SC-100 Practice Question: Design security operations, identity, and compliance capabilities
This SC-100 practice question tests your understanding of design security operations, identity, and compliance capabilities. 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.
Your organization is implementing a zero-trust security model. You need to design a solution that continuously verifies user identity, device compliance, and access context before granting access to corporate resources. The solution should also support risk-based policies. Which Microsoft security capability should be at the core of this design?
Answer choices
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 is the core policy engine for zero-trust, enabling continuous verification of user identity, device compliance, and access context before granting resource access. It integrates with risk signals from Microsoft Entra ID Protection to enforce risk-based policies, such as requiring multi-factor authentication when sign-in risk is high. This aligns directly with the zero-trust principle of 'never trust, always verify' by evaluating conditions in real time.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Microsoft Intune's device compliance enforcement with the actual policy decision engine, not realizing that Intune provides the device compliance state but Conditional Access is the component that evaluates that state along with identity and risk to make the access decision.
Detailed technical explanation
How to think about this question
Under the hood, Conditional Access evaluates a set of conditions (user/group, location, device platform, client app, sign-in risk, user risk) against a policy that can block access, grant access with session controls (e.g., app-enforced restrictions), or require MFA. It uses the Microsoft Entra ID Protection risk engine, which calculates sign-in risk in real time using machine learning models trained on billions of signals, and user risk based on leaked credentials or anomalous behavior. In a real-world scenario, a user attempting to access SharePoint from an unmanaged device in a high-risk location would trigger a Conditional Access policy requiring MFA and session token lifetime reduction, demonstrating continuous verification.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
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.
