Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 201

Which of the following settings could prevent two potential EIGRP neighbors from becoming neighbors? (Choose two answers.)

Answer options

• A. The interface used by one router to connect to the other router is passive in the EIGRP process.
• B. Duplicate EIGRP router IDs
• C. Mismatched Hold Timers.

Correct answer: I, P

Explanation

The correct answers are A and C because if an interface is set to passive, it will not send or receive EIGRP packets, preventing adjacency. Additionally, if the Hold Timers are mismatched, routers will not be able to maintain a stable connection. Option B is incorrect because while duplicate router IDs can cause issues, they do not directly prevent the establishment of a neighbor relationship.
