E is wrong, you can't just mkswap with a size like that!

Wait, can you really just use touch for swap? Sounds off.

I’m a bit confused about the sizes; I thought we just needed to specify the size in `mkswap`, but I can't recall the exact command.

I feel like option A is missing the `swapon` command, which seems crucial for activating the swap space.

I remember practicing a similar question, and I think option C looks right since it includes both `mkswap` and `swapon`.

I think we need to create the swap file first with `dd`, but I'm not sure if we need to use `mkswap` before `swapon`.

This one seems a bit tricky. I'll need to carefully read through the options to understand what the 'Principle of Autonomy' is referring to.

Hmm, this one seems tricky. I'll need to think carefully about the different backup methods and which one would be invalid for a SharePoint farm backup.

I'm not so confident. I thought the shared model would fit better because it implies more collaboration among agencies.
