Designing Cisco Enterprise Networks (ENSLD) — Question 1

Which feature is required for graceful restart to recover from a processor failure?

Answer options

• A. Cisco Express Forwarding
• B. Virtual Switch System
• C. Stateful Switchover
• D. Bidirectional Forwarding Detection

Correct answer: C

Explanation

The correct answer, Stateful Switchover, enables the system to maintain its state during a failover, ensuring a seamless transition. Cisco Express Forwarding, Virtual Switch System, and Bidirectional Forwarding Detection do not provide the same level of state preservation during a processor failure.
