TCP port 22? That's a no-go.

Yup, definitely not UDP for BGP.

Wait, is it really port 179? I thought it was something else.

Totally agree, BGP uses TCP!

It's TCP port 179 for sure.

I’m pretty confident it’s TCP port 179, but I remember some questions that confused UDP with TCP.

I feel like BGP definitely uses TCP, but I keep mixing up the port numbers. Is it 179 or 22?

I remember practicing a question about BGP and TCP, but I can't recall if it was port 179 or something else.

I think BGP uses TCP, but I'm not sure about the port number. Was it 179?

Hmm, I'm a bit stuck on this one. I know BGP is a routing protocol, but I can't quite recall the specifics of the transport protocol and port number it uses. Maybe I should review my networking notes before answering.

I've got this! BGP uses TCP on port 179 to establish and maintain peering sessions. I remember learning that in my networking class. Time to mark this one as a sure thing.

Wait, is it TCP or UDP? I'm a little unsure about the transport protocol here. And was it port 179 or 22? I need to double-check my networking knowledge.
SU

Okay, let me think this through. BGP is a routing protocol, so it's likely using TCP for reliable data transfer. And the standard port number for BGP is 179, if I remember correctly.

Hmm, this seems like a pretty straightforward networking question. I'm pretty confident I know the answer to this one.

I've seen issues like this before. My first instinct is to check the merge code that's passing the Record ID to the DataRaptor Load. Make sure the context ID is spelled correctly and that it's referencing the right field.

This is a tricky one. I can see the appeal of options A and B, but I'm a bit concerned about the complexity of setting up and managing those services, especially for a temporary ad hoc solution. I might be tempted to go with option C, DynamoDB and DAX, as that could provide a simpler, more cost-effective solution. But I'll need to weigh the trade-offs carefully.

Okay, I've got a strategy here. I think the best approach is to ingest the data into BigQuery, convert the PySpark to BigQuery SQL, and then write the transformed data to a new table. That should give me the speed and SQL syntax I need.

Doh! I'll just go with option A and hope the force is with me.

UDP port 22? Now you're just pulling my leg. Next thing you know, they'll be asking about HTTP on port 53.

TCP port 22? Isn't that the SSH port? I think someone's been mixing up their network protocols here.
XU

Yeah, TCP port 179 is used by BGP for peering sessions. UDP port 179 is incorrect.
FL

No, it's actually TCP port 179. That's the correct port for BGP.

Haha, UDP port 179? Really? As if BGP would ever use an unreliable transport protocol like UDP. This isn't a game of 'guess the wrong answer'.
TI

Exactly, BGP needs the reliability of TCP.

A) TCP port 179.
HO

TCP port 179, of course! BGP is a connection-oriented protocol, so it has to use TCP to establish and maintain a reliable session.
MI
Mireya

I'm not sure, but I think UDP port 179 is also a valid option for BGP.
AL

I agree with Brett, BGP uses TCP port 179 for peering sessions.
BR

I think the answer is A) TCP port 179.
