Question:1 Click on the Exhibit button. End users on VLAN1 were experiencing slow performance. After examining the traffic on the VLAN you notice there is a high percentage of broadcast traffic. To improve performance you create a second VLAN on the Ethernet Routing Switch (ERS) 5500 and move two departments to VLAN 2. Users on VLAN 2 are now calling the help desk to report that they cannot access their email. All of the users seem to be on the 169.254.x.x network instead of the network configured on the DHCP server. After research, you learn this is the range of IP addresses that Microsoft operating systems assign when the system does not receive an IP address from the DHCP server. How can users on VLANs 1 and 2 both receive IP addresses from one DHCP server?

A. Insert a second network card in the DHCP server, connect it to VLAN 2, and enable bridging. B. Configure the VLAN 2 to forward UDP packets to the DHCP server on VLAN 1. C. Configure the Bootp/DHCP relay to forward DHCP broadcasts on VLAN 2 to the DHCP server. D. Configure the Bootp/DHCP relay to forward unicast DHCP traffic on VLAN 2 to the DHCP server. Answer: C Question:2 Click on the Exhibit button. The following steps were performed to successfully configure the Ethernet Routing Switch (ERS) 5520 to send tagged packets to the telephone and untagged packets to the PC. 1) the egress port was removed from VLAN1 2) VLAN 210 was added to the egress port 3) VLAN 110 was added to the egress port 4) the egress port was configured to tag-PVID-only Which VLAN Configuration Control mode must have been configured?

A. Strict B. Flexible C. AutoPVID D. Automatic Answer: B Question:3 A client needs to configure Internet Protocol Flow Information eXport (IPFix) to export flow information on their Ethernet Routing Switch (ERS) 5530 switch as part of their security solution. Which step must be performed first? A. Each interface must be configured with the IP address of the security server which will receive the IPFix information. B. An Advanced License must be installed on each of the ERS 5530 switches that will be exporting flow information. C. Simple Network Management Protocol (SNMP) community strings must be configured for the security server which will poll the IPFix information. D. The switch must be configured to specify the version of NetFlow messages to export. Answer: B Question:4 A customer with an Ethernet Routing Switch (ERS) 4500 is configuring RADIUS to provide a high degree of security against unauthorized access to the switch. They configured five RADIUS servers on the client, an ERS 4500 switch. What will happen if an authentication request is rejected by the first of five RADIUS servers configured on the switch? A. The login is denied. B. Local authentication is made on the switch itself. C. If the first server is unavailable, the ERS 4500 tries the second and so on until it establishes a successful connection. D. If the first server rejects the authentication request, the ERS 4500 tries the second and so on until it establishes a successful connection. Answer: A Question:5 Click on the Exhibit button. Virtual Link Aggregation Control Protocol (VLACP) is configured by port, and traffic is only forwarded across the uplinks when VLACP is up and running correctly. A = InterSwitch Trunk (IST) B = Split MultiLink Trunk (SMLT) #1 ERS 8600 #2 ERS 8600 #3 ERS 4500 When configuring VLACP for the network shown in the exhibit, where should it be configured?

A. on all IST links and not SMLT links B. on all SMLT links and not IST links C. on all IST and all SMLT links D. on none of the IST or SMLT links depicted in this network Answer: C Question:6 A white paper was recently released that showed that devices connecting to a switch with a 1 Gbps interface draw 4W more power than devices that connect to the switch with a 100 Mbps interface. The Chief Financial Officer and the Chief Technology Officer of a large energy company have reached an agreement that users have to have a 100 Mbps connection to the network even though their PCs support 1 Gbps. Nevertheless, there are other users who could be granted a Gbps connection such as engineers, servers, video conferencing equipment, and so on. Their network infrastructure has an Ethernet Routing Switch (ERS) 5500 switch and an ERS 4500 switch combined in the wiring closets. Which cost-effective configuration change should be performed on the ERS switches that would limit most users to 100 Mbps and still allow auto-mdi/mdix configuration to work? A. Configure the port speed to 100 Mbps and the duplex to full for the ports that should be limited to 100 Mbps. B. Move all the 100 Mbps users to ERS 4550T or 4550T-PWR. C. Configure the Custom Auto-Negotiation Advertisements (CANA) feature on the ports that should be limited to 10/100 Mbps. D. Configure each of the PCs that should connect at 100 Mbps to connect to the switch at 100Mbps full duplex. Answer: C
