Nope, it's all about the port numbers!

Subnet masks seem related, but I don't think they identify services. It's either IP addresses or port numbers, but I lean towards port numbers.

I remember practicing a question like this, and I think it was port numbers that help direct packets to the right service.

I feel like I studied this, and it was definitely about IP addresses or port numbers. I just can't recall which one is correct.

I think the answer might be port numbers, but I'm not entirely sure. I remember something about them being used for specific services.

Port numbers, definitely port numbers. That's how TCP/IP distinguishes between different services running on the same IP address. I'm confident that's the right answer.

Hmm, I'm a bit unsure on this one. I know TCP/IP uses IP addresses to identify the destination host, but I can't quite remember how it identifies the specific service. Let me think this through...

This one seems pretty straightforward. I'm pretty sure the answer is port numbers, since that's how TCP/IP identifies the specific service or application a packet is destined for.

I'm a little confused on this one. Is it port numbers, or could it be something else like MAC addresses? I'll have to think it through carefully and review my notes before answering.

This is a trick question - the answer has to be port numbers. Unless the question is asking about layer 2, which would be just silly.

MAC addresses? Really? That's for layer 2, not layer 4. Port numbers are definitely the way to go here.

Subnet masks help determine which devices are on the same network, but they don't identify services like port numbers do.
