Nokia 4A0-112 Exam - Topic 1 Question 1 Discussion

A series of actions are triggered on a router as a result of enabling both loopfree-alternate for a link-state routing protocol and ip-fast-reroute. Which of the following is NOT one of those actions?
A) Calculating the shortest-path next hop for each known IP prefix.
B) Calculating a backup next hop for each known IP prefix, if it exists, that would not create a routing loop if used without informing other routers.
C) Installing two entries in the FIB for IP prefixes, one active and one in standby mode.
D) Enabling the router to locally repair the active path to an IP prefix in case of failure.

I thought they all sounded right, but A is the odd one out.

Enabling local repairs seems like a key feature, but I can't recall if it directly relates to the actions listed here.

I practiced a similar question last week, and I feel like calculating the backup next hop is definitely part of the process.

I think option C sounds familiar, like it might not be something that happens with ip-fast-reroute.

I remember studying loop-free alternate, but I'm not entirely sure about the specific actions it triggers.

I think the key here is to focus on the "NOT" part of the question. That means we need to identify the action that is not triggered by enabling those features. Option C seems the most likely candidate.

I'm a bit unsure about this one. The options all seem plausible, but I'll need to review my understanding of how these features work to determine the right answer.

I'm pretty confident that the correct answer is A. Calculating the shortest-path next hop is a fundamental routing function, not something that would be triggered by those specific features.

Okay, let's see. I know that ip-fast-reroute is about providing fast local repair, so that's probably not the answer. The other options seem more related to the core functionality.

Hmm, this is a tricky one. I'll need to think carefully about the actions triggered by enabling both loopfree-alternate and ip-fast-reroute.
