When windows VM is suspended, is that Sleep or Hibernate?

Or something else entirely?

 

Like in OSX when you click the red close button on the windowed windows VM, what does that trigger in windows?

 

Would I be correct if I presumed "Sleep" is the answer to this query?

 

Or would "Hibernate" be the correct presumption?

 

Or none of the above?

 

It must be one of those options, right?

 

Since the team doesn't know, then how would one figure it out?
