CompTIA Server+ (SK0-004) — Question 46

Which of the following represents the directory permissions to provide least privilege for publicly readable directories on a Unix web server?

Answer options

• A. rwxrwxrwx (777)
• B. rwxrwx-w- (772)
• C. rwxrwxr-x (775)
• D. rwxrwx-x (771)

Correct answer: C

Explanation

The correct answer is C, rwxrwxr-x (775), as it allows the owner and group to have full permissions while giving only read and execute permissions to others, which is ideal for maintaining least privilege. Option A (777) grants full permissions to everyone, which is insecure, while Option B (772) and D (771) restrict permissions unnecessarily for the group or others, limiting functionality.
