I’m pretty confident it’s DISPLAY, but I wish I had reviewed that section more thoroughly before the exam.

I remember practicing a question like this, and I think it was definitely DISPLAY that gets set when X11 forwarding is enabled.

I think the variable we're looking for is DISPLAY, but I'm not entirely sure if there's a specific format for it.

Ah, I remember learning about this in class. The environment variable that's set is DISPLAY. I'll select that option and move on to the next question.

Hmm, I think this is about the environment variable that gets set when you enable X11 forwarding in SSH. I'm pretty sure it's DISPLAY, but I'll double-check the options just to be sure.

Wait, I'm a bit confused. Is it just the variable name we need to provide, or do we need to include the value as well? I want to make sure I get this right.

I'm a little confused by the wording of this question. What's the difference between Judgmental sampling and Discovery sampling? I'll have to think about this one a bit more.

DISPLAY, the environment variable that says 'Hey, remote host, this is where you need to send your fancy graphics!'

I think it's DISPLAY because it tells the remote host where to display the graphical interface.

DISPLAY is the obvious answer. When X11 forwarding is enabled, the remote host needs to know where to send the graphical output.
