I thought FCAF was the right one, but I guess not.

Wait, are we sure about that? What if the policy changes?

It's definitely FC H1, high for EF traffic.

This is a straightforward question. The policy is applied correctly, so the answer has to be A.

Haha, I bet the exam writer thought they could trick us with those tricky answer options. Nice try, but I'm not falling for it!

I agree with John. The traffic stream has the required DSCP and dot1p values, so it should be forwarded with the FC H1 and high priority.

The answer is clearly A) FC H1, high. The DSCP and dot1p values match the SAP-ingress policy.

I think I saw a question like this before, and it had something to do with FCAF being low priority, but I can't remember if that applies here.

I feel like I might be mixing up the dot1p values with the forwarding classes. Wasn't 4 supposed to indicate a high priority?

Okay, I've got a strategy. First, I'll carefully analyze the SAP-ingress policy to see how the DSCP and dot1p values are used to determine the forwarding class and priority. Then, I'll apply that knowledge to the given traffic stream details to select the correct answer.

I'm a bit confused by the policy diagram. I'll need to make sure I understand how the DSCP and dot1p values map to the forwarding classes and priority levels. Maybe I should review the relevant networking concepts before attempting this question.

I practiced a similar question where EF was involved, and I think it was always associated with FC H1, but I can't recall the exact priority level.

I agree, EF usually means high priority.

I remember something about DSCP values, and I think EF usually maps to a high priority, but I'm not entirely sure about the forwarding class.

I think it's A) FC H1, high. Makes sense for EF.

Okay, let me think this through step-by-step. The policy is applied to a Nokia 7750 SR, and the traffic stream has DSCP set to EF and dot1p set to 4. I'll need to cross-reference those values with the policy to find the matching forwarding class and priority.

Hmm, this looks like a tricky one. I'll need to carefully analyze the SAP-ingress policy and the traffic stream details to determine the correct forwarding class and priority level.

But we need to check the dot1p value too.
