Surprised there's so much debate! I thought it was straightforward.

I think option B is correct. It's all about the network policy.

I feel like option D could be the right answer since it mentions a default map, which seems to align with what we discussed in class about translating DSCP codes.

I vaguely recall that the dot1p header might be involved, so maybe option C is correct? But I can't quite remember the details.

I think option B sounds familiar from our practice questions, where the SAP-ingress classification plays a role in setting the EXP bits.

I remember something about the DSCP value and how it relates to the EXP bits, but I'm not sure if it's directly copied or if there's a mapping involved.

This is a tricky one, but I'm going to go with option C. The dot1p priority bits seem the most straightforward way to set the EXP field.

I think copying the DSCP bits directly to the EXP field makes the most sense, so I'm leaning towards option A.

The key is understanding how the Nokia MPLS network handles QoS. Option D sounds like the most logical approach, translating DSCP to forwarding classes.

Hmm, I'm a bit confused on the difference between DSCP and dot1p here. I'll need to review those concepts again before deciding.

I'm pretty sure the EXP bits are set based on the network policy, so I'll go with option B.

B is the way to go, folks. Gotta love that combination of SAP-ingress and network policy. It's like a secret sauce for your MPLS network. Just don't forget the croutons.

C) The 3 priority bits are copied directly from the dot1p header into the EXP field of the first MPLS header.

Option A sounds good to me. Why do extra work when you can just copy the DSCP bits? Unless, of course, you want your network to work correctly. Hmm, tough choice.

I'm going with D. It's all about translating DSCP to internal forwarding classes, right? Keeps things nice and simple.

Option B makes the most sense to me. The EXP bits should be set based on the traffic classification and network policy, not just copied from DSCP or dot1p.

I think the EXP bits are set based on a default map that translates DSCP codes into internal forwarding classes on SAP-ingress.
