Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 332

Which two options are requirements for EIGRP authentication? (Choose two.)

Answer options

• A. A crypto map must be configured.
• B. The Authentication key must be configured under the interface running EIGRP.
• C. The authentication key must be configured within the EIGRP routing configuration.
• D. The authentication key IDs must match between two neighbors.
• E. A separate key chain must be configured.
• F. AN IPsec profile must be configured.

Correct answer: B, D

Explanation

Options B and D are correct because the authentication key must be set on the interface where EIGRP runs, and the key IDs must match on both neighboring routers for successful authentication. Options A, C, E, and F are not required for EIGRP authentication, as they pertain to other security configurations or protocols.
