The EXP bits of the MPLS header sound familiar, but I’m not entirely confident about how they fit into GRE tunnels.

I feel like the IP precedence bits might be relevant too, but I can't recall if they are still commonly used.

I remember practicing a question similar to this, and I think the dot1p bits are definitely one of the answers.

I think we can use the DSCP bits in the ToS field, but I'm not sure about the second option.

I'm a bit confused by this question. It's talking about the future use of optical fiber networks, but I'm not sure if that means they'll completely replace other technologies for power consumption links. I might have to make an educated guess on this one.

I think I've seen something about PC forms being supported, but I'm not sure about the other options. I'll need to read the question carefully and think through the different form types.
