Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 6

Which of the following statements regarding the router ID in OSPF are incorrect?

Answer options

• A. The router IDs of OSPF routers in the same area must be the same, but can be different in different areas.
• B. The router ID must be the IP address of an OSPF router interface.
• C. The router ID must be configured manually.
• D. A router running OSPF must have a router ID for it to operate properly.

Correct answer: A

Explanation

The correct answer is A because OSPF allows different router IDs in the same area, as they must be unique but not identical. The other options are accurate; the router ID does need to be an IP address, can be set manually, and is essential for OSPF operation.
