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. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 needs to enforce multi-factor authentication (MFA) for all users accessing Microsoft Entra ID integrated applications. However, users in the finance department should be exempted from MFA when accessing a specific legacy financial app that does not support modern authentication. What should you design?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a Conditional Access policy that requires MFA for all cloud apps except the legacy app
Option B is correct because Conditional Access policies allow granular control, including exemption for specific applications. Option A is wrong because security defaults would apply MFA to all users and apps with no exemption. Option C is wrong because per-user MFA is outdated and does not offer app-based exemptions. Option D is wrong because Identity Protection is for risk-based policies, not app exemptions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Enable security defaults for all users
Why it's wrong here
Security defaults enforce MFA for all users, with no ability to exempt specific apps.
✗
Enable per-user MFA and exclude the finance department
Why it's wrong here
Per-user MFA does not support application-level exemptions; it is also deprecated in favor of Conditional Access.
✗
Use Microsoft Entra Identity Protection to require MFA based on risk
Why it's wrong here
Identity Protection can require MFA for risky sign-ins but cannot provide a blanket exemption for a specific app.
✓
Create a Conditional Access policy that requires MFA for all cloud apps except the legacy app
Why this is correct
Conditional Access policy can be scoped to exclude specific applications, allowing the finance department to access the legacy app without MFA.

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.
