200-101 Question #125: Real Exam Question with Answer & Explanation

The correct answer is C: R 192.168.255.16 [120/1] via 192.168.255.26, 00:00:24, Serial0/0. RIP routes appear in the routing table with the code 'R', administrative distance 120, and a hop-count metric. The correct entry must reflect the precise subnet, metric, and next-hop that match the topology shown in the exhibit.

Question

Refer to the exhibit. Which route will be found in the routing table of the Main router?

Options

AC 192.168.2.0 is directly connected, Serial0/1
BR 192.168.2.0/24 [120/1] via 192.168.255.26, 00:00:24, Serial0/0
CR 192.168.255.16 [120/1] via 192.168.255.26, 00:00:24, Serial0/0
DR 192.168.255.16 [120/2] via 192.168.255.21, 00:00:22, Serial0/0

Explanation

RIP routes appear in the routing table with the code 'R', administrative distance 120, and a hop-count metric. The correct entry must reflect the precise subnet, metric, and next-hop that match the topology shown in the exhibit.

Common mistakes.

A. A route code of 'C' denotes a directly connected interface, which is assigned by the operating system automatically and cannot be a route received from a neighboring router via RIP.
B. The /24 mask on 192.168.2.0 does not match the subnet mask assigned to that segment in the exhibit, so this entry would not appear in the routing table as shown.
D. A metric of 2 in '[120/2]' would mean the destination is two hops away, but the exhibit topology places the relevant subnet only one hop from the Main router, so metric 1 is correct.
