PL-900 Practice Question: Building a public-facing portal to allow…
A company is building a public-facing portal to allow customers to submit support tickets and track their status. The portal must support anonymous browsing for ticket submission but require authentication to view ticket details. Which Power Pages feature should they use?
⚠ Common exam trap
PL-900 often tests the confusion between table permissions (data/row-level access) and page permissions with web roles (page-level access) — candidates pick table permissions for a page-authentication requirement.
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
✓
Page permissions with anonymous and authenticated web roles
Power Pages uses web roles combined with page permissions and table permissions to control access. Assigning an anonymous web role to public pages lets unauthenticated users submit tickets, while an authenticated web role on ticket-detail pages enforces sign-in before viewing details.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Power Automate flows triggered by page visits
Why it's wrong here
Power Automate flows respond to events such as record creation, not page-level authorisation; they cannot gate ticket details behind sign-in. It is tempting because flows automate portal behaviour, and they would be correct for triggering notifications or ticket routing after submission.
- ✗
Microsoft Customer Voice
Why it's wrong here
Microsoft Customer Voice collects survey feedback and cannot enforce authentication on ticket pages. It is tempting because it is a customer-facing portal component, and it would be correct had the requirement been gathering satisfaction ratings after ticket resolution rather than controlling access to ticket details.
- ✗
Dataverse table permissions
Why it's wrong here
Table permissions govern row-level access to Dataverse records once a user is authenticated; they cannot themselves permit anonymous browsing. They are the right tool for restricting which contact sees which ticket, but the stem's anonymous-submission requirement needs web roles and page-level access settings instead.
- ✓
Page permissions with anonymous and authenticated web roles
Why this is correct
Page permissions combined with anonymous and authenticated web roles let unauthenticated visitors submit tickets while restricting ticket detail views to signed-in users. This satisfies both the anonymous submission requirement and the authentication requirement for viewing ticket details.
