I thought UDP was at the transport layer, not data-link.

TFTP uses UDP, that's correct!
NI

Wait, FTP uses UDP? That's news to me!
TW

Totally agree, it's connectionless too!
SA

UDP is definitely an unreliable protocol.

I think TFTP does use UDP, so option D might be correct, but I'm a bit shaky on that one.
AL
Allene

I recall that UDP is connectionless, which makes option C true. That sounds familiar from practice questions.
DY

I'm not entirely sure, but I think FTP uses TCP, not UDP, so option B should be false.
KR

I remember studying that UDP is indeed an unreliable protocol, so I think option A is correct.
LA

Okay, let me review the key characteristics of UDP. I know it's unreliable and connectionless, so A and C are true. The other options seem plausible, but I'll double-check before answering.
TI

Wait, didn't we learn that UDP operates at the transport layer, not the data-link layer? I'm not sure about E.
GI

TFTP and FTP both use UDP ports, so D and B are also correct. I'm feeling good about this question.
AN

Hmm, I remember learning about UDP in class, but I'm not sure about the details. I'll have to think this through carefully.
GE

I'm pretty confident about this one. UDP is an unreliable, connectionless protocol, so A and C are definitely true.

This question seems straightforward, but I want to make sure I understand the key details about the fully funded plan before selecting an answer.

I might be mixing it up with another principle, but it feels like revealing too much could go against what abstraction stands for.

I've got a good feeling about this one. The key is to focus on the units and make sure the shaping rate matches the 9 Mbps traffic rate. I think I've got the right approach here.

Ooh, a tricky one! I bet the answer is just A, C, and D. I mean, come on, FTP using UDP? And the OSI layer thing? That's gotta be a trick question. Time to go with my gut on this one.
LO

Yeah, UDP is definitely a connectionless protocol.
TO

I agree, FTP does not use UDP.
TH

I think A, C, and D are correct.
BA

Alright, let's see... A, C, and D are definitely true. But B and E? FTP using UDP? And UDP at the data-link layer? Sounds like someone's trying to trip us up here. Time to put on my thinking cap!
CH

Jesusita: Yeah, I think you're right. FTP actually uses TCP, not UDP. Good catch!

User 2: I agree, but I'm not sure about FTP using UDP. It doesn't sound right.

User 1: A, C, and D are correct. UDP is unreliable and connectionless. TFTP uses UDP for communication.
LE

Ha, this is easy! UDP is the 'Unreliable Datagram Protocol' for a reason. And both FTP and TFTP use it, everyone knows that. As for the OSI layer, I'm going to go with 'true' on that one - why not, it sounds plausible enough!
CR

D) TFTP uses a UDP port for communication.
FR

C) UDP is a connectionless protocol.
LA

A) UDP is an unreliable protocol.
LA

A, C, and D are all correct, no doubt about it. But E? UDP at the data-link layer? Hmm, that sounds a bit fishy to me. Maybe the exam writers are trying to trick us on that one.

I believe D is also true, TFTP does use a UDP port for communication.
SI

I agree with Jerry, UDP is definitely unreliable and connectionless.
LA
Lauran

UDP is definitely an unreliable protocol, and TFTP does use a UDP port, so those are definitely true. But I'm not sure about FTP using UDP - I thought it used TCP. And the OSI layer thing is tricky, I'll have to double-check that one.
