for name resolution on the same FQDN to different IP addresses, and, therefore, different information on the website.

Garrett should consider increasing the size of his DHCP pool; given that he is using a class C address scheme, he may want to consider switching to CIDR. Additionally, it seems that his leases may be set too long, as not all 230 people are online or in the office at the same time. It might make more sense to set DHCP leases to last only four to eight hours, so that leases are renewed each workday instead of for a longer period.

Application layer protocols can collaborate with UDP to emulate some of the reliability normally provided by TCP. For example, RTP (Real-time Transport Protocol), which is used to transmit audio and video on the web, operates at the application layer of the OSI model and relies on UDP at the transport layer.

9. Jeremy was sitting in the network operations center (NOC) watching a live stream from the president of his

company. As he was watching the feed, he noticed that the picture was a little "glitchy," occasionally patches of color would be missing from the feed. There was nothing he could do about it because of the way the feed was being transmitted. What protocol could the feed be transmitting in, and why would it look like there were errors in the feed? a. IP. It specifies where data should be delivered, identifying the data's source and destination IP

addresses, but it only provides error checking, not a correction mechanism. Not having a correction mechanism caused the packet loss. b. TCP. It provides error checking and correction mechanisms, but data streams are too big not to have any problems during broadcasting. The large size of the data stream caused the packet loss. c. UDP. It does not provide error checking or correction mechanisms, so if a packet is lost or corrupted during transmission, it will not be retransmitted, which is why the image had data packets dropping out of it. d. HTTP. Jeremy had no control over how the live feed came in, and it switched between multiple protocols including HTTP. The switching between protocols caused the packet loss.

ANSWER: RATIONALE:

c

In User Datagram Protocol (UDP), each message, known as a datagram, is treated independently, and there is no built-in mechanism to ensure that they arrive in the same order that they were sent or if they arrive at all. Additionally, UDP does not provide error checking or correction mechanisms, so if a packet is lost or corrupted during transmission, it will not be retransmitted, and it's up to the application layer to handle any errors or issues. The packet loss is what causes pieces of the video and/or audio to drop out.

What is this a function of? a. symmetric encryption b. asymmetric encryption c. authentication encryption d. AES encryption ANSWER: RATIONALE:

b

Asymmetric encryption protocols exist between Danika's computer and the bank's servers. The bank's server holds the public key, while Danika's browser holds the private key. In case Danika logs in from a different computer or browser, the private key is not the same. Hence, the bank's servers need to verify whether it is indeed Danika who has used her credentials to log in to the bank's website.

22. Axel is the network administrator for a mid-sized company that has offices on five nonconsecutive floors in

a 50-story building. The company is located on floors 30, 35, 36, 40, and 41, and each floor has a "telecom closet" where all of the switches and routers are located. However, the "telecom closets" on floors 30 and 41 are th vacant. The company also has an actual server room situated on the 35 floor. Lately, Axel has been receiving th st st complaints about data errors from the 30 and 41 floors. On the 41 floor, Wi-Fi users have noticed their signal strength dropping to almost zero, and their network connections frequently drop. They must resend th emails because they fail to send the first time. On the 30 floor, file transfers slow down significantly and sometimes time out. Additionally, employees experience a lot of jitter in the signal when they are streaming live presentations. How can Axel resolve this situation? a. add 1 router b. add 2 hubs c. add 1 repeater d. add 2 repeaters ANSWER: RATIONALE:

d

To compensate, Axel needs to boost the signals en route using two repeaters, one for the 30th floor and one for the 41st floor. The repeaters will regenerate a digital signal in its original form without the noise it might have previously accumulated and caused the issues that Axel had on those two floors.

with the exiting cable installation. He had some connectors left over from the last installation and ordered new cable. The cable was installed properly, However, after completing the installation, the jitter worsened, and employees were unable to host or participate in video meetings. How could Billie have avoided this situation? a. The connectors should have been double checked first. b. The cable run should have been checked for kinks. c. The connectors should have been specific to the cable. d. The wrong cable was installed.

ANSWER: RATIONALE:

c

When sourcing connectors for coaxial cable, Billie should have specified the type of cable he needed. For instance, since he had F-type connectors, he should have made sure that he had RG-6 coax, and that F-type connectors were made specifically for RG-6 cables. That way, the connectors and cable shared the same impedance rating. If impedance ratings do not match, data errors will occur, and transmission performance will suffer.

bandwidths and longest distances (without requiring repeaters) of all wired network transmission media? a. MMF (multimode fiber) b. duplex mode fiber c. SMF (single mode fiber) d. simplex mode fiber ANSWER: RATIONALE:

c

SMF (single mode fiber) consists of a narrow core of 8 to 10 microns in diameter.

Laser-generated light travels a single path over the core, reflecting very little.

Because it reflects little, the light does not disperse as the signal travels along the fiber. This continuity allows SMF to accommodate the highest bandwidths and longest distances (without requiring repeaters) of all wired network transmission media.

In troubleshooting a physical layer problem, the cause of a problem might be found by simply testing a cable's continuity (cable continuity tester)-that is, whether it is carrying a signal to its destination. As an example, two pairs are reversed with each other when they shouldn't be. For example, perhaps the wires of the green pair starting at pins 3 and 6 are inserted where the wires of the blue pair should go at pins 4 and 5, and vice versa.

There could be two possible reasons why Jenine is unable to connect to the Wi-Fi. First, the channel selection needs to be set to auto on all devices. If it's not, then it's possible that the access point is on the wrong channel. Second, it's possible that the password that Jenine is using to connect is incorrect. If the password is incorrect, then the access point will not connect. Since this is a home network, it's unlikely that the coverage area is too large for the access points to connect to the router.

This is called the hidden node problem, where a node is not visible to other nodes on the other side of the coverage area. Nodes that are physically located far apart from each other on a wireless network present a particular challenge to avoiding collisions because they are too far apart to detect each other's transmissions to a central AP. As employees moved into the office they moved farther away, and the nodes became less visible to each other, causing the increase in packet collisions.

There are two types of authentication offered by WEP, and they are no longer considered secure. The first is Open System Authentication (OSA), where no key is used at all. In this method, the wireless access client only needs to know the access point's SSID to request authentication. The second is Shared Key Authentication (SKA), where all wireless access clients use the same key (or one of a few keys), which can then be used to encrypt transmissions.

and the protocol was introduced in 2018, so his router should have it. However, when he tries to turn it on through the router's web interface, he can't find the setting. What could be the reason that WPA3 is not available on Marcelo's router? Choose all that apply. a. His router is defective. b. The router is WPA3 compatible, but the firmware has not been updated. c. The mandate to make all routers WPA3 compatible did not apply to the router that Marcelo

purchased. d. He is searching in the wrong location in the router settings.

ANSWER: RATIONALE:

b, c

It is possible that Marcelo's router is compatible with WPA3, but it may require a firmware update to function correctly. Manufacturers often take time to release firmware and software updates after a product launch. Another reason why the product that Marcelo purchased may not be WPA3 compatible is that it may have been built and shelved before the mandate was in effect.

Authentication is the sign-in process that allows an entity (such as a user, device, or application) to connect to a resource such as a network if they provide the correct credentials, such as username and password. Authorization determines what the entity can do once it gets into the resource. For example, any employee might be allowed to sign into the network (authentication), but only an administrator has permission to edit user accounts (authorization).

Wi-Fi networks can be vulnerable to various security threats such as war driving, evil twin attacks, WPS attacks, and brute force attacks. WPS or Wi-Fi Protected Setup is a feature created to simplify the process of connecting devices to a secure Wi-Fi network. It does this by allowing the use of a push button on the router or a pin number provided by the manufacturer, instead of having to enter a long passphrase. However, this convenience comes at the cost of security. Using the push button mode or pin number method makes the device to network connection less secure and creates an entry point for hackers. Therefore, it's important to be aware of these security threats and take necessary measures to prevent them in order to protect your Wi-Fi networks.

A Wi-Fi analyzer is a tool that scans the frequencies used by Wi-Fi networks in a particular area. It listens for beacon frames and other management frames sent by Wi-Fi access points. Once it detects a Wi-Fi network, it measures the signal strength of the network. This measurement helps to determine the strength or weakness of the signal at a particular location. Wi-Fi analyzers are also useful in detecting which channels are being used by nearby networks. This information is crucial in selecting the least congested channel for optimal Wi-Fi performance.

a, b, c

There are a few common reasons why a Wi-Fi client may not be able to connect to an Access Point (AP). This situation could be due to the wrong SSID being selected by the wireless client. In order to connect, the correct SSID must be selected. There could be an encryption protocol mismatch. This means that the wireless client must be configured to support the same encryption protocols offered by the access point. If this is not the case, the client will not be able to connect. An incorrect passphrase or security key could be the issue. If the passphrase or key does not match that of the access point, the client will not be authenticated and will be unable to connect.

whenever he enters the garage from the street or is parked outside his unit, he can easily log in to his home network. He is concerned about the security of his network and wants to know how he can prevent any unauthorized access from outside the apartment or from within the underground garage. How can Vasyl fix this issue? Choose all that apply. a. put carpets on the floor to absorb the signal b. lower the power levels on the router c. move APs away from exterior walls d. put tinfoil around the back of the router to keep the signal from propagating ANSWER: RATIONALE:

b, c

Most routers come with their power settings set to 100%. Therefore, Vasyl should adjust the power settings until the signal can no longer reach the outside. He might have to move the router to a higher position and decrease the power by 50% or more. If Vasyl has access points installed around his apartment, he should ensure that they are not located near windows or walls that face outside. Placing them closer to the center of the apartment will also help to reduce signal leakage to the outside.

15. A key factor in maintaining the availability of network resources is fault tolerance. What is fault tolerance?

Choose all that apply. a. the process of intentionally introducing errors into the network to test its resilience and identify

potential vulnerabilities b. the ability of a network to automatically redirect traffic to alternative routes in case of congestion or slowdown, ensuring continuous operation c. the capacity of a system to continue performing despite an unexpected hardware or software malfunction d. the process of duplicating critical network components, such as servers or storage devices, to ensure redundancy and minimize the risk of data loss ANSWER: RATIONALE:

c, d

Maintaining the availability of network resources is crucial, and fault tolerance plays a vital role in achieving it. Fault tolerance refers to the system's capacity to continue functioning, even in the event of unexpected hardware or software malfunction. One of the key aspects of network design that contributes to fault tolerance is the provision of multiple paths for data to travel from one point to another. This may involve duplicating essential network components such as servers or storage devices to ensure redundancy and minimize the risk of data loss. Thus, if one connection or component fails, data can be rerouted via an alternate path.

launched a website that is managed by racks of servers. These servers are responsible for a variety of tasks, including taking orders, processing payments, issuing refunds, and updating the website's content on a daily basis. When a client types in the website URL, they are directed to the website. From the client's perspective, it appears that the website is powered by a single server. However, in reality, there are multiple servers working together to ensure that the website functions smoothly. How does this process happen? Choose all that apply. a. the client gets to choose which server they work with b. web client directs request to a single VIP (virtual IP address) c. racks of servers are clustered to look like one server d. load balancing directs traffic evenly between the servers ANSWER: RATIONALE:

b, c, d

POINTS: QUESTION TYPE: HAS VARIABLES:

1 Multiple Response False

To access the website, web clients direct requests to a single VIP (virtual IP address) that represents the entire cluster. To the client, the cluster looks like a single web server. On the back end, though, a load balancer directs traffic evenly between the web servers, and the servers have access to all the data needed to respond to any webpage requests from clients (such as website files, databases, and authentication services). The clients, however, are not aware that two physical machines are at work. As far as a client is concerned, it's talking with a single server.

b

When operating in host-only mode, virtual machines (VMs) on a single host can share data with each other and with their host, but they cannot communicate with any external nodes beyond the host. In other words, the virtual network interface cards (vNICs) never receive or transmit data via the physical network interface card (NIC) of the host machine. Another advantage of creating a virtual network in host-only mode is that all of the operating systems can be on a single computer, instead of multiple computers, and the single machine can be isolated in any location.

It is possible for Angela to use a type 2 hypervisor. However, it is important that the host machine has enough resources available to use. Every virtual machine uses a portion of the host OS and hardware resources. As the number of guest machines increases, the resources available for the host decrease until, eventually, the host can no longer function properly. Additionally, not all hypervisors support every operating system. To avoid issues, it is recommended to refer to the help documentation for the hypervisor that you plan on using before downloading.

d

The subnet mask 255.255.255.240 can create 16 subnets. Here is how it works: In binary, the subnet mask looks like this: 11111111.11111111.11111111.11110000.

By borrowing 4 bits from the last octet (in red), the last octet becomes 240. The n four red 1s are used to create the subnets. Using the formula 2 , where n equals 4 the number of bits taken from the last octet (which is 4), then 2 = 16. This means that 16 subnets can be created. In order to create subnets, all bits must be borrowed from left to right. So if two subnets are needed and the last octet is 1 .00000000, it would look like this 2 = 2 .10000000. For four subnets, 2 bits 2 would be borrowed or 2 = 4 .11000000, and so on.

about to add at least two VLANs due to expansion. Howard, who is new to VLANs, asked his IT manager which type of VLANs pose the greatest security risk. Which VLANs did the IT manager pick? Choose all that apply. a. Data VLAN b. Native VLAN c. Voice VLAN d. Management VLAN ANSWER: RATIONALE:

b, d

There are two VLANs that pose security risks: the Native VLAN, which receives all untagged frames from untagged ports. By default, this is the same as the default VLAN. However, this configuration poses a security risk when untagged traffic can travel in a VLAN-managed network. The Management VLAN can be used to provide administrative access to a switch. By default, this might be the same as the default VLAN; however, this arrangement poses a security risk and should be changed.

Internet alongside Zoom. She purchased the high-speed package from her cable TV provider, which offered her 500 Mbps download speed and 20 Mbps upload speed. She made sure that her equipment was up-to-date to handle the speed increase. After the modem was installed, she downloaded a software program called Speedtest to confirm that she was getting the speed she was paying for. She tested her connection at different times during the day and discovered that the download speeds she was getting were not always what she paid for. Some days, she would get over 550 Mbps download, while on others she would only get 200 Mbps download. Occasionally, her speed would drop below 100 Mbps, although her upload speed remained between 18 and 20 Mbps. She contacted her carrier to ask about the issue and was told that she was getting the service she paid for. Why are Alexis' speeds fluctuating so much? a. The network interface card (NIC) in her computer couldn't handle that speed. b. There was a problem on Alexis' side of the demarc. c. It was the "best effort" by the ISP. d. There was a problem on the ISP's side of the demarc.

to issues with his edge routers. The technician from the IT firm told Byron that they have the same type of router and that Byron needs to update the firmware to get rid of the problem. The odd thing was that the IT technician referred to his router as an "exterior router" and not an "edge router." Why is that? a. Byron was using the wrong router. b. The technician misspoke. c. An edge router and exterior router can be the same. d. Edge routers and exterior routers look identical but are different.

ANSWER: RATIONALE:

c

Sometimes, a technician might refer to their own edge router as an exterior router because it communicates with routers outside the AS (Autonomous System). An Autonomous System is a collection of IP networks and routers under the control of a single organization that presents a common routing policy to the Internet. But keep in mind, every router communicating over the Internet is a trusted edge router for some organization's AS, even if that organization is a large Page 210

now needs to establish some Access Control List (ACL) rules for it. These rules will involve filtering traffic from the web server that is destined for the Internet. Why does Eduardo need to block this outbound traffic from his web server? a. to stop bad actors from starting a DoS attack b. to stop employees from accessing shopping sites c. to stop employees from accessing FTP sites d. to stop worms from spreading ANSWER: RATIONALE:

d

One reason to block Internet-bound traffic is to prevent the spread of worms. For instance, when operating a web server, which usually only needs to respond to incoming requests and does not need to initiate outgoing requests, a packetfiltering firewall can be set up to block specific types of outgoing transmissions initiated by the web server. This can help prevent the spread of worms that are created to infect web servers and spread to other computers on the Internet.

d

In certain cases, asymmetrical routing can lead to problems for NAT and firewalls that need to monitor traffic in both directions of a conversation to apply filtering rules correctly. Firewalls typically depend on TCP sessions to allow outgoing traffic in response to approved incoming traffic. If incoming traffic reaches a different firewall than the one a server is supposed to use for its outgoing messages, the firewall might mistakenly reject outgoing traffic that should have been allowed. With NAT, if the connection path changes due to routing issues, the Page 221

DDoS attacks are orchestrated through many sources. Most of these machines are zombies, which means the owners are unaware that their computers are being used in the coordinated attack. A type of malware called a bot is installed on each machine and gives the bot herder, or central controller, remote control of the computer. Computers and even IoT devices can be requisitioned as part of a botnet, also called a zombie army, in coordinated DDoS attacks without the owners' knowledge or consent. These botnets are sometimes made available for hire on the black market.

DRDoS (distributed reflection DoS) attack is a type of DDoS attack that is bounced off uninfected computers, called reflectors, before being directed at the target. This is achieved by spoofing the source IP address in the attack to make it look like all the requests for response are being sent by the target. As a result, all the reflectors send their responses to the target, thereby flooding the target with traffic.

The withdrawal occurred 3 minutes after she left the ATM, and it was the maximum daily limit of $2,000, which included the $500 she withdrew. There was no one near her when she made the transaction, so how could that money have been withdrawn? a. Brenda forgot about a $1,500 debit that had not cleared yet. b. This was an inside job. c. Someone used binoculars. d. Someone used a camera and card skimmer.

d

A camera and card skimmer are sure signs of shoulder surfing, although it may be hard to tell if this is happening. If Brenda had noticed the flyer holder taped to the ATM, she would have seen where the Wi-Fi camera was hidden. The skimmer is hidden in plain sight in that it is attached to where Brenda slid her card into the slot. That is where her card was read, and the camera caught her PIN. There was someone in the parking lot that was watching from the Wi-Fi camera to write down or record the PIN information. The rule of thumb for ATMs is, if something does not look right, yank on it. If it comes off, it was fake.

Using NIPS and HIPS together increases the network's security. For example, an HIPS running on a file server might accept a hacker's attempt to log on if the hacker is posing as a legitimate client. With the proper NIPS, however, such a hacker would likely never get to the server. Like an IDS, an IPS requires careful configuration to avoid an abundance of false alarms or a lack of needed alarms.

31. In today's increasingly connected world, the threat of firmware attacks is on the rise, emphasizing the critical

need to keep device firmware updated. However, even firmware updates can introduce issues that lead to computer malfunctions. Recently, an IT technician was prompted by the computer manufacturer to install a BIOS (Basic Input/Output System) firmware update. Sensibly, the technician created a backup of the old BIOS before proceeding with the update. Once installed, the computer functioned well but encountered an issue when shutting down-requiring the on/off button to be held for 10 seconds. Reverting to the old BIOS resolved the issue, until a new BIOS update was released two months later, resulting in the same problem. What course of action should the technician take now? a. block firmware updates b. call customer support c. continue trying when new updates are published d. do nothing ANSWER: RATIONALE:

a

Since this issue happened twice with two consecutive firmware updates, it might be best to shut off the firmware update feature on the device. If two separate firmware updates in a row fail, chances are there will not be any updates that will work.

Securing the network's gateways, where the Internet connects with the interior network, is considered network-based. It provides a formidable layer of defense against the primary source of intrusion-the Internet. However, this does nothing to prevent users from putting the network at risk with infected files on flash drives, laptops, or smartphones, and it cannot respond to problems that manage to wiggle through the edge defenses. Network-based firewalls and defenses must be implemented throughout the network, not just on the perimeter.

ANSWER: RATIONALE:

a, b, d, e

To continue using SNMPv2, Jenny needs to take the following actions: Disable SNMP on devices where it's not needed (1). Limit approved sources of SNMP messages (2). Require read-only mode so devices can't be reconfigured using SNMP messages (3). Configure strong passwords, called community strings, on SNMP managed devices. Use different community strings on different types of devices so that devices with less secure protections will not compromise devices with higher security (4).

Bandwidth management involves various technologies such as flow control, congestion control, and quality of service (QoS). Flow control configures interfaces and protocols to balance permitted traffic volume with a device's capability of handling that traffic. Congestion control adjusts the way network devices respond to indications of network performance issues caused by traffic congestion, so they don't make the problem worse. QoS prioritizes some traffic over other traffic, so the most important traffic gets through even during times of congestion.

in a different town. Before the relocation, Jasmine researched the town's weather patterns, annual flooding forecasts, and the electricity provider for the area. Her findings indicated a higher likelihood of power outages during winter, frequent power spikes, and a few incidents of fires due to electrical issues. Jasmine now needs to decide on the best type of UPS to purchase for her network. What type of UPS would be most suitable for Jasmine to consider? a. online UPS b. line conditioning UPS c. standby UPS d. offline UPS ANSWER: RATIONALE:

a

Jasmine should choose the online UPS. It uses the AC power from the wall outlet to continuously charge its battery while providing power to a network device through its battery. In other words, a server connected to an online UPS always relies on the UPS battery for its electricity. Because the server never needs to switch from the wall outlet's power to the UPS's battery power, there is no risk of briefly losing service. Also, because the UPS always provides power, it can handle noise, surges, and sags before these fluctuations reach the attached device.

affect company decisions? Choose all that apply. a. MAO (Maximum Acceptable Outage) b. RTO (recovery time objective) c. MTPD (Maximum Tolerable Period of Disruption) d. RPO (recovery point objective) ANSWER: RATIONALE:

b, d

POINTS: QUESTION TYPE: HAS VARIABLES:

1 Multiple Response False

The RTO (recovery time objective) defines the maximum tolerable length of time that a network can be down before operations are restored. It indicates when full functionality will be regained in the future, minus any lost data. Conversely, RPO (recovery point objective) defines the amount of historical data that needs to be restored from backups in the event of an outage. It represents the acceptable amount of data loss and shows the point in the past from which data will be recovered.
