I’m leaning towards options A and C, but I’m a bit confused about whether packets can change classes once they’re classified.

I practiced a question similar to this, and I feel like marking at the first egress point is a common misconception.

I think option C sounds familiar because it relates to how packets are treated based on local policies, but I can't recall the specifics.

I remember that packet classification is crucial for QoS, but I'm not sure if it has to be consistent at all ingress points.

I'm pretty confident that the write caching in HPE GreenLake involves NVDIMM. That's a common caching technique for enterprise storage solutions, so I'll go with option A.

I'm not entirely sure about this one. I'll make my best guess, but I might need to come back to it if I have time at the end.
