Actual exam question for Cisco's 300-510 exam

Question #: 117
Topic #: 8

Refer to the exhibit.

Router 1. Router 2. and Router 3 are co-located in an onsite data center of an office, but Router 4. Router 5. and Router 6 are installed in another data center 'eral miles away. A network engineer is troubleshooting an RSVP-TE issue on the network. On most of the devices, the engineer can move all LSPs away from a selected dace and take it down for maintenance without interrupting traffic. However, when an interface on Router 3 is taken down, traffic on the network is disrupted. What must the engineer enable to resolve the issue on Router 3?

I doubt D) would work. NSR or FRR are more reliable options.

What about D) Soft-disperse? Could that help with the issue?

I feel like A) FRR is the right choice. Fast reroute is crucial.

I think it's B) NSR. It helps with traffic continuity.

Definitely surprised that Router 3 is causing issues while others are fine.

Wait, is soft-preemption even relevant in this scenario?

I think NSR would actually be the better option here.

Soft-preemption? Is that like when you gently ask the router to step aside for a bit? I'll stick with the good old NSR.

NSR, huh? I guess that's the "non-stop routing" option. Sounds like the way to go to keep the network up and running.

D) Soft-disperse? Really? That just sounds made up. I'm going with B) NSR.

Hmm, I'm not sure. Wouldn't FRR (Fast Reroute) be a better option to avoid traffic disruption?

I feel like soft-disperse is the least likely option here, but I can't remember the specifics. I should have reviewed that section more!

Soft-preemption sounds familiar, but I can't quite recall how it applies in this scenario. Wasn't there a practice question about it?

I think it might be NSR, but I'm not entirely sure. I recall it being related to maintaining state during failovers.

This is a good RSVP-TE question that tests our understanding of different features and how they can be used to maintain network availability. I think I have a solid strategy to work through this step-by-step.

I'm a bit confused by the soft-disperse option. I'll need to research that one more to understand how it might apply here. The other choices seem more straightforward.

Okay, I see the key is that the other routers can move LSPs without disrupting traffic, but Router 3 can't. I'm leaning towards the soft-preemption feature as the solution to avoid that disruption.

I remember studying about fast reroute (FRR) and how it helps in maintaining traffic during failures. Could that be the answer here?

Sounds like they need to enable FRR for fast reroute.

I think the answer is B) NSR. That should prevent traffic disruption when an interface on Router 3 is taken down.

Hmm, the issue seems to be related to Router 3 and disrupting traffic when an interface is taken down. I'm thinking FRR or NSR might be the answer, but I'll need to double-check the details.
