PL-900 Web Role Permissions Practice Question

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
✓
The user's web role lacks 'Create' permission on the Dataverse table
The user is authenticated and can see the form, but the form's 'Create' permission is set to 'Authenticated Users'. However, the underlying Dataverse table requires that the user's specific web role have the 'Create' permission assigned. Even though the form permission allows Authenticated Users, if the user's web role does not have 'Create' on the table, the submission will fail. Option A is incorrect because JavaScript errors would not cause a permission-related submission failure. Option C is incorrect because the page is already accessible. Option D is incorrect because the user is authenticated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
JavaScript error on the form
Why it's wrong here
JavaScript errors might prevent submission but are not specific to permissions.
- ✓
The user's web role lacks 'Create' permission on the Dataverse table
Why this is correct
Form permissions rely on table permissions; the role may not have create rights.
- ✗
Page permission is set to 'Authenticated Users' but the page is already accessible
Why it's wrong here
The page is visible, so page permission is not the issue.
- ✗
The user is not logged in
Why it's wrong here
The user is authenticated as stated.
