010-160 Security And File Permissions Practice Question
A user reports they cannot execute a script named 'deploy.sh' even though the file permissions are set to 644. What must you change to enable execution for the owner?
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 744 deploy.sh
Permission 644 (rw-r--r--) lacks the execute bit. Changing the mode to 744 (rwxr--r--) adds execution rights for the owner.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
chmod 655 deploy.sh
Why it's wrong here
655 grants read/write to owner, but execute to group and others, which is insecure.
- ✓
chmod 744 deploy.sh
Why this is correct
744 provides rwx for the user and r-- for group/others.
- ✗
chown u+x deploy.sh
Why it's wrong here
chown changes ownership, not permissions.
- ✗
chmod +w deploy.sh
Why it's wrong here
This adds write permission, not execute permission.
