CompTIA Security+ (SY0-501) — Question 71

Company policy requires the use if passphrases instead if passwords.
Which of the following technical controls MUST be in place in order to promote the use of passphrases?

Answer options

• A. Reuse
• B. Length
• C. History
• D. Complexity

Correct answer: B

Explanation

The correct answer is B, as enforcing a minimum length for passphrases ensures they are sufficiently long and secure. Options A, C, and D do not directly promote the use of passphrases; 'Reuse' pertains to how often credentials can be used, 'History' relates to previous passwords, and 'Complexity' focuses on the variety of characters used, but none specifically address length requirement which is crucial for passphrases.
