Free PL-400 sample questions

3 questions from the free diagnostic, with answers and explanations.

Question 1 · Design the technical architecture

Which requirement is a sign that Fabrikam needs a plug-in rather than out-of-the-box functionality?

  1. Complex validation that must run for every client, including integrations
  2. Hiding a section when a choice changes
  3. Making a column required on every form
  4. Listing open claims in a view sorted by date
Show answer

Answer: A (Complex validation that must run for every client, including integrations)

Logic that must run on the server for every client, and is too complex for business rules, needs a plug-in.

Question 2 · Apply business logic in model-driven apps by using client scripting

In a model-driven app form script, which object should you get from the execution context to read and set column values?

  1. The formContext object
  2. Xrm.Page, which is deprecated
  3. window.document
  4. The global window object
Show answer

Answer: A (The formContext object)

executionContext.getFormContext() returns formContext, which replaces the deprecated Xrm.Page.

Question 3 · Create PCF code components

A PCF component must tell the hosting form that its value changed so that the new value can be saved. Which method does the component call?

  1. notifyOutputChanged
  2. setVisible on the form section
  3. Xrm.Page.data.save from init
  4. A plug-in registered on Update
Show answer

Answer: A (notifyOutputChanged)

notifyOutputChanged tells the framework to call getOutputs and pass the new value to the form.
