The head-end router calculating based on max hop count is definitely correct.

Wait, Shared-Risk-Link Groups only for secondary paths? Really?

The head-end router calculating paths with max hop count sounds right, but I wonder if that could be the false statement here.

I feel like Shared-Risk-Link Groups are relevant for both primary and secondary paths, but I might be mixing that up with another topic.

I think I saw a practice question about TE metrics being the same as IGP metrics. That one seems familiar, but I can't recall the details.

I remember discussing hop constraints in class, but I'm not entirely sure if a strict hop has to be adjacent.

Okay, let me walk through this step-by-step. Shared-Risk-Link Groups are considered for the backup path, not the primary path, so C must be the correct answer.

The TE metric being different from the IGP metric is a common feature of SR-TE, so I'm pretty confident that option B is the false statement here.

This looks like a tricky question on SR-TE administrative constraints. I'll need to think carefully about the differences between the options.

Haha, I bet the exam writer is trying to trick us with these options. SR-TE is all about adding constraints, not removing them!

Option D sounds about right. The head-end router should be able to consider hop count and bandwidth when calculating the path.

Option A seems a bit tricky. Is a strict hop really required to be adjacent to the previous one? Doesn't SR-TE allow for more flexibility?
