PL-900 Practice Question: Describe the business value of Microsoft Power Platform
Your organization wants to create a public-facing website where customers can submit support requests. The website should be built with minimal custom code and integrate with Dataverse. Which Power Platform component should you use?
⚠ Common exam trap
A common mix-up: candidates confuse Power Apps (which also uses Dataverse) with Power Pages, not realizing that Power Apps requires user authentication and is not designed for anonymous public-facing websites, whereas Power Pages is explicitly built for external portals.
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
Power Pages is the correct choice because it is a low-code, secure, enterprise-grade platform for creating public-facing websites that integrate directly with Dataverse. It enables external customers to submit support requests without custom code, leveraging built-in authentication, form components, and Dataverse data binding.
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 Pages
Why this is correct
Power Pages provides a low-code, external-facing portal that authenticates and stores customer submissions directly in Dataverse, satisfying the public website and minimal custom code constraints. Unlike model-driven apps, which require internal licensing, or canvas apps, which lack anonymous public access, Power Pages is purpose-built for external users.
- ✗
Power BI
Why it's wrong here
Power BI visualises and reports on data; it provides no data-entry surface for customers to submit requests. It is tempting because it connects directly to Dataverse for analytics, and would be correct if the requirement were dashboards reporting on existing support-request volumes rather than capturing new submissions.
- ✗
Power Apps
Why it's wrong here
Power Apps builds internal canvas or model-driven apps requiring authenticated users, not anonymous public web forms. It is tempting because it integrates natively with Dataverse and needs little code, and would be the right choice for an internal support app used by employees rather than external customers.
- ✗
Power Automate
Why it's wrong here
Power Automate orchestrates flows triggered by events, so it cannot host a customer-facing submission page; Dataverse integration is downstream of the form. It is tempting because flows can create Dataverse rows from a submission, and would be correct for automating approvals or notifications after the request is captured.
