Which type of EIGRP router entry describes a feasible successor?

A.
a primary router, stored in the topology table

B.
a backup router, stored in the routing table

C.
a backup router, stored in the topology table

D.
a primary router, stored in the routing table

Explanation:
EIGRP uses the Neighbor Table to list adjacent routers. The Topology Table list all the learned routers to destination whilst the Routing Table contains the best route to a destination, which is known as the Successor. The Feasible Successor is a backup route to a destination which is kept in the Topology Table.
