CCDE: Cisco Certified Design Expert (Written) — Question 16

Your company requires two diverse multihop External Border Gateway Protocol peerings to a partner network. Which two methods would you use to improve lost peer detection? (Choose two.)

Answer options

• A. Use Bidirectional Forwarding Detection for the peers.
• B. Use Selective Address Tracking and match the peers.
• C. Use subsecond keepalives for the peers.
• D. Use subsecond hold timers for the peers.
• E. Use Fast Peering Session Deactivation for the peers.
• F. Use subsecond minimum route advertisement Interval timers for the peers.

Correct answer: B, E

Explanation

The correct answers, B and E, focus on improving peer detection efficiency. Selective Address Tracking (B) allows for better management and identification of peer connections, while Fast Peering Session Deactivation (E) enables quicker recovery from lost connections. The other options, while relevant to BGP performance, do not specifically enhance lost peer detection as effectively.
