ICND2: Interconnecting Cisco Networking Devices Part 2 (legacy) — Question 60

What does a router do if it has no EIGRP feasible successor route to a destination network and the successor route to that destination network is in active status?

Answer options

• A. It routes all traffic that is addressed to the destination network to the interface indicated in the routing table.
• B. It sends a copy of its neighbor table to all adjacent routers.
• C. It sends a multicast query packet to all adjacent neighbors requesting available routing paths to the destination network.
• D. It broadcasts Hello packets to all routers in the network to re-establish neighbor adjacencies.

Correct answer: C

Explanation

The correct answer is C because when a router has no feasible successor route and the successor route is active, it must query its neighbors for alternative routes by sending a multicast query packet. Options A and B do not address the need for alternative routing information, and option D is not relevant to EIGRP's route discovery process.
