CompTIA Linux+ XK0-006 (V8) Practice Question

During an investigation into why a backup script cannot overwrite its snapshot file even when running as root, you gather the following information:

$ ls -l /mnt/backup/snapshot.img
-rw-r--r-- 1 root root 104857600 Aug  5 12:48 /mnt/backup/snapshot.img

$ lsattr /mnt/backup/snapshot.img
----i---------e---- /mnt/backup/snapshot.img

You need to allow the script to overwrite (replace) the file without changing any other extended attributes. Which command accomplishes this goal?

  • chattr -i /mnt/backup/snapshot.img

  • chattr +i /mnt/backup/snapshot.img

  • chmod +w /mnt/backup/snapshot.img

  • setfacl -m u:root:rw /mnt/backup/snapshot.img
