The PL-400 measures your ability to design, build, and troubleshoot Power Platform components that go beyond low-code configuration: custom business logic, system integrations, data conversion, process automation, complex Power Fx formulas, and Power Automate expressions. It's a developer-focused exam, not one for makers or functional consultants.

A team is building five canvas apps that all need the same branded header with a logo, navigation buttons, and consistent styling that non-technical makers should be able to drop onto a screen without writing code. Which approach should the architect recommend?

The official syllabus organized with summaries and progress tracking.
Multi-question scenarios spanning several domains, like the real exam.
The CertifyDeck PL-400 practice test includes 1089+ original exam questions written from the official Microsoft Power Platform Developer skills outline, each with the correct answer explained and available in English and Spanish.
Practice by domain with a free online test, take a timed 100-minute mock exam weighted like the real test and review your mistakes. Start for free, no sign-up or credit card, and try the practice test before deciding.

Built for pro-code developers with hands-on Power Platform experience plus JavaScript, TypeScript, C#, HTML, REST APIs, and Microsoft Azure. Microsoft recommends practical experience building Dataverse plug-ins, PCF components, custom connectors, and Power Automate automations before sitting the exam.
PL-400 tests whether you can move from configuration to development: deciding when to use Power Fx, JavaScript, plug-ins, PCF components, cloud flows, APIs or Azure services. The fastest preparation starts from the official skills outline and turns every objective into a small, testable implementation.
Alternate practice questions by domain with hands-on work in a development environment. After each mistake, classify it: product knowledge, architecture, or a lifecycle detail. That triage makes your review far more efficient than re-reading documentation.
Expect scenario-based questions where several options look plausible and only one satisfies every requirement around Dataverse, security, ALM, integrations, automation, extensibility and performance. The exam mixes single-answer, multiple-choice, hotspot and drag-and-drop items.
Our practice questions follow the same pattern: each one targets a decision, comes with a full explanation of why the other options fail, and is written from the public skills outline rather than copied from any exam dump.
With Power Platform development experience, six weeks are usually enough to organize the syllabus. If you come from a functional background, budget more time for C#, JavaScript, APIs and ALM. Start with a diagnostic quiz, study by domain, and finish with full timed mock exams.
Before booking, make sure you can explain your errors without looking at the answer and check the latest official study guide. The question bank measures progress, but documentation and real implementation are still part of the job.

CertifyDeck is an independent study platform and is not affiliated with, endorsed by, or sponsored by Microsoft. PL-400 and its related marks belong to their respective owner.
Microsoft closes PL-400 registration on 16 October 2026 and, once booked, the exam can be taken through 30 October 2026. From 16 October, registration is only open for AB-400, which earns the same certification (Power Platform Developer Associate) and launches in English only. If you will sit the exam after those dates, prepare AB-400.
Yes — compared with other Power Platform certifications, it's the only exam on the path built entirely around a pro-code profile. Knowing how to use Power Apps or Power Automate as a maker isn't enough — you need real experience writing C# plug-ins, PCF components, custom connectors, and consuming Dataverse APIs.
It depends on your background. If you already work daily with Dataverse and code inside Power Platform, 4-6 weeks of focused review is usually enough. If you're coming from the maker/functional side and need to shore up C#/JavaScript and the platform APIs, planning for 8-12 weeks is more realistic.
The PL-200 (Power Platform Functional Consultant) tests low-code configuration: canvas and model-driven apps, flows, Dataverse from a maker's perspective. The PL-400 assumes you already have that down and focuses on extending the platform with code: plug-ins, integrations, PCF, Azure Functions, and APIs.
Pricing is set by Microsoft based on the country where you take it, and it's paid when you book through Pearson VUE. There's no single global rate, so it's worth checking the exact price during the booking step.
Yes. Microsoft role-based certifications renew every 12 months through a free online assessment on Microsoft Learn — no need to retake the full exam.
Yes. After a first failed attempt you can retake it after 24 hours. If you fail again, Microsoft applies longer waiting periods for subsequent attempts.
Microsoft does not publish an exact number; its exams usually have between 40 and 60 questions and PL-400 gives you 100 minutes. Our timed mock exam mirrors that length and the official domain weights.
You need a scaled score of 700 out of 1000. The scale does not map to a fixed percentage of correct answers, so aim for consistent results above 80% on unseen mock exams before booking.
Yes. You can start for free with no sign-up or card: PL-400 practice questions with explanations, a free online test by domain and published sample questions with answers. Full access to the whole bank and the timed mock exam is a one-off payment.
Yes. Microsoft offers PL-400 in Spanish as well as English. On CertifyDeck every question, option and explanation is available in both languages, keeping the official English terminology.
It is a good free starting point, but it is short and repeats the same items. A practice test with hundreds of original Microsoft Power Platform Developer questions, timed mock exams and practice by domain tells you where you fail and whether you keep the level under time pressure.
No. Dumps are leaked exam questions: using them breaks Microsoft's exam agreement and can void your certification. Our questions are original, written from the official skills outline, and train you to reason through new scenarios instead of memorizing answers.
PL-400 can be booked until 16 October and sat until 30 October 2026; AB-400 is the new Power Platform Developer exam. What changes in the outline, whether your certification still counts, which exam to sit and free practice questions for both.
