Q-in-Q is a Layer 2 technique, no doubt!

I thought ToS was more for Layer 3?

Dot1p is definitely a Layer 2 field.

ToS seems like it could be relevant, but I remember it being more associated with IP packets rather than Layer 2 frames.

I'm not entirely sure, but I feel like DSCP is more for Layer 3, not Layer 2.

I think I remember that Dot1p is related to VLAN tagging, so it might be the right answer here.

I practiced a similar question about Layer 2 fields, and I think PREC could be marked, but I'm not confident.

Hmm, the Customer for Life plan sounds like it could be problematic in terms of GDPR. I'm thinking it might conflict with the requirement for consent to be as easy to withdraw as it is to give. I'll need to double-check that, but that's my initial impression.

Hmm, I'm a bit unsure about this one. MPLS can get a little tricky, but let me try to break it down step-by-step.
