LPIC-3 Exam 303 (Security) — Question 18

How are SELinux permissions related to standard Linux permissions? (Choose TWO correct answers.)

Answer options

• A. SELinux permissions override standard Linux permissions.
• B. Standard Linux permissions override SELinux permissions.
• C. SELinux permissions are verified before standard Linux permissions.
• D. SELinux permissions are verified after standard Linux permissions.

Correct answer: B, D

Explanation

The correct answers are B and D because standard Linux permissions are indeed checked first, and if they allow access, SELinux permissions are then verified. Option A is incorrect since SELinux permissions do not take precedence over standard permissions, and option C is wrong as SELinux checks occur after the standard checks.
