AB-400 dumps are already being advertised across dumps vendors — but here is the problem: AB-400 (Extending Microsoft Power Platform Solutions with Code and AI) goes live October 16, 2026, and almost every site selling AB-400 exam dumps has zero real questions. They list the code with 0 Q&As, placeholder prices, or "Preorder" pages while selling recycled PL-400 material that misses the new exam entirely. This guide explains what AB-400 dumps really are, how the new exam differs from PL-400, and the preparation material that actually matches the Microsoft Certified: Power Platform Developer Associate certification.

What are AB-400 dumps?

  • AB-400 dumps are files containing questions and answers collected from the new Extending Microsoft Power Platform Solutions with Code and AI exam.
  • Vendors sell these PDF or web-based files for roughly $25 to $99 USD — though most currently list AB-400 with no actual content.
  • They claim to show you the real format of the exam questions for the Power Platform Developer Associate certification.
  • In practice, today's AB-400 exam dumps pages are mostly shells: competitors show 0 Q&As, $888 placeholder prices, or "Preorder" listings with nothing to download.
  • Some vendors relist old PL-400 content under the AB-400 name — six retired domains repackaged as the new four-domain exam.

What the new AB-400 exam actually tests

AB-400 is Extending Microsoft Power Platform Solutions with Code and AI, and its four reworked domains set it apart from PL-400:

  • Extending with code — plug-ins, custom connectors, and solution components built by a developer, not a maker.
  • Agentic AI in solutions — agents as part of solution logic, a domain that did not exist under PL-400.
  • Copilot Studio integration — building and extending copilots that ship inside business solutions.
  • Power Fx, Python, and YAML — formula language, Python in solution logic, and YAML definitions for configuration as code, plus Microsoft Foundry model integration.

Six old domains became four new ones. Any AB-400 dumps page that cannot name these domains is selling the old exam.

What the competitor research uncovered

Ten top-ranking AB-400 dumps and exam-dumps pages were analyzed fresh for this article. The landscape is remarkable: every dumps vendor lists the code but none has real AB-400 questions. One lists 0 Q&As with a nonsensical $888 price placeholder. Another admits AB-400 is on "Preorder" while its PL-400 bank holds 405 questions from 2023-era content. Search results are polluted by AZ-400 (Azure DevOps) dumps pages — a different exam entirely. Only one editorial page covers the PL-400 to AB-400 transition accurately, and it offers zero practice questions. This article fills every one of those gaps with real, verifiable facts.

Not AZ-400: clearing up the confusion

Searchers looking for AB-400 exam dumps routinely land on AZ-400 dumps pages. These are different exams: AZ-400 is Designing and Implementing Microsoft DevOps Solutions for Azure DevOps. AB-400 is Extending Microsoft Power Platform Solutions with Code and AI, the developer associate exam for Power Platform, leading to Microsoft Certified: Power Platform Developer Associate. If the page you found talks about pipelines and Azure Repos, you are studying the wrong exam.

The PL-400 to AB-400 transition you must know

Microsoft's timeline is public: PL-400 testing ends October 15, 2026, and AB-400 goes live October 16, 2026. Six domains became four, and the new blueprint assumes agentic AI as part of solution logic. The new skills — Power Fx formulas, Python in solution logic, YAML definitions, Microsoft Foundry model integration, and Copilot Studio agents — appear nowhere in any PL-400-era question bank. Any AB-400 dumps page that cannot name these domains is selling you the old exam.

The preparation that matches the new exam

Prepare with expert-written practice questions built for the current AB-400 blueprint. Good practice material tests the same judgment the exam tests — choosing when to extend with code versus Power Fx, when an agent belongs in the solution, how Foundry models integrate — with full explanations for every option. You build real skill and walk in prepared for the questions AB-400 actually asks.

The questions that actually target AB-400

Because no dumps vendor has real AB-400 questions, your best move is practice material written specifically for the October 2026 blueprint. The CertsHouse AB-400 preparation set delivers exactly that: 71 expert-verified questions for Extending Microsoft Power Platform Solutions with Code and AI, refreshed September 23, 2026, a printable PDF with the free web-based practice engine included within 24 hours, a free demo to try first, and a cashback guarantee. Rated 4.88 out of 5 and currently $45 down from $65 with coupon Save25, it is the up-to-date path to the Microsoft Certified: Power Platform Developer Associate certification.
