I feel like A) is more about confirming receipt, not order.

A) Acknowledge number is important too, but not for order.

I think it's D) Sequence number. It keeps track of the order.

I thought checksum was for error checking, not ordering?

Wait, isn't TTL just for time limits?

I'm going with D. Sequence number is the way to go. It's like putting Humpty Dumpty back together again.

The checksum is more about error checking, right? So I don't think that's the right choice for maintaining order.

I think the sequence number is what we need to keep track of the order of packets, but I'm not entirely sure.

The sequence number is the key piece of information needed here. That's what allows the FTP server to put the packets back in the right order when reconstructing the file. I'm pretty sure about that.

Okay, let me think this through. The sequence number has to be the right answer - that's how the FTP server keeps track of the order to reassemble the file correctly. I'm feeling pretty confident about that.

Sequence number is definitely the way to go here. That's how the server knows the order to put the packets back together. The other options don't seem relevant for maintaining the order.

I remember practicing a similar question where we discussed how packets are reassembled, and I think the sequence number was definitely mentioned.

I'm a bit confused about the acknowledge number and sequence number; they both seem related to packet order, but I can't recall the exact difference.

Hmm, I'm a bit unsure about this one. The sequence number seems like the obvious choice, but I want to double-check the other options just to be sure I'm not missing something.
