SC-900 Describe the capabilities of Microsoft Entra Practice Question
This SC-900 practice question tests your understanding of describe the capabilities of microsoft entra. 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 multinational company needs to enforce multi-factor authentication for all users but exclude a break-glass emergency account. Which approach should they take in Microsoft Entra ID?
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 requiring MFA for all users, excluding the break-glass account
Option D is correct because Conditional Access policies in Microsoft Entra ID allow granular control over authentication requirements, including the ability to exclude specific users or groups. By creating a policy that requires multi-factor authentication (MFA) for all users but explicitly excludes the break-glass account, the company ensures security while maintaining emergency access. This approach is more flexible and scalable than per-user MFA or security defaults, which lack the ability to selectively bypass MFA for critical accounts.
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.
✗
Use identity protection to require MFA only for high-risk users
Why it's wrong here
This would not enforce MFA for all users as required.
✗
Enable security defaults and add the break-glass account to a group that bypasses MFA
Why it's wrong here
Security defaults apply to all users and do not support exclusions.
✗
Enable per-user MFA for all users and turn off for the break-glass account
Why it's wrong here
Per-user MFA is a legacy method and not recommended for granular control.
✓
Create a Conditional Access policy requiring MFA for all users, excluding the break-glass account
Why this is correct
Conditional Access allows excluding specific accounts from MFA requirements.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse security defaults with Conditional Access, assuming security defaults can be customized with exclusions, when in fact security defaults are a fixed baseline that cannot be modified to exclude specific accounts.
Detailed technical explanation
How to think about this question
Conditional Access policies are evaluated at authentication time and can include conditions such as user/group membership, location, device state, and application. The exclusion of the break-glass account is achieved by adding it to a group that is explicitly excluded in the policy's 'Users and groups' assignment, ensuring it is never prompted for MFA. This approach also supports 'report-only' mode for testing and integrates with Microsoft Entra ID Protection for additional risk-based controls, making it the enterprise-grade solution for enforcing MFA while preserving emergency access.

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.
