Question 4
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
- B. route-map SETPPset as-path prepend 100 100!router bgp 65500neighbor 192.168.111.1 remote-as 100neighbor 192.168.111.1 route-map SETPP in
- C. route-map SETPPset as-path prepend 111 111!router bgp 65500neighbor 192.168.111.1 remote-as 100neighbor 192.168.111.1 route-map SETPP out
- D. route-map SETLPset local-preference 111!router bgp 65500neighbor 192.168.111.1 remote-as 100neighbor 192.168.111.1 route-map SETLP out

- 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
Answer:
d
Question 6
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.
Answer:
b
Question 7
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.
Answer:
c
Question 8
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.
Answer:
a
