   A file 'data.txt' has two hard links: 'data.txt' and 'link.txt'. What happens when the user runs 'rm link.txt'?

   • AThe command fails because a file with multiple links cannot be removed.
   • BThe link count stays at 2 because rm only removes symbolic links.
   • CThe link count decreases from 2 to 1, and the data remains accessible via data.txt.
   • DThe file's data is deleted immediately, and data.txt becomes a broken link.

   You have a symbolic link /tmp/link that points to /var/log/app.log. The target file is deleted. What happens when you access /tmp/link?

   • AThe access automatically recreates the target file from the link.
   • BThe access returns an empty file because the link is now a hard link to the deleted file.
   • CThe access still works because the symbolic link contains a copy of the file content.
   • DThe access fails with a 'No such file or directory' error because the target no longer exists.
