Haha, this question is tricky! I'm going with B and E, but I'm not entirely confident. Maybe I should have paid more attention in the QoS class.

Hmm, I'm a bit confused. I thought sgt-qos was used to mark Layer 2 traffic, but option A seems to contradict that. And I'm not sure about the DSCP bits and forwarding class manipulation.

I think the correct answers are B and E. DSCP bits can be set per application, and the internal forwarding class is set once and applied globally.

I'm not sure about D), but I think B) is definitely true. DSCP bits can be set per application, per routing instance.

I agree with Magnolia. A) and D) make sense because they mention marking Layer 2 traffic and setting network interfaces to dot1Q.
