Really? I thought we had more unreserved bandwidth!

I thought it would be 2 Gbps left, but I guess not!

Wait, isn’t it 7 Gbps left after the 30% limit?

So, 10 Gbps - 1 Gbps = 9 Gbps unreserved, right?

The total bandwidth is 10 Gbps, reservable is 3 Gbps.

If I remember correctly, the 30% limit means we can reserve 3 Gbps. After reserving 1 Gbps, that leaves us with 2 Gbps unreserved. I think that's option D.

I'm a bit confused about the calculations. I remember something about reservable bandwidth percentages, but I can't recall how to apply it here. Did we practice something similar?

I think the total bandwidth is 10 Gbps, and with RSVP limiting it to 30%, that means only 3 Gbps is reservable. So if 1 Gbps is reserved, there should be 2 Gbps left unreserved, right?

I thought it was 10 Gbps total, but with the 30% limit, I’m not sure how to calculate the unreserved part. I might have mixed up the numbers from a practice question.

Hmm, I'm not totally sure about this one. I'll have to think it through carefully before answering.

Barge transport seems efficient for heavy loads, but can we really use that for petrol so far inland? I feel unsure about the distances involved here.
