PL-900 Practice Question: Describe the business value of Microsoft Power Platform
A real estate agency wants to provide a portal where tenants can submit maintenance requests online. The portal should allow tenants to track the status of their requests. The agency staff should be able to update the status and assign work orders to contractors. The agency uses Microsoft 365 and has Power Platform licenses. What should they use?
⚠ Common exam trap
Many candidates confuse Power Apps canvas apps (for internal users) with Power Pages (for external users), and overlook that Dataverse is the required common data platform for both the portal and the staff app.
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
✓
Power Pages for tenants, Dataverse for storage, Power Automate for notifications, and Power Apps model-driven app for staff
It uses Power Pages to create an external-facing portal for tenants to submit and track maintenance requests, Dataverse as the underlying data store for all request data, Power Automate to send notifications (e.g., status updates), and a Power Apps model-driven app for staff to manage requests and assign work orders. This combination provides a secure, low-code solution that leverages the existing Microsoft 365 and Power Platform licenses.
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 Apps canvas app for tenants and Power Apps model-driven app for staff
Why it's wrong here
A canvas app for tenants and a model-driven app for staff both require licensing and separate builds, whereas the requirement is an external-facing portal with tracking. This suits internal app scenarios where users hold Power Apps licences, not anonymous tenant access.
- ✗
AI Builder and Power Automate to process requests
Why it's wrong here
AI Builder and Power Automate process or route requests but provide no tenant-facing submission interface or status tracking, and no work-order assignment for staff. This suits automating document extraction or approval flows once a request already exists in a data source.
- ✗
Power BI dashboard for tenants to view status and Power Apps for staff
Why it's wrong here
Power BI renders read-only reports, so tenants cannot submit requests, and it cannot update status or assign work orders. This combination suits staff analytics and reporting over existing maintenance data, not a transactional portal with write access.
- ✓
Power Pages for tenants, Dataverse for storage, Power Automate for notifications, and Power Apps model-driven app for staff
Why this is correct
Power Pages provides the external tenant-facing portal, Dataverse stores requests and work orders relationally, Power Automate sends status notifications, and a model-driven app gives staff a forms-and-views interface over the same Dataverse tables, satisfying tracking and assignment requirements within existing licences.
