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.

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).
