This question is a classic. B and E are the obvious choices. Although, I have to wonder if the exam writer is a time traveler, throwing in that ATM option just to see if we're paying attention. Maybe they're testing our ability to spot outdated technologies, like floppy disks and dial-up modems.

I agree, B and E are the way to go. That ATM option really threw me off!

Easy peasy! B and E are the way to go. I'd be more concerned about the service provider's choice of using GRE on a Nokia 7750 SR. Isn't that like using a flip phone to access the latest social media? But hey, at least they're not using carrier pigeons to transmit data.

Ah, the age-old question of how to mark traffic in a service provider's network. B and E are the clear winners here. I mean, who even uses ATM these days? It's like trying to find a payphone in this digital age.

This is straightforward. I'll choose B and E. The IP precedence bits are outdated, and dot1p is for Ethernet, not IP-based tunnels. As for ATM, I thought that technology was long gone, like the dinosaurs.

Hmm, the correct answers seem to be B and E. I can definitely mark traffic using the DSCP bits and the EXP bits of the MPLS header. Wonder if the exam writer is a Jedi, trying to trick us with the dark side of the force (ATM).
