- 8. As a Cisco technician, you need to know EIGRP protocol very well. Which of the following is true about EIGRP successor routes? (Choose two) A. A successor route is used by EIGRP to forward traffic to a destination B. Successor routes are stored in the neighbor table following the discovery process C. Successor routes are flagged as "active" in the routing table D. A successor route may be backed up by a feasible successor route Discuss
Correct Answer: : A D Explanation: A and D are correct because successor route is the best and primary route to a remote network A successor route is used by EIGRP to forward traffic to a destination and is stored in the routing table Its backed up by a feasible successor route in case the primary route fails, that is stored in the topology table B is incorrect because neighbor table only contains a list of directly connected EIGRP routers that have an adjacency with this router, it doesn't contain successor routes C is incorrect because successor routes found in the routing table are not flagged as "active?
- 9. Users on the 192.168.10.0/24 network must access files located on the Server 1. What route could be configured on router R1 for file requests to reach the server? A.
