I remember that `swapon --s` command, but I'm a bit confused about how to ensure it mounts automatically on boot.

I feel like I might have mixed up the commands for adding it to `/etc/fstab`. Should it be `swap` or `swapfile`?

I practiced a similar question where I had to set up a swap partition, and I think I used `mkswap` to format it.

This seems simple enough, but I want to double-check that I'm not supposed to remove or modify the existing swap partitions. I'll be really careful to just add the new one as instructed.

Okay, I think I've got this. The key is to not touch the existing swap partitions, just add a new one. I'll follow the steps in the explanation - fdisk, mkswap, swapon, and update fstab. Should be good to go!

Hmm, I'm a bit unsure about this one. Do we need to modify the existing swap partitions at all, or just add a new one? I want to make sure I don't accidentally mess anything up.

This looks straightforward. I'll start by using fdisk to create a new 500M partition, then set it up as a swap partition and add it to fstab so it mounts automatically.

Okay, let me think this through. I know the control file can't be backed up manually as a binary copy, but I believe it can be backed up manually as a trace file. And I'm pretty sure it gets backed up automatically by RMAN when a database backup occurs.

I bet the exam creator is just testing our ability to follow instructions to the letter, even if they don't make the most sense. Next up, they'll ask us to manually edit the /etc/fstab file. Ah, the joys of system administration!

The explanation is on point, but I can't help but wonder if the exam creator is trying to trick us with a 'don't remove and modify' clause. I'll double-check everything before submitting my answer.
