Quick Answer
The answer is to configure Authentication Session Management within a Conditional Access policy. This is correct because it directly addresses the need to minimize MFA prompts by allowing you to set a specific sign-in frequency, such as requiring reauthentication every 24 hours, or enabling a persistent browser session that remembers MFA for up to 14 days. On the Microsoft 365 Administrator MS-102 exam, this scenario tests your understanding of balancing security with user experience, often appearing as a trap where candidates mistakenly choose "Remember MFA for trusted devices" in the MFA service settings, which is a legacy control. The key distinction is that Authentication Session Management is a Conditional Access policy setting that provides granular control over session lifetime, while the legacy setting is less flexible and can be overridden by modern policies. A helpful memory tip: think of "Session Management" as the "snooze button" for MFA—it lets you set how long users can stay authenticated before being prompted again, keeping security tight without annoying users.
This MS-102 practice question tests your understanding of implement and manage microsoft entra identity and access. 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.
Your company has a Microsoft 365 E5 subscription and uses Microsoft Entra ID. Users report that they are frequently prompted for multi-factor authentication (MFA) even after signing in successfully. You want to minimize these prompts while maintaining security. What should you configure?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Configure Authentication Session Management
This controls sign-in frequency and token lifetime, reducing prompts.
Modify the Conditional Access policy to require MFA for all apps
Why wrong: This would increase MFA prompts, not reduce them.
Change the per-user MFA state to Disabled
Why wrong: Disabling MFA would reduce security.
Adjust Identity Protection user risk policy
Why wrong: Risk policy does not control session lifetime.

Correct answer & explanation
Configure Authentication Session Management
Option A is correct because configuring Authentication Session Management in a Conditional Access policy allows you to control how often users are prompted for MFA by setting the sign-in frequency (e.g., every 24 hours) or persistent browser session (e.g., 'Remember MFA for 14 days'). This directly addresses the user complaint of frequent MFA prompts while maintaining security by enforcing reauthentication at defined intervals.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Modify the Conditional Access policy to require MFA for all apps
Why it's wrong here
This would increase MFA prompts, not reduce them.
Change the per-user MFA state to Disabled
Why it's wrong here
Disabling MFA would reduce security.
Adjust Identity Protection user risk policy
Why it's wrong here
Risk policy does not control session lifetime.
Common exam traps
The trap here is that candidates confuse session controls (which manage MFA prompt frequency) with risk-based policies or per-user MFA states, assuming that disabling MFA or modifying risk policies will reduce prompts, when in fact session management is the precise control for this scenario.
Detailed technical explanation
Authentication Session Management leverages the 'Keep me signed in' (KMSI) and sign-in frequency controls, which are enforced via the Primary Refresh Token (PRT) lifetime in Microsoft Entra ID. The PRT is a JWT token that, when configured with a session control, sets the Max Age attribute to limit how long a session is valid before requiring reauthentication. In real-world scenarios, organizations often set sign-in frequency to 24 hours for low-risk apps and 1 hour for sensitive apps, balancing security and user experience.
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.
