LPIC-1 Exam 101 v5 (Linux Administrator) — Question 20

Which of the following settings for umask ensures that new files have the default permissions -rw-r-----?

Answer options

• A. 0017
• B. 0640
• C. 0038
• D. 0227
• E. 0027

Correct answer: E

Explanation

The umask value of 0027 subtracts write permissions for group and others from the default file permissions of 666, resulting in permissions of 640 (-rw-r-----). Other options either do not yield the correct permissions or do not appropriately restrict access for the group and others.
