XK0-006 Practice Question: A Linux administrator needs to ensure that only…
A Linux administrator needs to ensure that only the root user can run commands in the /usr/local/bin/scripts directory. Which command should be used to set the appropriate permissions?
⚠ Common exam trap
Watch out — candidates often choose 755 or 750 as 'standard' permissions for directories, forgetting that the requirement explicitly restricts access to only root, not to any group or other users.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
chmod 700 /usr/local/bin/scripts
The requirement is that only the root user can run commands in the directory. Permission 700 (owner: rwx, group: ---, others: ---) grants full access exclusively to the owner (root), while denying all access to the group and others. This matches the requirement precisely.
