I think it could change at PE2, but not sure.

I feel like the answer could be 3, but I need to double-check how the QoS policies affect the marking between PE1 and PE2.

I'm a bit confused about the default trust states. Does that mean the dot1p value remains unchanged through the routers?

I think we practiced a similar question where we had to determine the dot1p value based on DSCP markings. If I recall correctly, af11 usually maps to a dot1p value of 2.

I remember that af11 corresponds to a certain level of priority, but I'm not entirely sure how that translates to the dot1p value at PE2.

Hmm, this one seems a bit tricky. I think the Designer windows and Object Explorer are the two correct answers, but I'll double-check the documentation just to be sure.

Hmm, I'm a bit unsure about how to approach this. I know I need to take the derivative twice, but I'm not sure if I should do the derivatives separately or together. I'll have to think this through carefully.

Hmm, I'm a bit unsure about this one. I know project management involves a lot of different tools and techniques, but I'm not sure which one specifically deals with resource allocation. I'll have to read the options carefully.

I hope the correct answer isn't D) 6, because that would be a real Dot1p in the head for the test-takers.

Okay, let's think this through. The question says the QoS policies are applied at the routers, so that should give us a clue.

Hmm, this is a tricky one. I'm not sure if the DSCP marking or the Dot1p value takes precedence in this scenario.
