af21 seems way off, though.

I vaguely remember that the EXP value corresponds to the DSCP marking, but I can't remember if it should be set to 3 or 4 in this scenario.

I feel like the DSCP should stay as ef since it’s already marked for expedited forwarding, but I’m not completely confident about the EXP value.

I think we practiced a similar question where the DSCP was mapped to a different value, but I can't recall if it was af21 or af23.

I remember something about DSCP values and how they relate to different classes of service, but I'm not sure if ef would remain unchanged in this case.
