• Question 122:

  DRAG DROP

  You are designing a model-driven app for a company's support desk team.

  You must add a button to the app that creates a reminder task. The button must only display to users if a service case is open for at least seven days.

  You need to define the steps to create the button when App Designer is open.

  In which order should you perform the actions? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

  NOTE: More than one order of answer choices is correct. You will receive credit for any of the correct orders you select.

  Select and Place:

  

  Correct Answer:

  

  Step 1: Edit the command bar.

  Step 2: Add a command button.

  Step 3: Add a data source to the component library

  DataSourceInfo function

  Data sources can provide a wealth of information to optimize the user experience.

  Step 4: Configure a visibility expression.¨

  You can use Power Fx for both actions (what happens when the command button is selected) as well as visibility (logic to control when the button is visible).

  Visible

  Defines logic for hiding or showing the button when running the app.

  To define visibility logic select the command. Then select Visibility on the right command properties pane and choose Show on condition from formula. You may now select Visible on the left of the formula bar then write a Power Fx expression

  using the formula bar.

  Step 5: Create a task by using OnSelect expression.

  OnSelect

  Defines the logic that will be executed when the button is selected within the app.

• Question 123:

  DRAG DROP

  You are creating a Power Apps Component Framework (PCF) control.

  You test the control by using a local test harness.

  You need to complete testing.

  Which commands should you use? To answer, drag the appropriate commands to the correct functions. Each command may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

  NOTE: Each correct selection is worth one point.

  Select and Place:

  

  Correct Answer:

  

  Box 1: start npm start

  Those two “start”-s surrounding the “npm” have completely different meaning. When done this way, a new command prompt window will show up and “npm start” will run in that additional window:

  

  It’ll be the same result – you will have the harness started, but, also, your original terminal session will continue to work, and you won't need to open another one.

  Box 2: Npm start watch

  The following image shows what Visual Studio Code will look like when you use the npm start watch for the DataSetGrid sample:

  

  Launching the test harness in watch mode enables you to quickly see the changes in action. Changes made to any of the following component assets are automatically reflected in the test harness without having to restart it:

  index.ts file.

  Imported modules in index.ts (excluding node_modules).

  All of the resources listed in the ControlManifest.Input.xml file, for example, css/DataSetGrid.css or strings/DataSetGrid.1033.resx

  Incorrect:

  * To start the test harness, you would use the following command:

  npm start

  This is fast and convenient, but this command will lock your terminal session. For example, if you are doing PCF development in Visual Studio Code, here is what you will see in the terminal window:

• Question 124:

  DRAG DROP

  You are creating a Power Platform solution for a fitness studio. Members of the studio will use the solution to track their progress towards fitness goals. Personal trainers create programs with different exercises to match a member's fitness

  level. Members can opt into a program to submit information about their progress with exercises suggested by a trainer.

  Fitness programs and exercises have specific durations, prices, and dates.

  You need to ensure that members can see all of the exercises that a trainer suggests in their calendars.

  What should you use? To answer, drag the appropriate options to the data types. Each option may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

  Select and Place:

  

  Correct Answer:

  

  Box 1: Standard table with User or Team ownership

  Table ownership

  There are two different types of standard and custom table ownership. When you create a custom table the ownership options are User or team or Organization owned. Once a table is created, the ownership type can't be changed.

  Organization - Data belongs to the organization. Access to the data is controlled at the organization level.

  User or team - Data belongs to a user or a team. Actions that can be performed on these rows can be controlled on a user level.

  Note: Tables appear in Power Apps as one of three different types, which indicate how the table came into the environment, whether the table is managed or unmanaged, and whether it can be customized.

  *

  Standard: Several standard tables, also known as out-of-box tables, are included with a Power Platform environment, that includes Microsoft Dataverse. Account, business unit, contact, task, and user tables are examples of standard tables in Dataverse. Most of the standard tables included with Dataverse can be customized. Tables that are imported as part of a managed solution and set as customizable also appear as standard tables. Any user with appropriate privileges can customize these tables where the table property has customizable set to true.

  *

  Managed: Are tables that aren't customizable and have been imported into the environment as part of a managed solution.

  *

  Custom: Custom tables are unmanaged tables that are either imported from an unmanaged solution or are new tables created directly in the environment. Any user with appropriate privileges can fully customize these tables.

  Box 2: Activity table with User or Team ownership Activity tables An activity can be thought of as any action for which an entry can be made on a calendar. An activity has time dimensions (start time, stop time, due date, and duration) that help determine when the action occurred or will occur. Activities also contain data that helps determine what action the activity represents, for example, subject and description. An activity can be opened, canceled, or completed. The completed status of an activity will have several sub-status values associated with it to clarify the way that the activity was completed.

  Activity tables are a special kind of table that can only be owned by a user or team, but can't be owned by an organization. When you create a table, you can specify it as a standard or activity table.

• Question 125:

  DRAG DROP

  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:

  1.

  Applications must not be marked as complete if the employee has not completed mandatory drug screening.

  2.

  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.

  3.

  Successful validation and ID card printing.

  You need to configure the event pipeline.

  In which stage should you register each step.

  To answer, drag the appropriate roles to the correct requirements. Each role may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

  NOTE: Each correct selection is worth one point.

  Select and Place:

  

  Correct Answer:

  

  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

  Correct Answer:

  

  Step 1: Open the app in a browser on the phone.

  Step 2: Add the following text to end of the URL for the app: "andmonitor=true" You can start a Monitor session from a model-driven app. To do this, append andmonitor=true to the end of the URL in the browser. This displays the Monitor

  command on the model-driven app global command bar. Select Monitor to open a monitoring session in a new tab.

  Step 3: Perform the steps to generate the errors and download the results from Monitor.

  Step 4: Open the application in a browser on a laptop computer when they return to the office

• Question 127:

  DRAG DROP

  A company has a Common Data Service (CDS) environment.

  All accounts in the system with a relationship type of Customer set must have an account number. A plug-in has been developed.

  When a Customer is updated with a relationship type, the plug-in sets the account number if not provided by the user.

  You need to register the plug-in.

  Which three 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:

  

  Correct Answer:

  

  Step 1: In the Plug-in Registration tool, select Register New Assembly. You use the Plug-in Registration tool (PRT) to register your plug-in assemblies and steps.

  Registering an assembly is the process of uploading the assembly to the Dataverse database.

  Step 2: In the Plug-in Registration tool, Select Register New Step,..PreOperation PreOperation occurs before the main system operation and within the database transaction.

  If you want to change any values for an entity included in the message, you should do it here.

  Step 3: In the Plug-in Registration tool, Select Register New Image, change the Image type to be a PreImage, and..

  If your plug-in step is registered in the PreValidation or PreOperation stages of the execution pipeline, you could use the Organization service to retrieve the current value of the property, but this is not a good practice for performance. A better

  practice is to define a pre-entity image with your plug-in step registration.

  Box 1: Conditional access You can limit access to users with block access by location to reduce unauthorized access. By using Conditional Access policies, you can apply the right access controls when needed to help keep your organization secure and stay out of your user's way when not needed. Conditional Access analyses signals such as user, device, and location to automate decisions and enforce organizational access policies for resources.

  Box 2: DLP policy DLP policies enforce rules for which connectors can be used together by classifying connectors as either Business or Non-Business. If you put a connector in the Business group, it can only be used with other connectors from that group in

  any given app or flow. Sometimes you might want to block the usage of certain connectors altogether by classifying them as Blocked.

  Box 3: Exfiltration blocking Email exfiltration controls for connectors Microsoft Exchange enables admins to disable email autoforwards and autoreplies to remote domains for external recipients. Exchange does this by using message-type headers, such as Auto Forward received from Outlook and Outlook on web clients.
