Why each option

Microsoft 365 supports several MFA verification methods, including app-based, SMS, and voice call options. This question tests knowledge of which authentication factors are natively supported by Microsoft Entra ID (Azure AD) MFA.

AMicrosoft Authenticate smart phone appCorrect

The Microsoft Authenticator app is a fully supported MFA method in Microsoft 365/Entra ID, providing push notifications, one-time passcodes (TOTP), and passwordless sign-in, making it one of the most secure and recommended options.

Bbiometric retinal scanner

Biometric retinal scanners are not a supported MFA method in Microsoft 365/Entra ID; while Windows Hello for Business supports biometrics (fingerprint/face), retinal scanning is not a natively supported authentication option.

Cverification code sent in a text messageCorrect

SMS text message verification codes are a supported MFA method in Microsoft Entra ID, where a one-time passcode is sent to the user's registered mobile phone number to confirm identity.

Dcustom security question

Custom security questions are not a supported MFA method in Microsoft Entra ID; security questions are only available as an authentication method for Self-Service Password Reset (SSPR), not for MFA step-up verification.

Everification code sent in a phone callCorrect

Phone call verification is a supported MFA method in Microsoft Entra ID, where an automated call is placed to the user's registered phone number and the user presses a key (e.g., #) to approve the sign-in.
