Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 759

What is stateful switchover?

Answer options

• A. cluster protocol used to facilitate switch failover
• B. mechanism to take control from a failed RP while maintaining connectivity
• C. mechanism used to prevent routing protocol loops during an RP switchover
• D. First Hop Redundancy Protocol for host gateway connectivity

Correct answer: B

Explanation

The correct answer, B, describes how stateful switchover allows another Routing Processor (RP) to take over without losing connectivity. Option A describes a cluster protocol but does not capture the essence of maintaining connectivity. Option C focuses on preventing routing loops, which is not the primary function of stateful switchover. Option D relates to first hop redundancy but is not specific to the stateful switchover concept.
