JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing (2022) — Question 48

You must establish an MPLS LSP between two locations. You are required to ensure that the LSP traverses specific routers within the network.
Which solution is correct in this scenario?

Answer options

• A. Enable traffic engineering within RSVP and enable the Fast Reroute feature
• B. Implement RSVP and define the explicit route the LSP must follow
• C. Implement LDP and define the explicit route the LSP must follow
• D. Enable traffic engineering within LDP and define the explicit route the LSP must follow

Correct answer: B

Explanation

The correct answer is B because using RSVP allows you to define an explicit route for the LSP, ensuring it passes through the desired routers. The other options either don’t provide explicit route definition or use protocols that are not suitable for this requirement.
