PL-400 is a 100-minute proctored exam (approximately 40-60 items) requiring a 700/1000 scaled score to pass. It covers six skill areas with the heaviest weight on Extend the platform (30-35%), which focuses on Dataverse plug-ins, custom APIs, Web API and Organization service operations, custom connectors, Azure Functions, and Power Automate cloud flows.

Sample PL-400 Practice Questions

Try these sample questions to test your PL-400 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A solution architect needs to choose where to implement a calculation that must run server-side regardless of which client (canvas app, model-driven app, or Web API call) modifies a Dataverse row. Which extension point should the developer recommend?
A.A canvas app Power Fx formula on the OnSelect of a button
B.A synchronous Dataverse plug-in registered on the Update message
C.A JavaScript OnSave handler on the model-driven form
D.A Power Automate cloud flow triggered manually from the app
Explanation: Dataverse plug-ins execute inside the platform event pipeline so they run for every client and API caller. Registering a synchronous plug-in on the Update message guarantees the logic fires regardless of how the row was modified.
2Your team is designing a Dataverse model that must store millions of telemetry rows per day with high write throughput and limited relational queries. Which table type best fits this requirement?
A.Standard table
B.Virtual table
C.Elastic table
D.Activity table
Explanation: Elastic tables are backed by Azure Cosmos DB and are designed for high-volume, high-throughput scenarios with flexible schema and limited relational features compared with standard tables.
3Which Microsoft Power Platform feature should you recommend to prevent makers from combining a connector that accesses HR data with a connector that posts to the public internet within the same flow or app?
A.Security roles
B.Data loss prevention (DLP) policies
C.Field-level security profiles
D.Business units
Explanation: DLP policies classify connectors into Business, Non-Business, and Blocked groups so that connectors in different groups cannot be used together in the same app or flow, preventing unwanted data movement.
4You must surface read-only data from a customer's external SQL system inside a model-driven app, with the data refreshed live and not duplicated in Dataverse. Which design should you choose?
A.Use Power Automate to copy rows nightly into a Dataverse standard table
B.Define a Dataverse virtual table with a virtual table data provider
C.Import the data using the Dataverse Import Wizard
D.Use an elastic table populated by an Azure Function
Explanation: Virtual tables let model-driven apps query external systems through a data provider, so users see live external data inside Dataverse views without storing the rows in Dataverse.
5A canvas app must run a multi-step approval that includes calls to SharePoint and Outlook and must continue if the user closes the app. Where should the long-running orchestration live?
A.Inside the OnSelect of a Power Fx button using Concurrent()
B.In a Power Automate cloud flow called from the canvas app
C.Inside a Dataverse business rule
D.In a synchronous plug-in on Create
Explanation: Cloud flows run in the Power Automate service independent of the app session, so they survive the user closing the canvas app and they natively support SharePoint, Outlook, and approvals connectors.
6A solution requires ALM with separate Development, Test, and Production environments. Which artifact should developers use to move customizations between environments?
A.An unmanaged solution exported and imported in each environment
B.A managed solution deployed through Power Platform Pipelines
C.An Excel export of Dataverse rows
D.A direct database backup and restore
Explanation: Managed solutions are the supported, layered ALM artifact for moving customizations between environments. Power Platform Pipelines automates the export and import with approvals.
7You need a connection string that differs in Dev, Test, and Production but is referenced by the same flow in each environment. Which solution component should you use?
A.A hard-coded value inside the flow
B.An environment variable referenced by the flow
C.A Dataverse column populated per environment
D.A configuration row stored in a custom table queried at runtime
Explanation: Environment variables are solution-aware and can be reassigned per environment without modifying the component definition, which is the recommended ALM approach.
8Your CI pipeline must export an unmanaged solution from the Dev environment, pack it as managed, and import it into Test. Which tool is purpose-built for these tasks in Azure DevOps or GitHub Actions?
A.Plug-in Registration Tool
B.Power Platform Build Tools
C.Configuration Migration Tool
D.XrmToolBox
Explanation: Power Platform Build Tools provide tasks such as Export Solution, Pack Solution, and Import Solution that integrate directly with Azure DevOps and GitHub Actions for CI/CD.
9A managed solution is installed in Production. A bug causes a column requirement level to be wrong and you applied an unmanaged hotfix directly in Production. What is the long-term ALM consequence?
A.The hotfix becomes part of the managed layer automatically
B.The unmanaged customization sits above the managed layer and may mask future managed updates
C.The hotfix is rolled back the next time the environment refreshes
D.Power Platform blocks unmanaged changes in environments containing managed solutions
Explanation: Unmanaged customizations applied directly in Production sit on the active (top) layer and override the managed solution layer, which can hide future managed updates and is considered an anti-pattern.
10Which Dataverse security construct should you use to give a help-desk team read access only to support cases owned within their region without changing the underlying security role?
A.Owner team with shared access via the Share action
B.Access team with an access team template granting Read
C.Field-level security profile
D.Hierarchy security with a manager hierarchy
Explanation: Access teams provisioned by an access team template grant row-level access dynamically to a set of users without altering their security roles, which fits the help-desk regional access scenario.
