The correct answer is Power Pages for tenants, Dataverse for storage, Power Automate for notifications, and a Power Apps model-driven app for staff. This combination works because Power Pages is specifically designed to create secure, external-facing portals—ideal for a tenant maintenance request portal—while Dataverse provides a unified, relational data store that tracks request status and work orders. Power Automate handles automated notifications when statuses change, and the model-driven app gives staff a role-based interface to update records and assign tasks. On the PL-900 exam, this scenario tests your understanding of how Power Platform components complement each other for external vs. internal users; a common trap is choosing SharePoint for storage instead of Dataverse, but Dataverse is required for relational data and Power Pages integration. Remember the memory tip: “Tenants see Pages, staff see Apps, data lives in Dataverse, and flows send the alerts.”

This PL-900 practice question tests your understanding of describe the business value of microsoft power platform. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
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
Option D is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often 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.
Detailed technical explanation
How to think about this question
Power Pages (formerly Power Apps portals) uses Dataverse as its backend, allowing external users to authenticate via Azure AD B2C or local authentication, and provides role-based access control. The model-driven app for staff leverages Dataverse's business rules, workflows, and security roles to enforce status transitions and work order assignments. Power Automate can trigger notifications based on Dataverse record changes, such as when a request status is updated to 'Assigned'.

Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
