I agree with Lawrence. A is the best choice here.

I lean towards A. It fits the 20% limit perfectly.

D sounds wrong. 1Gbps isn't unreserved if 1Gbps is being used.

C makes sense too. 100Mbps for the LSP is reasonable.

I feel like B could be misleading. Only 20% is allowed.

Wait, can LSPs really reserve that much? Sounds off.

D is the right answer, but I'm still trying to figure out who came up with this question. Must be a network engineer with a twisted sense of humor.

D is the way to go. Though I'm tempted to choose B just to see what happens. Yolo!

D makes the most sense to me. Reserving 1Gbps on a 10Gbps link with 20% limit? Easy peasy.

I feel like the head end reserving 100Mbps for the LSP could be a trick answer, but I can't recall the specifics on that.

I’m confused about the 20 percent limit; does that mean we can only use a fraction of the total bandwidth?

I remember a similar question where we had to calculate reserved bandwidth, and I think the answer might be A.

Based on the information provided, I think the answer is D. The egress RSVP interface has 1Gbps of bandwidth unreserved since the LSP reserved 1Gbps out of the 2Gbps max.

I think the egress RSVP interface has 80 percent bandwidth unreserved, but I'm not entirely sure how that calculation works with the limits.

I'm a bit confused on the RSVP interface limits. Is the 20% reservable bandwidth a hard cap or can it go over that? I'm not sure if B or D is correct.

I'm pretty confident the answer is D. The RSVP interface has a 20% reservable limit, so 2Gbps out of the 10Gbps link. The LSP reserved 1Gbps, leaving 1Gbps unreserved on the egress interface.

Okay, let me see... the link is 10Gbps and the RSVP interface is limited to 20% reservable, so that's 2Gbps max. The LSP is reserving 1Gbps, so I think the answer is D.
