Just to clarify, it's definitely the INVITE!

I definitely recall that the INVITE is crucial for establishing a session, so I would go with option A.

I feel like the answer might be INVITE too, but I keep mixing it up with the ACK message.

I remember practicing a similar question where the INVITE was mentioned as the initial request in SIP calls.

I think the originating UAC sends an INVITE message to the UAS, but I'm not entirely sure if that's the first step.

The key is to focus on the definition of job worth hierarchy. I think I can eliminate a few of these options and narrow it down.

Wait, what's MRCP again? I'm a bit lost on the details here. I'll need to do some quick refreshing before answering.

I'm a little confused by the wording of the options. They all seem to be getting at the same general idea of Mark being able to tolerate the positions. I'll need to re-read them carefully to pick the one that best captures that.
