Troubleshooting and Maintaining Cisco IP Networks (TSHOOT, legacy) — Question 35

The implementation group has been using the test bed to do an IPv6 'proof-of-concept1. After several changes to the network addressing and routing schemes, a trouble ticket has been opened indicating that the loopback address on R1 (2026::111:1) is not able to ping the loopback address on DSW2 (2026::102:1).
Use the supported commands to isolate the cause of this fault and answer the following question.
The fault condition is related to which technology?

Answer options

Correct answer: B

Explanation

The correct answer is B, IPv4 OSPF Routing, because issues with routing protocols in IPv4 can affect connectivity. The problem described is isolated to IPv4 addressing and routing, which is why IPv6 OSPF Routing (C) and the other options (A and D) are not relevant to the fault condition.
