CompTIA Server+ (SK0-005) — Question 96

A company needs to increase the security controls on its servers. An administrator is implementing MFA on all servers using cost-effective techniques.

Which of the following should the administrator use to satisfy the MFA requirement?

Answer options

• A. Biometrics
• B. Push notifications
• C. Smart cards
• D. Physical tokens

Correct answer: B

Explanation

The correct answer is B, as push notifications can be a cost-effective method for implementing MFA, allowing users to confirm their identity through a mobile device. Options A, C, and D involve higher costs due to the need for specialized hardware or software, making them less suitable for a budget-conscious approach.
