Question 26

Refer to the exhibit. An engineer is designing a BGP solution for a client that peers with ISP1 for full Internet connectivity and with ISP2 for direct exchange of routes for several third parties. Which action, when implemented on the edge routers, enables the client network to reach the Internet through ISP1?

A.Advertise a default route for downstream routers within the client network.

B.Run an eBGP session within different VRFs for each ISP.

C.Apply route filtering such that the client advertises only routes originated from its own AS.

D.Apply the AS-path prepend feature for ISP2.

Question 27

What is the function of the multicast Reverse Path Forwarding check?

A.It allows for a loop-free distribution tree from the source to receivers.

B.It serves as an Auto RP Mapping agent.

C.It prevents bootstrap messages from reaching all routers.

D.It is used to discover and announce RP-set information.

Question 28

Which design consideration must be made when dual WAN Edge routers are deployed at a branch site?

A.Use BGP AS-path prepending to influence egress traffic and use MED to influence ingress traffic from the branch.

B.HSRP priorities must match the OMP routing policy to prefer one WAN Edge over the other.

C.Traffic must be symmetrical as it egresses the WAN Edges and returns from remote sites for DPI to function properly.

D.Configure BFD between WAN Edge routers to detect sub-second link failures.

Question 29

A router running ISIS is showing high CPU and bandwidth utilization. An engineer discovers that the router is configured as L1/L2 and has L1 and L2 neighbors. Which step optimizes the design to address the issue?

A.Configure each interface as either L1 or L2 circuit type

B.Configure the router to be either L1 or L2

C.Disable the default behavior of advertising the default route on the L1/L2 router

D.Make this router a DIS for each of the interfaces
