Huawei Certified Network Professional – Routing and Switching (HCNP-RS, legacy) — Question 15

Over a working TCP connection, what is the state of the BGP peer relationship if the peer AS number configured for a BGP router is inconsistent with the AS number of its BGP peer?

Answer options

• A. Idle
• B. Active
• C. OpenSent
• D. Established

Correct answer: B

Explanation

The correct answer is B, Active, because when there is an AS number mismatch, the BGP peer relationship cannot be established, but it is still in the process of attempting to connect. The other states, Idle, OpenSent, and Established, indicate scenarios where the connection is either not initiated, is waiting for an acknowledgment, or has been successfully established, none of which apply to an AS number inconsistency.
