Answer options

• A. stateful firewall
• B. deep packet inspection
• C. in-service software upgrades
• D. graceful Routing Engine switchover
• E. nonstop active routing

Correct answer: C, D, E

Explanation

The separation of the control and forwarding planes allows for in-service software upgrades (C), enabling updates without downtime. It also facilitates graceful Routing Engine switchover (D), allowing for seamless transitions during failovers. Additionally, nonstop active routing (E) ensures that routing information remains available even during maintenance. The other options, stateful firewall (A) and deep packet inspection (B), are not directly related to the separation of these planes.
