The partition /dev/sdb2 has been set aside for paging. Type the command that prepares it as a swap area (it does not activate it).
LPIC-1 Exam 101-500, objective 104. Devices, Linux filesystems, filesystem hierarchy standard easy
Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.

Answer
Type the answer.
Accepted answer
mkswap /dev/sdb2
Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
mkswap writes the swap signature, a UUID and the usable size onto the partition or file; it is the swap equivalent of mkfs. The area is then activated with `swapon /dev/sdb2` for the current boot, and made permanent with an /etc/fstab line whose type is `swap`. `swapon --show` or `free -h` confirms it is in use.

- Prepare swap space with mkswap.
Practise this
Reading one question is not practice. The trainer will draw a short set from objective 104 and space the ones you get wrong.

- `df -h /var` reports the filesystem 100% full, but `du -sh /var` accounts for only about half that space. Nothing is hidden under a mount point. What is the most likely explanation? machine-checked
