- A
Grant control 'Require multi-factor authentication'
Why wrong: Requiring MFA forces additional verification but does not enforce a specific re-authentication interval. The user could satisfy MFA once and maintain the session for longer than 4 hours if session lifetime allows.
- B
Session control 'Sign-in frequency'
Correct. The sign-in frequency session control allows administrators to set the time interval after which a user must re-authenticate, even if the session is still active.
- C
Session control 'Persistent browser session'
Why wrong: Persistent browser session controls whether users can stay signed in after closing their browser, but it does not enforce re-authentication at a set interval during an active session.
- D
Grant control 'Require device to be marked as compliant'
Why wrong: Requiring a compliant device checks device health but does not control how often the user must re-authenticate. The session can continue as long as the device remains compliant.
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. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
An organization uses Microsoft Entra ID and wants to require users to re-authenticate every 4 hours when accessing a critical financial application, even if the user already has an active sign-in session. Which Conditional Access control should be configured?
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
Session control 'Sign-in frequency'
The 'Sign-in frequency' session control in Conditional Access allows administrators to specify the time interval after which a user must re-authenticate, even if they have an active session. By setting this to 4 hours, the organization ensures that users re-authenticate before accessing the critical financial application, overriding any existing session tokens.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Grant control 'Require multi-factor authentication'
Why it's wrong here
Requiring MFA forces additional verification but does not enforce a specific re-authentication interval. The user could satisfy MFA once and maintain the session for longer than 4 hours if session lifetime allows.
- ✓
Session control 'Sign-in frequency'
Why this is correct
Correct. The sign-in frequency session control allows administrators to set the time interval after which a user must re-authenticate, even if the session is still active.

Grant control 'Require device to be marked as compliant'
Why it's wrong here
Requiring a compliant device checks device health but does not control how often the user must re-authenticate. The session can continue as long as the device remains compliant.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing session controls (which manage token lifetime and re-authentication behavior) with grant controls (which enforce conditions at initial sign-in), leading candidates to select 'Require multi-factor authentication' thinking it will force periodic re-authentication.
Detailed technical explanation
How to think about this question
Sign-in frequency works by issuing a new primary refresh token (PRT) with a configurable lifetime, and the Conditional Access policy enforces re-authentication by invalidating the existing session token after the specified interval. Under the hood, this leverages the OAuth 2.0 refresh token rotation mechanism, where the client must re-authenticate to obtain a new PRT when the sign-in frequency period expires. In real-world scenarios, this is critical for high-security applications like financial systems, where continuous session validity could expose sensitive data if a device is compromised.
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.
