Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 236

An engineer is implementing NSR with OSPF on a large campus that requires high availability. Which task must an engineer perform to complete the process with minimal disruption to traffic?

Answer options

• A. Increase the keepalive interval on the OSPF neighbors so that traffic continues to pass during the switchover.
• B. Ensure that the dual RP has synchronized their state information before performing the switchover operation.
• C. Reset OSPF neighbor sessions to maintain state information during router switchover.
• D. Configure the device to repopulate state information using routing updates received from the BDR.

Correct answer: B

Explanation

The correct answer is B because ensuring that the dual RP has synchronized their state information is crucial for a seamless switchover, preventing traffic disruption. Options A and C do not address the need for synchronized state information, which is vital for continuity. Option D is not the correct approach since it focuses on repopulating state information after a disruption rather than preventing it.
