Answer: D

QUESTION 47
Click the Exhibit button. In the exhibit, ISP A is charged a higher rate for traffic sent to R2. You are asked to lower costs for ISP A by configuring R1 to send traffic to R3 whenever possible. What are two ways to do this? (Choose two.)

A.    set protocols bgp group isp-b neighbor 192.0.2.6 local-preference 120
B.    set protocols bgp group isp-b neighbor 192.0.2.6 local-preference 80
C.    set protocols bgp group isp-b neighbor 192.0.2.10 local-preference 120
D.    set protocols bgp group isp-b neighbor 192.0.2.10 local-preference 80

Answer: BC

QUESTION 48

A.    The 172.20.20.0/24 route is installed in the inet.0 table with the next hop of the LSP.
B.    The 172.20.20.0/24 route is installed in the mpls.0 table with the next hop of the LSP.
C.    The 172.20.20.0/24 route is installed in the inet.3 table with the next hop of the LSP.
