PL-900 Practice Question: Manage the Microsoft Power Platform environment
A university uses Power Apps for student registration. The app is built on Dataverse and shared with all students. Recently, a student reported that they cannot access the app and receive an error that they do not have permission. The app was working earlier. The admin checks the environment and finds that the app's sharing settings have been changed. The admin needs to restore access for all students quickly. What should the admin do?
⚠ Common exam trap
PL-900 often tests whether candidates choose overly complex or inappropriate fixes (support tickets, role escalation, app recreation) when the correct action is simply re-sharing the app with the appropriate security group.
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
✓
Share the app with the 'All Students' security group in the Power Apps maker portal.
Sharing the app with the 'All Students' security group in the Power Apps maker portal restores access for all students quickly and correctly. Security groups are the recommended way to manage access at scale in Dataverse-backed apps.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Contact Microsoft Support to restore the previous sharing settings.
Why it's wrong here
Microsoft Support does not manage per-app sharing entries in a customer environment, so this cannot restore access, and it is far slower than the admin acting directly. It is tempting when settings appear unrecoverable, and would be correct for platform-level faults, not a changed app sharing configuration.
- ✗
Assign the 'Environment Maker' role to all students.
Why it's wrong here
Environment Maker permits creating resources within an environment; it grants no access to the app or its Dataverse tables, so students would still be blocked. It is tempting as a broad environment-level grant, and would be correct for users who must build apps and flows, not consume a shared registration app.
- ✗
Re-create the app from a backup.
Why it's wrong here
Re-creating the app from a backup restores the app definition, not the sharing records that were altered, so students remain without permission. It is tempting as a recovery action, and would be correct if the app itself were corrupted or deleted, not when only its sharing settings changed.
- ✓
Share the app with the 'All Students' security group in the Power Apps maker portal.
Why this is correct
Re-sharing the app with the 'All Students' security group in the Power Apps maker portal restores access for every member at once. Group-based sharing is the quickest route, since the changed sharing settings removed the students' permissions.
