PL-900 Power Platform Fundamentals: 320 Practice Questions

Choosing the right Power Platform component is only the beginning. A shared app can still lack data permissions, a successful flow can update the wrong record, and a fluent agent answer can still miss the user's request. These practice questions help you recognize the conditions that make a business solution appropriate and explain why a nearby alternative fails.

Practice against the PL-900 skills measured from July 24, 2026, with 320 original questions across six tests. The scope includes current fundamentals of Dataverse, canvas and model-driven apps, code apps, Plan designer, the vibe experience, cloud and desktop flows, Copilot Studio tools and channels, Microsoft Agent 365, and agent evaluations. Power Pages appears in business-value decisions; this course does not add a separate Power Pages or Power BI exam domain.

Build understanding, then mix the decisions

• Business Value, Dataverse and Governance: 60 questions.
• Power Apps and AI App Creation: 60 questions.
• Power Automate and AI Flow Creation: 60 questions.
• Copilot Studio Agents and Management: 60 questions.
• Mixed Mock 1, Business Constraints: 40 questions in 45 minutes.
• Mixed Mock 2, Changed Conditions: 40 questions in 45 minutes.

Every question includes feedback for each option, an overall explanation, a focused study tip, and Microsoft learning references. The focused tests allow 90 minutes for deliberate practice. The mixed tests interleave domains and use the published domain-weight ranges to help you shift between data, applications, automation, and agents.

Use mistakes as a study plan

1. Work through the focused tests and explain your choice before opening feedback.
2. For each mistake, identify the missing condition: data model, permission, input, workflow outcome, or evaluation criterion.
3. Use the study tip and learning references to review that point.
4. Take a mixed test under the timer, then review the reasoning behind both correct and incorrect choices.

The 40-question mock length and 80% practice target are course settings. They are not Microsoft's fixed exam question count or a conversion of its 700 scaled passing score. This is an independent practice resource, not official Microsoft exam content, an exam dump, or a guarantee of passing. It contains practice tests rather than video lessons or tenant labs. Some AI-assisted product experiences have preview or availability limitations; check current Microsoft documentation before using them operationally.
