You are troubleshooting a new canvas app.
Users report the app loads slowly. You use the Monitor tool to view various events being performed in the app. Events performed in the app do not have formula details.
You need to enable formulas to be included with the Monitor tool events.
What should you do?

  1. Add the Microsoft Azure Application Insights data source to the canvas app
  2. After each event, implement the trace function within the canvas app
  3. Turn on the Debug published app setting in the canvas app
  4. Validate the Application Insights instrumentation key has been populated in the app object's properties within the canvas app

Answer(s): C

Explanation:

Setting: Debug published app
If you want to view the source expressions in Monitor for the published app, you need to turn on the setting to publish the expressions with the app. This setting is similar to generating a debug file in traditional development. Publishing source expressions with your app is optional. Even when this setting is off, you'll be able to see the events happening in your app, but you won't be able to map these events to specific expressions or formulas.
To enable this setting, go to File > Settings, and then turn on Debug published app.

DRAG DROP (Drag and Drop is not supported)
You are creating a plug-in for a Power Apps app for the human resources department at the company. The app will be used to process new employees and help employees apply for an identification card.

You have the following requirements:
-Applications must not be marked as complete if the employee has not completed mandatory drug screening.
-Add logic that stores the name of the human resources team member that approves an application. This step must be completed before an ID card is created for the applicant.
-Successful validation and ID card printing.

You need to configure the event pipeline.
Select and Place:

  1. See Explanation section for answer.

Answer(s): A

Explanation:



Box 1: PreValidation
Applications must not be marked as complete if the employee has not completed mandatory drug screening.
If you want to change any values for an entity included in the message, you should do it here.
Pre-validation stage executes outside Database Transaction which will not rollback the entire operations written in the plugin if there is any runtime error occurs in one operation. This provides an opportunity to include logic to cancel the operation before the database transaction.

Box 2: PreOperation
Add logic that stores the name of the human resources team member that approves an application. This step must be completed before an ID card is created for the applicant.
Pre-Operation stage executes inside database transaction due to which any runtime error occurs in a single operation in the plugin will rollback entire operations which are part of the plugin.

Box 3: PostOperation
Successful validation and ID card printing.
Post Operation - Plug-ins registered in this stage are executed within the database transaction. Plugin will run after the values have been inserted/changed on the database

DRAG DROP (Drag and Drop is not supported)
You are developing a Power Platform solution. You are modifying a business process flow. You have created a new radial knob for the Total amount value and have added the radial knob to the form.
The Total amount value must be entered at initiation before moving to the next step.
You need to configure the business process flow.

Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Select and Place:

  1. See Explanation section for answer.

Answer(s): A

Explanation:




Step 1: Add another step to the business process flow.
Configure custom controls on a related entity form
In this version of the preview, the easiest way to add custom controls to a BPF is to begin by adding them to a form of the entity that the BPF stage is defined on.
In our example, the Budget Amount and Decision Maker steps of the Qualify stage are defined on the Lead entity. We begin by adding these fields to the Lead main form, and then configure the radial knob and flip switch custom controls for them.

Step 2: Open the business process in the Business Process Flow designer and select Activate/Update.
Generate and export the BPF form
To generate the form for a business process you want to add custom controls to, open the business process in the BPF designer and click on Activate/Update.

Step 3: Copy custom control configurations to the business process flow FormXML for the related entity form.
Copy custom control configurations to the BPF FormXML
To add custom controls to the BPF, we begin by copying the custom control configurations from the Lead entity form that we just exported. To do this, we begin by viewing the FormXML for the Lead entity form, which can be found in the 'customizations' file in the solution zip file.

Step 4: Import the solution into Dataverse.
Import customizations into the CDS (aka Dataverse) environment
Now that we're done making our changes, save the customizations.xml document and add it to the managed solution zip file containing the BPF, replacing the file within it.
Next, import these changes into your CDS environment by going to the Solutions tab in the PowerApps portal and click 'Import'.
