PL-400 Practice Test

Microsoft Power Platform Developer

PL-400 tests whether you can actually build production Power Platform solutions — Dataverse plug-ins, custom connectors, PCF components, and Azure integrations — not just configure apps through the maker portal.

Our 500 scenario-based questions cover the full PL-400 blueprint across six domains: creating a technical design (mapping requirements to components, deciding where business logic lives, authentication/authorization strategy, and DLP/security-role impact), building Power Platform solutions (ALM, solution layers, environment variables, and CI/CD with Power Platform Build Tools and Pipelines), implementing Power Apps improvements (complex Power Fx formulas, reusable component libraries, and performance troubleshooting with Monitor), extending the user experience (Client API JavaScript, Dataverse Web API scripting, and PCF component development), extending the platform (Dataverse plug-ins across the execution pipeline, custom APIs, custom connectors, Azure Functions, and Power Automate cloud flow configuration — the largest domain at 30-35%), and developing integrations (publishing and consuming Dataverse events, service endpoints, and data synchronization with change tracking and alternate keys). Every question is grounded against live Microsoft Learn Power Platform developer documentation.

Why Practice with MSCertQuiz?

Microsoft Learn teaches concepts. We prepare you for the actual exam.

1

Deep coverage of the "Extend the platform" domain most question banks underweight despite it being 30-35% of the exam — plug-in execution stages, custom APIs, custom connectors, and Azure Functions integration

2

Real ALM and DevOps scenarios across solution layers, environment variables, Power Platform Pipelines, and Build Tools CI/CD — matching how development teams actually ship Power Platform solutions

3

Full client-scripting and PCF component content most competitors skip: Client API object model, event handler registration, PCF lifecycle events, and component manifests

4

Every question verified against live Microsoft Learn Power Platform developer documentation before it ships, so content stays accurate as the platform keeps evolving

What Our Users Say

“I'd built plenty of canvas apps but never written a Dataverse plug-in from scratch before studying for this. The execution-pipeline and pre/post image questions closed real gaps. Passed on my first attempt.”

VK

Vikram K.

PL-400 Certified

“The custom connector and Azure Functions integration domain was way more detailed than I expected from a practice test, and matched the real exam almost exactly.”

LP

Lucia P.

Power Platform Developer

“As someone who mostly writes client-side JavaScript, the ALM and solution-layer questions filled real gaps between what I knew and what the exam actually tests.”

PL-400 Frequently Asked Questions

Everything you need to know about the PL-400 Power Platform certification

What is PL-400?
PL-400 (Microsoft Power Platform Developer) is a certification validating the ability to design, develop, secure, and troubleshoot Power Platform solutions, including apps, automations, and integrations built on Dataverse, Power Apps, Power Automate, and Azure.
How much does the PL-400 exam cost and how long is it?
The PL-400 exam costs $165 USD, runs approximately 100 minutes, and has a passing score of 700 out of 1000. Confirm current pricing and duration on the official certification page before booking, since exam details can shift alongside Power Platform feature updates.
What is the passing score for PL-400?
The passing score for PL-400 is 700 out of 1000, the same threshold used across nearly all Microsoft role-based certification exams. Scoring is scaled, so 700 represents roughly 70% competency spread across all six exam domains rather than a simple raw percentage.
What topics are covered on PL-400?
PL-400 covers six domains: Create a technical design (10-15%) — architecture and component decisions; Build Power Platform solutions (10-15%) — ALM and CI/CD; Implement Power Apps improvements (10-15%) — canvas app performance and Power Fx; Extend the user experience (10-15%) — client scripting and PCF components; Extend the platform (30-35%, the largest domain) — plug-ins, custom APIs, connectors, and Azure Functions; and Develop integrations (10-15%) — Dataverse events and data synchronization.
How hard is PL-400?
PL-400 is a scenario-heavy, code-adjacent exam that expects real hands-on plug-in and PCF component development experience, not just familiarity with the Power Apps maker portal. Candidates comfortable with low-code app-building often find the plug-in execution pipeline, custom connector authentication, and Azure Functions integration questions the hardest, since they require actual C# and Azure development experience.
How long should I study for PL-400?
Candidates already developing Dataverse plug-ins, custom connectors, or PCF components should plan 4-6 weeks, focused on the Extend the platform domain given its exam weight. Candidates newer to Power Platform development should plan 8-10 weeks. We recommend working through Microsoft Learn's PL-400 learning path first, then practicing with 500 scenario-based questions spread across all six domains in proportion to their exam weight.
What are the prerequisites for PL-400?
There are no enforced prerequisites to register for PL-400, but it is designed for candidates with strong knowledge of Dataverse and hands-on experience developing solutions using Power Apps, Power Automate, plug-ins, custom connectors, and the Dataverse Web API, plus familiarity with Azure services and Application Lifecycle Management practices.
Who should take PL-400?
PL-400 is aimed at developers who build components that extend Power Platform capabilities — code components, plug-ins, integrations, and custom connectors — working alongside functional consultants and business analysts. It pairs well with PL-300 (Power BI Data Analyst) and PL-900 (Power Platform Fundamentals) for candidates building a broader Power Platform credential portfolio.
