Wait, can you really pre-mark all those fields?

I thought EXP was mentioned in our notes, but I can't remember if it was specifically for SAP-ingress or another context.

I’m leaning towards Dot1p being pre-marked, but I’m a bit confused about how it relates to the other options.

I remember practicing a similar question where we had to identify which fields could be marked on ingress. I feel like DEI might be one of them, but I can't recall clearly.

I think we discussed DSCP/PREC in class as something that can be pre-marked, but I'm not entirely sure about the others.

I think the answer is D. DSCP/PREC. That's the field in Layer 3 packets that can be pre-marked on SAP-ingress, if I remember correctly. I'm fairly confident in this answer, but I'll review the material just to be sure.

I'm a bit confused by this question. I know we're dealing with Layer 3 services, but I'm not sure which field can be pre-marked on SAP-ingress. I'll have to carefully read through the options and try to eliminate the ones that don't seem right.

Okay, let's think this through step-by-step. We're looking for a field in Layer 3 packets that can be pre-marked on SAP-ingress. That narrows it down to DSCP/PREC or EXP. I'm leaning towards DSCP/PREC, but I'll double-check my notes to confirm.

Hmm, I'm not entirely sure about this one. I think it might be A. Dot1p, but I'm not 100% certain. I'll have to review the material again to be sure.

I'm going to have to go with D. The others just seem like they'd be more for Layer 2 or something. Unless this is a trick question and the answer is actually a duck.

Hmm, I'm tempted to go with C. EXP, since that's the MPLS field for QoS. But I guess that's not really a Layer 3 thing.

Yeah, I agree. DSCP/PREC is the correct choice for pre-marking QoS in Layer 3 packets.

D for sure. The other choices are more for lower layer protocols like Ethernet and MPLS.
