I thought the SAP-ingress policy had to be applied first, so maybe E?

D is interesting too, but I doubt queue 3 is completely empty.

Luis 12 months ago

Wait, could it be C? Misconfigured IP-match sounds plausible.

Totally agree, A makes the most sense here.

Lawrence 1 year ago

I think it's A. Default forwarding class usually sends ICMP to queue 1.

I feel like queue configurations matter a lot, but I can't recall if having no rate set for queue 3 would prevent it from holding packets.

I practiced a similar question where the SAP wasn't applied correctly, and that caused issues. Could that be what's happening here?

I'm not entirely sure, but I think if the IP-match criteria is wrong, it could definitely cause the traffic to end up in the wrong queue.

I remember something about default forwarding classes; could it be that ICMP is just being treated as best effort and going to queue 1?

Hmm, this is a tricky one. I think backlog refinement and program increment planning are the two team-level events, but I'm not totally confident.

I've got a good feeling about option B. Inserting the watermark image through the Headers & Footers seems like the most logical solution to me.

I'm pretty confident that option B is the right answer here. Redundant controllers in the least restrictive regulatory domain seems like the best way to ensure the highest number of channels.
