Refer to the topology.

Your company has connected the routers R1, R2, and R3 with serial

links. R2 and R3 are connected to the switches SW1 and SW2, respectively. SW1 and

SW2 are also connected to the routers R4 and R5.

The EIGRP routing protocol is configured.

You are required to troubleshoot and resolve the EIGRP issues between the various

routers.

Use the appropriate show commands to troubleshoot the issues.

Which path does traffic take from R1 to R5?

A. The traffic goes through R2.

B. The traffic goes through R3.

C. The traffic is equally load-balanced over R2 and R3.

D. The traffic is unequally load-balanced over R2 and R3.

Answer: A

Explanation:

Using the “show ip int brief command” on R5 we can see the IP addresses assigned to this

router. Then, using the “show ip route” command on R1 we can see that to reach 10.5.5.5

and 10.5.5.55 the preferred path is via Serial 1/3, which we see from the diagram is the link

to R2.
