Microsoft 365 Fundamentals — Question 33

A company deploys Microsoft Azure AD. You enable multi-factor authentication.
You need to inform users about the multi-factor authentication methods that they can use.
Which of the following methods is NOT a valid multi-factor authentication method in Microsoft 365?

Answer options

• A. Receive an automated call on the desk phone that includes a verification code
• B. Insert a small card in to a desktop computer and provide a PIN code when prompted
• C. Receive a call on a mobile phone and select the pound sign (#) when prompted
• D. Receive an SMS text message that includes a verification code

Correct answer: B

Explanation

The correct answer is B because using a physical card in a desktop computer for authentication is not supported by Microsoft 365's multi-factor authentication methods. Options A, C, and D are all valid methods as they utilize phone calls and text messages, which are accepted forms of multi-factor authentication.
