PL-900 Practice Question: Describe the business value of Microsoft Power Platform
A company has a Power Apps portal for external partners to submit support tickets. Partners report that they cannot see the tickets they created. The portal uses Dataverse. What is the most likely cause?
⚠ Common exam trap
Candidates often assume the issue is a network or browser problem, but the PL-900 exam specifically tests understanding that Power Apps portals rely on Dataverse security and entity permissions to control record visibility, not on portal publishing status or browser compatibility.
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
✓
Entity permissions for the ticket table are not configured for portal users.
In Power Apps portals, visibility of Dataverse records is governed by entity permissions, not by the portal being published or the browser used. When partners cannot see tickets they created, the most likely cause is that the entity permissions for the ticket table are not configured to grant 'Read' access to the appropriate portal web roles (e.g., 'Authenticated Users' or a custom role). Without these permissions, the portal cannot query and display the records, even though the data exists in Dataverse.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The partners are using an unsupported browser.
Why it's wrong here
Browser compatibility would cause UI issues but not data access problems.
- ✓
Entity permissions for the ticket table are not configured for portal users.
Why this is correct
Portal users need specific entity permissions to read records; by default, they may not have access.
- ✗
The portal is not published to the external network.
Why it's wrong here
If the portal were not published, partners would not be able to submit tickets at all.
- ✗
The Dataverse environment is in maintenance mode.
Why it's wrong here
Maintenance mode would prevent all operations, not just viewing.
