Linux Essentials (010-160) — Question 69

Which one of the following statements concerning Linux passwords is true?

Answer options

• A. All passwords can be decrypted using the system administrator's master password.
• B. Passwords may never start with a non-letter.
• C. Users cannot change their password once it has been set.
• D. Passwords are only stored in hashed form.
• E. Passwords may be at most six characters long.

Correct answer: D

Explanation

The correct answer is D because Linux stores passwords in a hashed format to enhance security, making them difficult to retrieve in plain text. Option A is incorrect as there is no master password that can decrypt all passwords. Options B, C, and E are also incorrect as they impose unnecessary restrictions that are not true for Linux password policies.
