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.
A user reports that they are repeatedly prompted for multifactor authentication when accessing Microsoft 365 apps from the same trusted device. What should you do to reduce the number of prompts?
Disable MFA for the user
Why wrong: Disabling MFA weakens security.
Change the user's MFA method to text message
Why wrong: Changing method doesn't reduce prompt frequency.
Configure 'Remember MFA' settings in Conditional Access
Remember MFA allows trusted sessions for a set period.
Reset the user's MFA registration
Why wrong: Resetting would require re-registration, increasing prompts.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Configure 'Remember MFA' settings in Conditional Access
Option C is correct because the 'Remember MFA' setting in Conditional Access allows administrators to configure the session lifetime for MFA prompts on trusted devices. By extending the 'MFA reauthentication frequency' or enabling 'Remember Multifactor Authentication' for a longer period (e.g., 30 days), users will not be repeatedly challenged on the same device, reducing friction while maintaining security.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Disable MFA for the user

Change the user's MFA method to text message
Why it's wrong here
Changing method doesn't reduce prompt frequency.
Configure 'Remember MFA' settings in Conditional Access
Why this is correct
Remember MFA allows trusted sessions for a set period.

Reset the user's MFA registration
Why it's wrong here
Resetting would require re-registration, increasing prompts.
Common exam traps
The trap here is that candidates often confuse 'changing the MFA method' (Option B) with reducing prompt frequency, not realizing that the method type has no impact on how often the prompt appears—only the session persistence settings control that.
Detailed technical explanation
Under the hood, the 'Remember MFA' setting works by issuing a persistent browser cookie or token (e.g., a session token with a configurable lifetime) that the Microsoft Entra authentication service honors to skip MFA challenges. In Conditional Access, the 'Session' control allows administrators to set the 'Sign-in frequency' and 'Persistent browser session' values; for MFA specifically, the 'Remember Multifactor Authentication' setting in the legacy MFA portal (or the equivalent in Entra) controls the number of days a device is trusted before re-prompting. A real-world scenario is a corporate device used daily—setting this to 30 days eliminates daily MFA prompts while still requiring re-authentication after the period expires or if the device is lost.
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.
