JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing (2022) — Question 24

You are deploying an RSVP-based MPLS network in your core. You must ensure that your LSPs are continually analyzing the usage levels and recalculating the best LSP. You also want to ensure that a minimal amount of traffic is lost when an LSP is re-signaled without user intervention.
Which two features must be enabled in this scenario? (Choose two.)

Answer options

• A. adaptive
• B. MPLS fast reroute
• C. class of service
• D. auto-bandwidth

Correct answer: B, D

Explanation

MPLS fast reroute (B) helps in minimizing traffic loss during LSP re-signaling by providing a backup path, while auto-bandwidth (D) allows for dynamic adjustment of bandwidth based on usage levels. The other options, adaptive (A) and class of service (C), do not specifically address the requirements for continuous monitoring and minimal traffic disruption during LSP changes.
