For any of the LFA methods to work properly, there must be a router in the backup path that will forward traffic addressed to the destination without sending it back to the source. Which of the following statements describes the way R-LFA selects such a router?

AIt selects an immediate neighbor.

BIt selects a remote router, reachable through a tunnel defined by a single Node-SID.

CIt selects a remote router, reachable through a tunnel defined by a Node-SID and one or two Adjacency-SIDs.

DIt can select an immediate neighbor or a remote router, as long as the backup path coincides with the path that will become active after IGP reconvergence.

Suggested Answer: D

R-LFA (Remote Loop-Free Alternate) is a method that can select either an immediate neighbor or a remote router to be used as a backup next hop, as long as the backup path coincides with the path that will become active after IGP reconvergence.

R-LFA picks a remote router with Node-SID and Adjacency-SIDs.

I vaguely remember that it can choose either an immediate neighbor or a remote router, depending on the backup path. That sounds right, doesn't it?

I feel like the answer could be about selecting a remote router with Adjacency-SIDs too, but I can't recall the specifics.

I remember practicing a question similar to this, and I think it had something to do with selecting a remote router through a Node-SID.

I think R-LFA might select an immediate neighbor, but I'm not entirely sure if that's always the case.

Okay, let me see here. I remember something about Oracle not supporting customized virtual machines, so I'm thinking B or D might be the right answer.

Hmm, I'm a bit unsure about this one. I know MPLS is related to routing, but I'm not super familiar with the specific utilities used to troubleshoot it. I'll have to think this through carefully.

This seems straightforward. I'm pretty confident that options A and D are the correct actions to take to ensure the Microsoft Teams media traffic is processed by the QoS solution.
