I see both points, but I think I will go with A) TRUE because it seems logical that if remarking is enabled in the network egress policy, the packet would be remarked at the first network egress point.

Hmm, I'm not so sure about this one. Isn't there some catch or exception to this rule? I'm going to have to go with B) FALSE just to be safe.

I disagree, I believe the answer is B) FALSE because just because a packet is marked on a SAP-ingress doesn't necessarily mean it will be remarked at the first network egress point.

Wow, this is a tricky one! But I'm pretty sure the answer is A) TRUE. The question is clearly asking about remarking at the network egress point, so it has to be true, right?

I think the answer is A) TRUE because if a packet is marked on a SAP-ingress, it makes sense for it to be remarked at the first network egress point.
