Troubleshooting and Maintaining Cisco IP Networks (TSHOOT, legacy) — Question 13

You want to troubleshoot an OSPF adjacency issue. Which two tasks must you perform? (Choose two.)

Answer options

• A. Issue the debug ip ospf nsf command to identify the cause.
• B. Issue the debug ip ospf adj command to identify the cause.
• C. Verify that the router IDs on the two routers match.
• D. Verify that the subnet masks on the two routers match.
• E. Verify that the process IDs on the two routers match. BD

Correct answer:

Explanation

The correct tasks to perform are issuing the debug ip ospf adj command to see adjacency details and verifying that the subnet masks on the two routers match, as mismatched subnet masks can prevent OSPF neighbors from forming. The other options, while useful in some contexts, do not directly address the adjacency issue as effectively as the selected answers.
