Wait, I thought it happened before TCP?

It's definitely after a TCP handshake!

C, of course! The TLS handshake is like the secret handshake of the internet.

C is the way to go. Unless you're a hacker trying to bypass the TLS, then you're in trouble!

Definitely C. The TLS handshake comes after the TCP connection is set up.

C) After a TCP handshake has been established. That's the correct answer, right?

I’m pretty certain the handshake occurs after the TCP handshake, but I could be mixing it up with something else I studied.

I feel like I might have seen something about TLS handshakes being independent of HTTPS, but that doesn't sound right to me.

Hmm, I'm not entirely sure about this one. I know the TLS handshake is related to HTTPS, but I'm not sure if it's only during DNS over HTTPS queries or if it happens more broadly. I'll have to think about this a bit more.

I'm pretty confident that the TLS handshake happens before the TCP connection is established. That way, the secure channel is set up right from the start. So I'm going to go with option A.

Okay, I've got this. The TLS handshake is what establishes the secure, encrypted connection for HTTPS, so it has to happen before the HTTPS communication can take place. That means it's not independent of HTTPS, so I'll rule out option D.

I remember practicing a question about TLS and TCP connections, and it seemed like the handshake was part of the connection setup.

Hmm, I'm a bit confused about this one. I know the TLS handshake is related to HTTPS, but I'm not sure if it's independent of the HTTPS communication or not. I'll have to think this through carefully.

I think this is asking about when the TLS handshake happens in the connection process. I'm pretty sure it's after the TCP handshake, so I'll go with option C.
