CCNA: Cisco Certified Network Associate — Question 34

An engineer configured an OSPF neighbor as a designated router. Which state verifies the designated router is in the proper mode?

Answer options

• A. Init
• B. 2-way
• C. Exchange
• D. Full

Correct answer: D

Explanation

The Full state indicates that a designated router (DR) is fully adjacent with its neighbors and has exchanged all necessary routing information. The Init, 2-way, and Exchange states do not confirm the complete adjacency and information exchange required for a router to be recognized as a designated router.
