I thought LFA was more complex, surprised it’s just one SID.

Wait, are we sure about that? Seems like it could be three.

I think it’s actually two SIDs for LFA.

The backup path usually adds one SID.

I’m leaning towards 1 SID, but I’m not completely confident. This question feels tricky, and I wish I had more practice with these scenarios.

I recall that with fast re-route, the number of SIDs can vary. Could it be 4? That seems like a possibility based on what I studied.

I'm not entirely sure, but I feel like it could be 3 SIDs. I practiced a similar question last week that had a similar setup.

I think the backup path uses standard LFA, so maybe it has 2 SIDs? I remember something about that in the study material.

Hmm, I'm a bit unsure about this one. I'll need to think through the different factors the courts consider, like the employer's policies and past practices. Gotta make sure I don't miss any important details.

I'm a little confused by the options here. I know there are some URL-related functions in the language, but I'm not familiar with all of their names. I'll have to review my notes and try to reason this out.

I'm a bit confused on this one. The LFIB is used for label switching, but I'm not sure which specific field wouldn't be in there. I'll have to review my MPLS notes.

I'm a bit confused about the Basel Committee's capital adequacy requirements. Does that really tie into AML policies directly?
