CCDE: Cisco Certified Design Expert (Written) — Question 3

A network design includes a long signaling delay in notifying the Layer 3 control plane that an interface has failed. Which two of these actions would reduce that delay? (Choose two.)

Answer options

• A. Enable lower data link layer recovery systems to have an opportunity to restore the interface.
• B. Increase the notification of interface flaps.
• C. Reduce the time for the network to reconverge.
• D. Increase network stability.

Correct answer: A, D

Explanation

Enabling lower data link layer recovery systems allows for faster restoration of the interface, thereby reducing the delay in notification. Increasing network stability also contributes to a more reliable environment, minimizing the chances of interface failures and the associated delays. The other options either do not directly address the signaling delay or could potentially complicate the recovery process.
