Open message for sure, no doubt about it!

Nope, it's not Keepalive, that's later in the process.

Wait, is it really Open? I thought it was Keepalive.

Totally agree, Open is the first one exchanged.

It's definitely the Open message!

I’m pretty certain it’s the Open message, but I might be mixing it up with the Update message from another practice question.

I feel like it could be the Keepalive message, but that seems more like a maintenance thing rather than the initial exchange.

I remember practicing a question about BGP messages, and I think it was definitely the Open message that gets sent first.

I think the first message exchanged after establishing a TCP session is the Open message, but I'm not completely sure.

This decision tree looks straightforward. I'll start by identifying the maximum expected value at each node, then work my way back to the decision point Z.

I'm a bit confused by the different options. I'll need to think through each one carefully to determine which two replacements will remove the warning.

This question seems pretty straightforward. I'm pretty confident I know the answer.

Cloud architecture seems like an option too, but I doubt it fits this setup since they specifically mention placing WLCs in the IDF.

Haha, I can just imagine the poor network admin trying to troubleshoot a BGP session that won't establish. 'Did you try turning it off and on again?'

I bet the correct answer is C) Open, because what else would you send to open up a new BGP session? Keepalive is just for keeping it alive, you know?

I agree, Open is the message exchanged to establish the TCP session between peers.
AB
Abel

Yeah, that makes sense. Open is used to establish the BGP session.
HE

I think you're right, the correct answer is C) Open.
TE
Telma

Nah, it's definitely the Open message. The question is specifically asking about the session establishment phase, so that's gotta be the right answer.
BE

Wait, is it the Update message? I thought that was used to exchange routing information, but maybe it's also used for session establishment.
BU
Burma

That's right. The Open message is the first message exchanged between BGP peers to establish the session.
MO
Moira

Oh, I see. So the Open message is used to establish the BGP session.
MA

The correct BGP message exchanged upon successful TCP session establishment is the Open message.
BR
Brice

No, the Update message is used to exchange routing information.

A) OpenSent
AY

Hmm, I was thinking it might be the Keepalive message, since that's used to maintain the connection, but I guess the Open makes more sense.
CE
Celeste

I'm pretty sure it's the Open message, since that's the one used to establish the BGP session in the first place.
ME
Melita

I'm not sure, but I think it might be B) Keepalive to maintain the session once it's established.
LI

I agree with Kaitlyn, the Open message is sent to establish the BGP session.
KA

I think the answer is C) Open because that's the first message exchanged.
