I’m leaning towards Dotlp being the correct choice, but I need to double-check my notes on Layer 3 services to be certain.

I feel like PREC might be the answer since it’s more related to Layer 2, but I could be mixing things up with another topic we covered.

I remember practicing a similar question where we discussed the differences between EXP and DSCP. I think EXP can be marked, but I'm confused about the others.

Wait, what's SAP-egress? I don't think I've covered that in my studies. I'll need to look that up before attempting this.
