Which commands will archive /home and its content to /mnt/backup? (Choose TWO correct answers.)

`cp -a` copies recursively while preserving file attributes (permissions, timestamps, symlinks), and `-r` ensures recursive copying, creating a full copy of /home under /mnt/backup.

`mv` moves the directory rather than archiving it, which would destroy the source at /home rather than creating a backup copy.

`sync` flushes filesystem write buffers to disk and is not used for copying or archiving directory trees.

`tar -cf` creates a new tar archive file at the specified path containing all files and directories under /home, making it a standard archiving solution.

`copy` is not a standard Linux command; the correct command for copying files is `cp`.
