JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 86

Your network has two ISPs available. You want to ensure that all outbound traffic is routed out ISP-1. If the connection to ISP-1 fails, all outbound traffic is routed to the backup ISP, ISP-2.

In this scenario, how should you configure BGP on your network?

Answer options

• A. Set the local-preference attribute to a higher value for ISP-1 than ISP-2.
• B. Set the local-preference attribute to a higher value for ISP-2 than ISP-1.
• C. Configure the gateway for ISP-1 with a higher origin code than the gateway for ISP-2.
• D. Configure the gateway for ISP-1 with a higher peer ID than the gateway for ISP-2.

Correct answer: A

Explanation

The correct answer, A, involves setting a higher local-preference for ISP-1, ensuring it is preferred for outbound traffic. Option B is incorrect because it prioritizes ISP-2 instead. Options C and D do not affect the outbound routing preference in the same way as local-preference does.
