Question

A company deploys Microsoft Azure AD. You enable multi-factor authentication. Which of the following methods is NOT a valid multi-factor authentication method in Microsoft 365?

a) Phone call verification.
b) Text message verification.
c) Mobile app verification.
d) CAPTCHA verification.

Answer 1

CAPTCHA verification is not a valid multi-factor authentication method in Microsoft 365. Valid methods include phone call, text message, and mobile app verification.

Step-by-step explanation:

The question is about the valid multi-factor authentication methods provided in Microsoft 365 as part of the security features. Multi-factor authentication (MFA) is an essential security measure that requires users to provide two or more verification factors to gain access to a resource such as an application, online account, or VPN. In Microsoft Azure AD, the valid MFA methods include:

• Phone call verification
• Text message verification
• Mobile app verification (such as using the Microsoft Authenticator app)

However, CAPTCHA verification is not a form of multi-factor authentication used by Microsoft Azure AD. CAPTCHA is typically used to verify that a user is human and not a bot and is not considered a secure method for MFA in Microsoft 365.
