JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing (2023) — Question 60

Which statement is true about the BGP active state?

Answer options

• A. The BGP active state is the initial state where all BGP traffic is refused.
• B. The BGP active state is when BGP attempts to acquire a peer by initiating a TCP connection.
• C. The BGP active state is when BGP waits for the TCP connection to be established.
• D. The BGP active state is when BGP exchanges update, notification, and keepalive messages with its peer.

Correct answer: B

Explanation

The correct answer is B because in the active state, BGP actively attempts to establish a TCP connection with its peer. Option A is incorrect as the active state does not refuse all traffic; rather, it is trying to connect. Option C describes a different state where BGP is waiting for a connection, and option D refers to the established state where messages are exchanged, not the active state.
