Definitely B) TCP. UDP wouldn't work for Telnet.

Agreed! TCP is connection-oriented. Makes sense for Telnet.

I think it's B) TCP. Telnet needs a reliable connection.

Telnet without TCP? That's like trying to play chess with a rubber chicken. Clearly, B is the way to go, folks.

B) TCP, no doubt about it. Anything else and you might as well be using a tin can and a string for your Telnet connection.

B) TCP, easy peasy. Telnet without TCP would be like a car without wheels - just doesn't work.

Definitely B. TCP is the way to go for Telnet. Wouldn't want any UDP packets getting lost in the mail, am I right?

I practiced a similar question last week, and I think it was definitely TCP. It makes sense for a session-based protocol like Telnet.

I’m torn between TCP and UDP. I know Telnet needs a connection, but I can't recall if it was explicitly mentioned.

I feel like we covered this in class. Isn’t Telnet supposed to use TCP for its connections?

I'm confident that Telnet uses TCP as the underlying transport protocol. B is the answer.

Wait, isn't TCP/IP the whole suite of protocols? I'm not sure if that's the right answer here. Let me think this through again.

Okay, I remember learning that Telnet is a connection-oriented protocol, so it must use TCP. I'll select B.

Hmm, I'm a little unsure about this one. I know Telnet is a layer 7 application protocol, but I can't remember which layer 4 protocol it uses. I'll have to think this through.
