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

✓

Mount the filesystem with the acl option, then use setfacl to apply ACL rules, then use getfacl to verify ACL rules.

ACLs require the filesystem to be mounted with the acl option, then setfacl applies rules, and getfacl verifies them.

Answer analysis

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

✓
Mount the filesystem with the acl option, then use setfacl to apply ACL rules, then use getfacl to verify ACL rules.
Why this is correct
This is the correct order because the filesystem must first support ACLs via the mount option, then rules can be set, and finally verified.
✗
Use setfacl to apply ACL rules, then mount the filesystem with the acl option, then use getfacl to verify ACL rules.
Why it's wrong here
This is incorrect because ACLs cannot be applied until the filesystem is mounted with the acl option; applying rules before mounting will fail.
✗
Use getfacl to verify ACL rules, then use setfacl to apply ACL rules, then mount the filesystem with the acl option.
Why it's wrong here
This is incorrect because getfacl cannot verify rules that haven't been set, and the filesystem must be mounted with acl before any ACL operations.
✗
Mount the filesystem with the acl option, then use getfacl to verify ACL rules, then use setfacl to apply ACL rules.
Why it's wrong here
This is incorrect because getfacl before setfacl would show no ACLs (or inherited ones), and rules must be set before verification is meaningful.
