Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 4

After checking the OSPF neighbor state, the administrator discovers that the router has established a TWOWAY state with the peering router.
What can be understood from this information? (Choose two)

Answer options

• A. The routers are configured using the same process ID
• B. The routers are configured using the same area ID
• C. The routers are configured using wrong router ID
• D. The routers are considered DROthers in a broadcast network

Correct answer: C, D

Explanation

The correct answers are C and D. A TWOWAY state indicates that the routers have successfully communicated but have not yet established full adjacency, often due to an incorrect router ID (C) and the routers being categorized as DROthers in a broadcast environment (D). Options A and B are incorrect because the TWOWAY state does not guarantee that the process ID or area ID match.
