Huawei Certified ICT Professional – Data Center Network (HCIP-DCN) — Question 28

The Hold time in the Open message sent by BGP Peer A is 90s, while that in the Open message sent by Peer B is 30s. What is the interval for sending Keepalive messages after the two peers establish a connection?

Answer options

• A. No Keepalive messages will be sent
• B. 90s
• C. 10s
• D. 30s

Correct answer: C

Explanation

The Keepalive interval is determined by the smaller Hold time value, which in this case is 30 seconds from Peer B. However, Keepalive messages are sent every 1/3 of the Hold time, resulting in a 10-second interval. Therefore, option C is correct, while the others do not reflect the correct timing.
