The answer is multi-factor authentication, as it directly addresses the need for a second form of verification beyond just a password. This identity feature enhances security by requiring an additional factor—such as a phone call, app notification, or biometric—before granting access to sensitive resources like SharePoint Online financial data. On the SC-900 exam, this question tests your understanding that multi-factor authentication enforcement is the core security mechanism, while Conditional Access is the policy tool that can require MFA, not the verification method itself. A common trap is confusing the policy engine (Conditional Access) with the actual authentication requirement; remember that MFA is the "what" and Conditional Access is the "how" to enforce it. For a quick memory tip, think of MFA as the "second lock on the door" that directly provides the extra verification step, making it the correct choice whenever the question asks for a method requiring a second form of verification.
SC-900 Practice Question: Describe the concepts of security, compliance, and identity
This SC-900 practice question tests your understanding of describe the concepts of security, compliance, and identity. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants to ensure that only authorized users can access sensitive financial data stored in Microsoft SharePoint Online. Which identity feature should they use to require a second form of verification?
Why wrong: Microsoft Authenticator is an MFA method, but the question asks for the feature that requires a second form of verification, which is MFA itself.
B
Self-service password reset
Why wrong: SSPR allows users to reset their own passwords but does not provide a second verification factor.
C
Conditional Access
Why wrong: Conditional Access is a policy engine that can enforce MFA but is not itself a verification method.
D
Multi-factor authentication
MFA requires a second form of verification, such as a phone call or app notification.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Multi-factor authentication
Multi-factor authentication (MFA) is the correct answer because it requires a second form of verification, such as a phone call or app notification, in addition to a password. Conditional Access is a policy engine that can enforce MFA but is not itself a verification method. Self-service password reset and Microsoft Authenticator are features that support MFA but are not the overarching concept.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
