Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 156

What are two possible causes for EIGRP Stuck-In-Active routers? (Choose Two)

Answer options

• A. Some query or reply packets are lost between the routers.
• B. The neighboring router starts receiving route updates from this router.
• C. A failure causes traffic on a link between two neighboring routers to flow in only one direction (unidirectional link).

Correct answer: A, C, K

Explanation

The correct options, A and C, indicate that lost packets and unidirectional links can prevent EIGRP from completing its route queries, causing routers to remain in an active state. Option B is incorrect because receiving route updates does not contribute to the Stuck-In-Active state.
