  Correct Answer:

  

  The ClearCollect function deletes all the records from a collection.

  Syntax: ClearCollect( Collection, Item, ... )

  Collection Required. The collection that you want to clear and then add data to. Item(s) - Required. One or more records or tables to add to the data source.

  Box 1: Yes

  The Patch function in Power Apps modifies or creates one or more records in a data source, or merges records outside of a data source. Use Patch with the Defaults function to create records.

  Box 2: No

  The return value of Patch is the record that you modified or created. If you created a record, the return value may include properties that the data source generated automatically. However, the return value doesn't provide a value for fields of a

  related table.

  For example, you use Set(MyAccount, Patch(Accounts, First(Account), 'Account Name':

  "Example name"); and then MyAccount.'Primary Contact'.'Full Name'. You can't yield a full name in this case. Instead, to access the fields of a related table, use a separate lookup such as:

  LookUp(Accounts, Account = MyAccount.Account).'Primary Contact'.'Full Name

  Box 3: Yes

  Box 4: Yes

  Merge records outside of a data source.

  Specify two or more records that you want to merge. Records are processed in the order from the beginning of the argument list to the end, with later property values overriding earlier ones.

  Patch returns the merged record and doesn't modify its arguments or records in any data sources.

• Question 73:

  HOTSPOT

  You have a model-driven app that uses the Common Data Service (CDS). You create three custom entities that are in many-to-one parental relationships with the Account entity.

  Box 1: Site Map validation

  When you validate the app, the app designer canvas shows you details about the assets that are missing.

  In the app designer, select Validate.

  A notification bar appears and shows you whether the app has any errors or warnings. The notification bar shows warnings in cases where, for example, an entity has no forms or views, or the app doesn't contain any components. An error

  might appear if a site map isn't configured for the app.

  

• Question 75:

  HOTSPOT

  You are developing an app for a sales team to record contact details in their Common Data Service (CDS) database.

  The app must handle loss of network and save the data to CDS when reconnected.

  The main screen of the app has a form to collect contact data and a button. The OnSelect property for the button has the following expression:

  

  For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.

  Correct Answer:

  

  Box 1: Yes LoadData and SaveData combine to form a simple mechanism to store small amounts of data on a local device. By using these functions, you can add simple offline capabilities to your app. Box 2: No Box 3: No Box 4: Yes

• Question 76:

  HOTSPOT

  A company imports data from files.

  The following code is created to import the files. (Line numbers are included for reference only.)

  

  For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.

  Hot Area:

  

  Correct Answer:

  

  Box 1: No

  Need to set ContinueOnError=True. ContinueOnError: When true, continue processing the next request in the collection even if a fault has been returned from processing the current request in the collection. When false, do not continue

  processing the next request.

  Box 2: No

  ContinueOnError = true must be added before Requests = new OrganizationRequestCollection() on line 3.

  Example:

  // Create an ExecuteMultipleRequest object.

  requestWithResults = new ExecuteMultipleRequest() {

  // Assign settings that define execution behavior: continue on error, return responses.

  Settings = new ExecuteMultipleSettings()

  {

  ContinueOnError = false,

  ReturnResponses = true

  },

  // Create an empty organization request collection.

  Requests = new OrganizationRequestCollection()

  };

  Box 3: Yes

  You can use the ExecuteMultipleRequest message to support higher throughput bulk message passing scenarios in Common Data Service. ExecuteMultipleRequest accepts an input collection of message Requests, executes each of the

  message requests in the order they appear in the input collection, and optionally returns a collection of Responses containing each message's response or the error that occurred.

  Box 4: No

  This is just for displaying the result.

  Box 1: Configure entity relationship

  Box 2: Configure entity change tracking The change tracking feature in Microsoft Dataverse provides a way to keep the data synchronized in an efficient manner by detecting what data has changed since the data was initially extracted or last synchronized. Previously, without this new feature, it was difficult to build a reliable and efficient mechanism to determine what records had changed in Dataverse.
