JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 58

After receiving a BGP route, which two conditions are verified by the receiving router to ensure that the received route is valid? (Choose two.)

Answer options

• A. The AS-path length is greater than 0.
• B. The loops do not exist.
• C. The next hop is reachable.
• D. The local preference is greater than 0.

Correct answer: B, C

Explanation

The correct answers are B and C because the receiving router needs to ensure that there are no routing loops and that the next hop is reachable to confirm the validity of the route. Options A and D, while relevant to BGP, do not directly pertain to the immediate validation process for received routes.
