Isn't UDP just unreliable by default?

I feel like multicast traffic doesn’t always need reliable transport, especially for things like streaming. So maybe option D is the right answer?

I’m a bit confused about UDP and reliability. I thought UDP was unreliable, but could it be that reliability is added at a higher layer?

I think I saw a practice question about RTP adding reliability to multicast traffic. So maybe option C is correct?

I remember that TCP is generally not used for multicast because it’s connection-oriented, but I’m not sure if that means it can’t provide reliability for multicast.

Okay, let me think this through. Multicast is one-to-many, so TCP's reliable, connection-oriented nature doesn't really fit. And option D seems too extreme - multicast does need some reliability, even if it's not as robust as unicast. I'll go with C, the RTP solution.

Hmm, this is a tricky one. I know UDP is unreliable, so option B can't be right. But I'm not totally sure about the other options. I might have to guess on this one.

I'm pretty sure TCP doesn't provide reliable transport for multicast, so I can rule out option A. I think the answer is likely C, since RTP is a higher-level protocol that can add reliability to multicast.

I'm a bit confused on this one. I know multicast is different from unicast, but I'm not sure about the specifics of how reliability works. I'll have to eliminate the options that I'm more certain are wrong, then take an educated guess on the rest.

Hmm, I'm a bit unsure about this one. The USB flash drive might be cheaper, but 600 GB is a lot of data for a flash drive. The SCSI tape backup system could work, but it might be overkill for a coffee shop's needs.

Oh, the key here is scheduling the publish without manual work. I'm pretty sure Manage Publication lets you set a specific time.

I think the Record Detail component is the best choice here, since it allows for customizing the action buttons based on the record's properties.
