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:

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.

a, c, d

Client-server architecture provides several advantages to network management. First, user accounts and passwords can be assigned in a centralized location. Second, access to shared resources such as data files or printers, can be centrally granted to individual users or groups of users. Third, network issues can be monitored, diagnosed, and often resolved from one location. This eliminates the need for administrators to go from workstation to workstation.

Since her company is growing, she wants to switch from a peer-to-peer

(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.

Katherine goes to her banking website to transfer money between her checking and savings accounts. Before

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:

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.

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. Page 14

b, d

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.

The question asked was "At what level to you find gas suppression systems?" How did Adrian answer? a. building level b. room level c. rack level d. ground level ANSWER: RATIONALE:

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.

a. Implement the solution or escalate the problem. b. Establish a plan for resolving the problem. c. Document findings, actions, and outcomes. d. Test your theory to determine the cause. ANSWER: RATIONALE:

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.

There seemed to be a memory chip issue. Sometimes, while

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. Roll it over different terrain in a suitcase for a couple

of days, put it in and take it out of the car, and then check it again for errors by using the onboard diagnostic utilities. c. Roll it around in luggage for an hour or two and maybe into the parking lot and then check it for errors. d. Shake it vigorously for a few minutes to see if that dislodges the memory chips. ANSWER: RATIONALE:

As a technician, Rayco should do everything in his power to make sure that the laptop is fixed. Using it as the user would by placing it in a rolling bag and putting it in the car, taking out of the car, rolling it over different types of terrain, everything short of getting on an airplane can almost guarantee that it will not break again if his theory is correct.
