The correct answer is A. Graceful Restart only protects control plane, not data plane forwarding. BGP Graceful Restart preserves routing information in the control plane, preventing route withdrawal during a restart. However, if the data plane on the Edge node is unavailable, traffic still drops.

Explanation

BGP Graceful Restart preserves routing information in the control plane, preventing route withdrawal during a restart. However, if the data plane on the Edge node is unavailable, traffic still drops. This question tests your understanding that routing stability ≠ traffic forwarding continuity-a subtle but very exam-relevant distinction.
