Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Entra ID Conditional Access
Microsoft Entra ID Conditional Access. Conditional Access policies enable organizations to enforce MFA based on conditions such as user, location, device state, or risk level. Microsoft Intune compliance policies (Option A) enforce device compliance requirements but do not directly enforce MFA. Microsoft Purview Data Loss Prevention (Option B) focuses on preventing unauthorized sharing of sensitive data, not authentication. Microsoft Defender XDR (Option C) is a threat detection and response solution, not an MFA enforcement tool. Therefore, only Conditional Access (Option D) can enforce MFA for all users.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Microsoft Intune compliance policies
Why it's wrong here
Microsoft Intune compliance policies evaluate device health attributes such as encryption status, jailbreak detection, and minimum OS version, but they do not directly challenge users for multi-factor authentication. While a noncompliant device could be blocked from accessing resources, this is a device-level access control, not an identity-level MFA enforcement mechanism.
- ✗
Microsoft Purview Data Loss Prevention
Why it's wrong here
Microsoft Purview Data Loss Prevention focuses on inspecting and protecting data in transit and at rest, preventing unauthorized sharing or exfiltration of sensitive information. It operates on content and data labels, not on authentication events, so it cannot require users to provide a second proof of identity like MFA.
- ✗
Microsoft Defender XDR
Why it's wrong here
Microsoft Defender XDR is a security analytics and threat response platform that aggregates signals from endpoints, email, and identity to detect and remediate attacks. Its primary function is post-breach detection and automated response; it does not contain features to require or enforce MFA at sign-in time.
- ✓
Microsoft Entra ID Conditional Access
Why this is correct
Microsoft Entra ID Conditional Access is the correct solution because it enables administrators to build granular policies that evaluate sign-in risk, location, device compliance, and user attributes, and then require MFA as one of the access controls. By targeting all users or specific groups, an organization can ensure MFA is enforced for every authentication attempt, satisfying the requirement.
