The answer is no immediate effect; users who are currently signed in will not be blocked until their next sign-in attempt. This is because Conditional Access policies in Microsoft Entra ID are evaluated only at the moment of authentication—they do not terminate existing sessions or enforce retroactively on already-issued tokens. For the MS-102 exam, this concept tests your understanding of session lifetime and policy enforcement timing, often appearing as a trap where candidates assume a new policy instantly revokes access for signed-in users. A common memory tip is to think of Conditional Access as a bouncer at the door: it checks credentials upon entry, but once someone is inside, the bouncer does not eject them until they try to leave and re-enter. Remember the phrase “next sign-in, not now” to avoid this pitfall on the exam.
MS-102 Deploy and manage a Microsoft 365 tenant Practice Question
This MS-102 practice question tests your understanding of deploy and manage a microsoft 365 tenant. 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.
Exhibit
Refer to the exhibit.

Refer to the exhibit. A Conditional Access policy is created in Microsoft Entra ID. The policy targets the Office 365 app (which includes Exchange Online). You have 1000 users assigned. What is the immediate effect of this policy on users who are currently signed in?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
No immediate effect; users will be blocked on their next sign-in attempt.
Conditional Access policies in Microsoft Entra ID are evaluated at the time of sign-in. They do not terminate existing sessions. Therefore, users who are already signed in will not be affected until their next authentication attempt, at which point the policy's block action will be enforced.
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.
✗
All high-risk users are immediately blocked from accessing email.
Why it's wrong here
Policies are enforced at next sign-in, not immediately.
✓
No immediate effect; users will be blocked on their next sign-in attempt.
Why this is correct
Conditional Access evaluates at sign-in, not real-time.
Related concept
Read the scenario before looking for a memorised answer.
✗
The policy is invalid because the Office 365 app does not support block.
Why it's wrong here
Office 365 supports block grant control.
✗
Only users with a sign-in risk of high are blocked.
Why it's wrong here
The policy uses user risk, not sign-in risk.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Microsoft often tests the misconception that Conditional Access policies apply immediately to active sessions, when in fact they only take effect on the next sign-in attempt unless combined with session controls like sign-in frequency or continuous access evaluation.
Detailed technical explanation
How to think about this question
Conditional Access policies are enforced during the authentication and authorization phase of the sign-in flow, leveraging OpenID Connect and OAuth 2.0 token issuance. Once a user has an active session token, the policy is not re-evaluated until the token expires or the user signs out. This behavior is by design to avoid disrupting productivity, and administrators must use features like 'Sign-in frequency' or 'Continuous access evaluation' to enforce real-time session revocation.
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.
