Randomly choosing? That sounds a bit off.

I think both should take R1-R3-R5-R6.

I feel like both LSPs might end up on the same path, but I can't remember if CSPF would allow that with the reservations in place.

I practiced a similar question where LSPs had to share bandwidth, and I think LSP-4 would take the path that has more bandwidth left after LSP-3 is signaled.

I remember that CSPF considers the available bandwidth when signaling LSPs, but I'm not sure how it prioritizes them in this scenario.

I think LSP-3 should take the path with less bandwidth reserved, but I can't recall if it goes for R1-R3-R5-R6 or R1-R2-R4-R6.

Hmm, this is a tricky one. I'm leaning towards the Exception Report as the best option, since it would allow the team to highlight the unexpected issues with the competitors and the potential impact on the company's position. But I'll need to double-check the details to be sure.

This looks like a tricky one. I'll need to think through the power parameter changes carefully to figure out the right answer.
