B is incorrect, clients don’t acknowledge multicast streams.

Wait, so multicast is unreliable over WLAN? That's surprising!

I feel like we had a practice question that mentioned client acknowledgments for multicast, but I can't recall the details clearly.

I’m a bit confused about option A; I thought multicast traffic was inherently unreliable unless specific measures were taken.

I think option C sounds familiar because we discussed how unicast to multicast conversion works in class.

I remember something about multicast being less reliable over WLAN, but I'm not sure if that's the main point here.

I'm not too familiar with the specifics of the VideoStream/Multicast Direct feature, so I'm not 100% confident in my answer. But based on the information provided, I'm leaning towards option D as the most likely correct answer.

Option B seems like the most straightforward answer to me. The question is asking about the VideoStream feature, and B says that each client acknowledges receiving the multicast stream, which makes sense for a video streaming scenario.

Hmm, I'm a bit confused by this one. I'm not entirely sure about the differences between the options. I'll need to think through the details of each one more carefully before deciding.

I'm pretty sure the answer is C. The question is asking about the VideoStream/Multicast Direct feature, and C says it converts the unicast frame to a multicast frame over the air, which seems like the correct description of that feature.

D is the answer. Multicast is less reliable over the air, but more reliable over Ethernet. Duh, everyone knows that!
