A seems too slow with the SPF calculation.

I keep mixing up the terms, but I think A could take longer since it involves recalculating. I’m not confident, though!

I practiced a similar question where FRR was emphasized, so I’m leaning towards C as well. It seems like the most efficient recovery method.

I'm not entirely sure, but I feel like switching to a secondary path could be faster than recalculating the FIB. Maybe B is the right choice?

I remember something about how fast reroute (FRR) can help with link failures, so I think C might be the quickest option.

This seems straightforward. I'll focus on the requirement of keeping deleted objects for 90 days and look for the parameters that enable that.

Okay, let me see. An RFP is used to communicate requirements to potential vendors, so option A seems like the best fit. I'll go with that unless I can come up with a better answer.
