Sample PL-400 Practice Questions

10 real questions from the free PL-400bank. Pick an answer in your head, then open “Show answer” for the explanation.

1. 1. A developer must implement logic that runs immediately after a record is created, in the same database transaction, so that a related record creation either commits together with the original or rolls back entirely on failure. Which implementation should the developer choose?

   • A. An asynchronous Power Automate flow triggered on record creation
   • B. A canvas app formula in the OnSuccess property
   • C. A cloud flow on a 5-minute recurrence schedule
   • D. A synchronous plug-in registered in the PostOperation stage
   Show answer

   Correct answer: D

   A synchronous plug-in in the PostOperation stage executes within the same database transaction as the triggering operation, so a failure rolls back both records together. A and C run outside the original transaction, and B only affects the client, not the server transaction.

2. 2. A developer is warned that a code component imported from an external source could access security tokens and data when rendered inside a canvas app. What should the developer do before making this component available to makers?

   • A. Review and validate the code component's source before importing and enabling it for makers
   • B. Ignore the warning since code components are sandboxed automatically
   • C. Disable the Power Apps component framework feature entirely in the environment
   • D. Convert the component into a Dataverse plug-in instead
   Show answer

   Correct answer: A

   Because code components run with access to security tokens and data when rendered, administrators and system customizers should review and validate any component before importing it and exposing it to makers. B is false since components are not automatically sandboxed from this risk, C disables a needed platform feature rather than addressing the specific component, and D changes the technology rather than the actual risk.

3. 3. A requirement needs Dataverse to display live pricing data that must always remain in an external SQL Server database and never be duplicated into Dataverse storage. Which table type satisfies this requirement?

   • A. A standard table with a scheduled import job
   • B. An elastic table with a time-to-live column
   • C. A virtual table backed by the SQL Server data provider
   • D. A standard table synchronized nightly through Azure Synapse Link
   Show answer

   Correct answer: C

   A virtual table retrieves data dynamically from the external source at runtime without storing a copy in Dataverse, which matches the requirement exactly. A and D both replicate data into Dataverse storage, and an elastic table (B) still stores its own copy of the data.

4. 4. A requirement states that users must be notified by email when a record's status changes to 'Approved'. Which approach satisfies this requirement using only out-of-the-box functionality?

   • A. A custom plug-in that calls an external SMTP service
   • B. A canvas app screen that users must manually check
   • C. A Dataverse business rule or a no-code Power Automate flow that sends an email on the status change
   • D. A custom connector built specifically for this one notification
   Show answer

   Correct answer: C

   A status-change email notification is a standard trigger-and-action pattern that a no-code Power Automate flow (or a business rule with a workflow) handles without any custom code. A and D introduce custom development for a need the platform already covers, and B requires manual polling instead of a notification.

5. 5. A team is documenting the technical architecture for a new Power Platform solution. Which activity is part of analyzing the technical architecture to identify solution components?

   • A. Writing the final user acceptance test scripts for the solution
   • B. Mapping each business requirement to the Power Platform component (app, flow, plug-in, connector) that will implement it
   • C. Configuring the production environment's backup schedule
   • D. Assigning security roles to individual end users
   Show answer

   Correct answer: B

   Analyzing the technical architecture starts with mapping requirements to the components that will deliver them, which drives every downstream design decision. A is a testing activity, C is an operational task, and D is a security administration task -- none identify solution components.
