Okay, I think I've got it. The code in Segment 2 will execute one time, while the code in Segment 1 will not execute at all. I'll double-check my reasoning, but I feel good about this.

I'm feeling pretty confident about this one. The instructions are clear, and I think option C is the correct answer. Replacing the phone element with a cellPhone element using xs:redefine seems like the best approach.

Hmm, this question seems a bit tricky. I'm not totally sure about the specific terms used in the Redundant Storage pattern. I'll have to think it through carefully.

I'm pretty confident that the main function of TAILS is to allow the user to run a self-contained computer from a USB device. That way, they can use the system without leaving any traces on the host computer. I'll go with option A.
