PL 400 content outline and where to practise each area

The content areas below are copied from the official PL 400 content outline published by Microsoft. The right-hand column shows which of our practice sets covers it.

Worked examples: how to reason through PL 400 questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: When a PL 400 professional encounters an unexpected result during a technical procedure, the FIRST action should be to:

1. Continue the procedure and address it later
2. Stop, assess the situation, and determine whether to proceed or seek guidance
3. Repeat the procedure from the beginning immediately
4. Report the issue without any preliminary assessment

Answer: B. Stop, assess the situation, and determine whether to proceed or seek guidance

Explanation:

B is correct. When a result surprises you, stop and work out what happened before you do anything else. On a real Power Platform project, that means checking logs, plug-in trace output or flow run history before you touch production data.

• A is wrong because carrying on can spread the problem, for example by writing bad records to Dataverse.
• C is wrong because running the procedure again without knowing the cause may just repeat the failure.
• D is wrong because a report with no assessment leaves out the facts others need to act on it.

Rule to remember: when you see a FIRST-action question, the best answer is usually to stop and gather information before acting.

Example 2

Question: What step is essential in Power App creation 2?

1. Skip UI setup
2. Essential design step 2
3. Avoid connectors
4. Ignore logic

Answer: B. Essential design step 2

Explanation:

B is correct, but this is a weak question. Its wording is vague, and you will not see anything like it on the real exam. We have flagged it for rewriting. B wins only because it is the one option that tells you to do a design step instead of skipping something.

• A is wrong because the screens and controls are how users work with a canvas app, so you cannot skip the UI setup.
• C is wrong because connectors are how an app reads and writes data in sources such as Dataverse or SharePoint.
• D is wrong because Power Fx formulas hold the app's behaviour, so ignoring logic leaves you with an empty shell.

Rule to remember: a working app needs a planned UI, data connections and logic. Expect real questions to name a specific control, formula or connector.

Example 3

Question: What is the PRIMARY purpose of obtaining PL 400 certification in Microsoft Certified Power Platform Developer Associate?

1. To satisfy a personal achievement goal
2. To demonstrate verified competency and adherence to professional standards
3. To guarantee employment in the field
4. To bypass educational requirements

Answer: B. To demonstrate verified competency and adherence to professional standards

Explanation:

B is correct. A certification shows that an independent assessment has checked your skills against a published standard. That is why employers and clients pay attention to it.

• A is wrong because personal satisfaction may be a bonus, but it is not the main reason a credential exists.
• C is wrong because no certification can promise you a job. Hiring depends on many other factors.
• D is wrong because a certification does not replace education. It sits alongside experience and training.

Rule to remember: in questions about why something exists, options with absolute words such as guarantee or bypass are rarely correct. The answer that describes verified, measurable value usually is.

How to use these practice tests

Start by checking which exam you will sit. PL-400 testing ends on October 30, 2026. If you cannot sit it by then, compare the official AB-400 page with the PL-400 skills outline before you plan further study.

1. Take a baseline test. Do the full practice test without notes. Note which topics you miss most, not just your total.
2. Study your weakest areas first. For each weak area, read the matching Microsoft Learn module, then do the topic set right away. Good starting points are Plugin Development, Custom Connectors and PCF Controls.
3. Build things. In a developer environment, register a plug-in step, call the Dataverse Web API, and package a solution. Then try the ALM and Deployment set. Code questions are easier once you have seen the error messages for yourself.
4. Review every miss. For each wrong answer, write down why the right option is right and why you chose the wrong one.
5. Practise against the clock. Retake the full test with a 100-minute timer and aim well above 700 on the 1–1,000 scale.

Our questions are practice material written with AI tools. They are not real exam questions. Use Microsoft's official skills outline as your final checklist.
