Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    The backup script lacks write permission to the destination directory or file.

    Why this is correct

    The log explicitly states 'Permission denied writing to /mnt/backup/backup.tar.gz'.

  • ✗

    The mount point /mnt/backup is not accessible.

    Why it's wrong here

    The error is about permission denied, not mount failure.

  • ✗

    The cron job is running too frequently, causing a race condition.

    Why it's wrong here

    The error is consistent each run, not intermittent.

  • ✗

    The backup script is not executable.

    Why it's wrong here

    The script runs, as shown by the cron log executing it.
