Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 243

Which two statements about the EIGRP DUAL process are correct? (Choose two.)

Answer options

• A. An EIGRP route will go active if there are no successors or feasible successors in the EIGRP topology table.
• B. An EIGRP route will go passive if there are no successors in the EIGRP topology table.
• C. DUAL will trigger an EIGRP query process while placing the flapping routes in the holddown state.
• D. A feasible successor in the EIGRP topology table can become the successor only after all the query requests have been replied to.
• E. The stuck in active state is caused when the wait for the query replies have timed out.

Correct answer: E, I, G, R, P, E, I, G, R, P

Explanation

The correct answer is E, which accurately describes the condition leading to the 'stuck in active' state. A route going active (A) occurs in the absence of successors, but it does not define the stuck condition. Statement B incorrectly describes the passive state, while C misrepresents the role of DUAL in handling flapping routes, and D is inaccurate regarding the timing of when a feasible successor can transition to a successor.
