JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing — Question 20

Which two events could cause the BGP Active state to appear? (Choose two.)

Answer options

• A. The local router does not have a route to the peer device.
• B. The local router failed to establish a TCP connection with the peer device.
• C. A firewall is stopping all UDP packets.
• D. The BGP configuration is incomplete.

Correct answer: B, D

Explanation

Answer B is correct because if the local router cannot establish a TCP connection with the peer device, it will not be able to progress to the Established state. Answer D is also correct as an incomplete BGP configuration can prevent the session from being established, leading to the Active state. Options A and C are incorrect; while a route is needed, it does not directly cause the Active state, and BGP operates over TCP, not UDP.
