CompTIA Security+ (SY0-601) — Question 632

A company is currently utilizing usernames and passwords, and it wants to integrate an MFA method that is seamless, can integrate easily into a user’s workflow, and can utilize employee-owned devices. Which of the following will meet these requirements?

Answer options

• A. Push notifications
• B. Phone call
• C. Smart card
• D. Offline backup codes

Correct answer: A

Explanation

Push notifications are an effective MFA method because they are easy to integrate into a user's workflow and can be received on personal devices. In contrast, phone calls can be disruptive, smart cards require specific hardware that may not be employee-owned, and offline backup codes can be cumbersome and less convenient for everyday use.
