JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 29

What are three reasons a BGP route would be hidden? (Choose three.)

Answer options

• A. The AS Path contains a 0.
• B. It is suppressed by a damping policy.
• C. The Local Preference is 0.
• D. The next hop is unreachable.
• E. It is rejected by a firewall term.

Correct answer: A, B, D

Explanation

A BGP route can be hidden if the AS Path contains a 0, indicating a loop, which makes it invalid. A damping policy can suppress a route to prevent instability, making it hidden as well. If the next hop is unreachable, the route cannot be utilized, leading to it being hidden. The other options do not directly cause the route to be hidden in the same way.
