• B. The Public IPs of the routers should be able to ping each other.
• C. To enable 2547oDMPVN - Traffic Segmentation Within DMVPN configure multiprotocol label switching (MPLS) by using the mpls ip command

Refer to the exhibit. The Customer Edge router (AS 65500) wants to use AS 100 as the preferred ISP for all external routes.


Customer Edge route-map SETLP
set local-preference 111
!
router bgp 65500
neighbor 192.168.111.1 remote-as 100
neighbor 192.168.111.1 route-map SETLP out
neighbor 192.168.112.2 remote-as 200

This configuration failed to send routes to AS 100 as the preferred path. Which set of configurations resolves the issue?

• A. route-map SETLPset local-preference 111!router bgp 65500neighbor 192.168.111.1 remote-as 100neighbor 192.168.111.1 route-map SETLP in

Refer to the exhibit. An engineer must configure router R101 for SSH access on ports 2001 through 2011. After the configuration, some expected ports were inaccessible. Which command resolves the issue?

• A. ip ssh port 2001 rotary 11line vty 0 4transport input telnet
• B. ip ssh port 2000 rotary 11line vty 0 4transport input ssh
• C. ip ssh port 2000 rotary 1 11line vty 0 4transport input all
• D. ip ssh port 2001 rotary 1 11line vty 0 4transport input ssh

Refer to the exhibit. A PC is configured to obtain an IP address automatically, but it receives an IP address only from the 169.254.0.0 subnet. The DHCP server logs contained no DHCPDISCOVER message from the MAC address of the PC. Which action resolves the issue?

• A. Configure a DHCP reservation on the server for the PC.
• B. Configure an ip helper-address on the router to forward DHCP messages to the server.
• C. Configure DHCP Snooping on the switch to forward DHCP messages to the server.
• D. Configure a static IP address on the PC and exclude it from the DHCP pool.

How does BFD protocol work?

• A. When BFD declares a failure on the primary IGP path, the router on the peer router chooses to use the secondary path.
• B. BFD operates on the route processor module and impacts the route processor CPU utilization.
• C. BFD control packets are sent via UDP port 3784 to the destination router.
• D. BFD echo packets are sent to the same source IP and different destination IP with TCP port of 3786.

What is a MPLS PHP label operation?

• A. Downstream node signals to remove the label.
• B. It uses implicit-NULL for traffic congestion from source to destination forwarding.
• C. PE removes the outer label before sending to the P router.
• D. It improves P router performance by not performing multiple label lookup.

Refer to the exhibit. An engineer is trying to configure local authentication on the console line, but the device is trying to authenticate using TACACS+.
Which action produces the desired configuration?

• A. Add the aaa authentication login default none command to the global configuration.
• B. Replace the capital C with a lowercase c in the aaa authentication login Console local command.
• C. Add the aaa authentication login default group tacacs+ local-case command to the global configuration.
• D. Add the login authentication Console command to the line configuration

Refer to the exhibit. The administrator noticed that the connection was flapping between the two ISPs instead of switching to ISP2 when the ISP1 failed. Which action resolves the issue?

• A. Include a valid source-interface keyword in the icmp-echo statement.
• B. Reference the track object 1 on the default route through ISP2 instead of ISP1.
• C. Modify the static routes to refer both to the next hop and the outgoing interface.
• D. Modify the threshold to match the administrative distance of the ISP2 route.
