This SC-900 practice question tests your understanding of describe the capabilities of microsoft entra. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 user reports that they cannot access Microsoft 365 apps from a public Wi-Fi network. The admin sees a Conditional Access policy requiring a compliant device and a trusted location. Which component enforces this policy?
Microsoft Entra ID
Why wrong: The identity service, but Conditional Access is the feature.
Microsoft Defender for Cloud Apps
Why wrong: Provides cloud app security, not policy enforcement.
Microsoft Entra Conditional Access
Enforces access policies based on conditions.
Microsoft Intune
Why wrong: Manages device compliance, not policy enforcement.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Microsoft Entra Conditional Access
Microsoft Entra Conditional Access is the policy engine that evaluates conditions (e.g., location, device compliance) and enforces access decisions. When a user attempts to access Microsoft 365 apps, the Conditional Access policy is evaluated by Microsoft Entra ID, which then blocks or grants access based on the policy rules. The policy itself is defined in Microsoft Entra Conditional Access, but the enforcement point is the Microsoft Entra ID authentication and authorization service.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Manages device compliance, not policy enforcement.
Common exam traps
The trap here is that candidates often confuse the policy definition component (Microsoft Entra Conditional Access) with the enforcement component (Microsoft Entra ID), but the question asks for the component that 'enforces' the policy, which is Microsoft Entra ID itself, not the policy configuration interface.
Detailed technical explanation
Conditional Access policies are evaluated during the authentication request to Microsoft Entra ID, which acts as the policy decision point (PDP). The policy conditions (e.g., location via IPv4/IPv6 ranges, device compliance via Intune) are checked, and the resulting access decision (grant, block, or require MFA) is enforced by Microsoft Entra ID at the token issuance step. In a real-world scenario, if a user connects from a public Wi-Fi that is not in the trusted location list, the policy can block access even if the device is compliant, demonstrating the combined condition evaluation.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
