CBWFQ with DSCP AF2 is solid for video, too!

Surprised LLQ is even an option, isn't it overkill for just multimedia?

I disagree, CBWFQ with DSCP AF3 might be better for mixed traffic.

I feel like LLQ with DSCP AF4 might be overkill for this scenario, but I can't quite remember the specifics of each DSCP marking.

I practiced a similar question where CBWFQ was mentioned, but I can't recall if AF2 or AF3 was the right choice for multimedia traffic.

I think DSCP EF is specifically for expedited forwarding, which seems like a good fit for streaming multimedia.

I remember studying QoS and how LLQ is often used for voice and video, but I'm not sure if it's the best choice here.

Okay, I think I've got a handle on this. The Orchestrator is all about automating the real-time processing of data from devices and sensors, right? So I'm going to go with option B.

I'm pretty sure this has to do with how certain antibiotics interact with certain foods or drinks. I think the quinolones are the ones that can't be taken with dairy, but I'm not sure about fruit juices and colas.
