MS-900 Describe Microsoft 365 apps and services Practice Question
This MS-900 practice question tests your understanding of describe microsoft 365 apps and services. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
```
$TeamsMeetingPolicy = Get-CsTeamsMeetingPolicy -Identity "Global"
$TeamsMeetingPolicy.AllowTranscription = $True
$TeamsMeetingPolicy.AllowRecording = $True
Set-CsTeamsMeetingPolicy -Instance $TeamsMeetingPolicy
```
Refer to the exhibit. A Teams administrator runs the PowerShell commands to enable meeting transcription and recording for all users. After running the commands, users still cannot start transcription in their meetings. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Users may have a custom meeting policy that overrides the global policy.
Option A is correct because in Microsoft Teams, meeting policies are applied hierarchically: a custom policy assigned directly to a user overrides the global policy. Even if the global policy has transcription enabled, users with a custom meeting policy that has AllowTranscription set to False will not be able to start transcription. The admin must either modify the custom policy or assign the global policy to those users.
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.
✓
Users may have a custom meeting policy that overrides the global policy.
Why this is correct
If users have a custom policy, modifying the global policy does not affect them.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The admin does not have the correct permissions.
Why it's wrong here
They were able to run Get-CsTeamsMeetingPolicy, so they likely have permissions.
✗
The admin forgot to run a Grant-CsTeamsMeetingPolicy command.
Why it's wrong here
Grant is needed for per-user assignment, but the global policy applies by default.
✗
The AllowTranscription property is misnamed.
Why it's wrong here
AllowTranscription is a valid property.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume modifying the global policy affects all users, forgetting that a user-assigned custom policy takes precedence and must be explicitly updated or removed.
Detailed technical explanation
How to think about this question
Teams meeting policies are stored in the Microsoft 365 directory and are evaluated at the start of each meeting. The policy precedence is: user-assigned policy > global policy. The Set-CsTeamsMeetingPolicy cmdlet modifies the policy object in the backend, but it does not automatically reapply it to users—users already assigned a custom policy retain that policy until a Grant-CsTeamsMeetingPolicy cmdlet changes their assignment. This is a common oversight when admins assume global policy changes propagate to all users.
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.
