質問 # 71
Refer to the exhibit

Users of this Visualforce page complain that the page does a full refresh every time the Search button Is pressed.
What should the developer do to ensure that a partial refresh Is made so that only the section identified with opportunity List is re-drawn on the screen?

• A. Implement the render attribute on the <apex:ccxmandButton> tag.
• B. Ensure the action method search returns null.
• C. Enclose the DATA table within the <apex:actionRegion> tag.
• D. Implement the <apex:actionfunction> tag with immediate = true.

正解：A

解説：
The developer should implement the render attribute on the apex:commandButton tag to ensure that a partial refresh is made so that only the section identified with opportunity List is re-drawn on the screen. The render attribute specifies the ID of one or more components that are redrawn when the result of an AJAX update request returns to the client. The developer can use the render attribute to limit the scope of the refresh to the apex:pageBlock component that contains the data table, and avoid refreshing the entire page. Enclosing the data table within the apex:actionRegion tag will not help, as the apex:actionRegion tag defines a section of a page that demarcates a form within a form, and allows the developer to limit the processing of form elements to the contents of the region. However, it does not affect the refresh of the page or the components. Ensuring the action method search returns null will not help, as it will only prevent the page from reloading, but it will not refresh the data table with the new search results. Implementing the apex:actionFunction tag with immediate = true will not help, as the apex:actionFunction tag defines a JavaScript function that can invoke a controller action method, and the immediate attribute specifies whether the action method is executed immediately, without processing any validation rules. However, it does not affect the refresh of the page or the components. Reference: [apex:commandButton], [apex:actionRegion], [apex:actionFunction], [Visualforce Developer Guide]

• B. Use to create a JavaScript wrapper for the controller method.
• C. Use the $Controller global variable to access the controller method via JavaScript.
• D. Use to enable JavaScript support for the controller method.

質問 # 75
A business requires that every parent record must have a child record. A developer writes an Apex method with two DML statements to insert a parent record and a child record.
A validation rule blocks child records from being created. The method uses a try/catch block to handle the DML exception.
What should the developer do to ensure the parent always has a child record?

• A. Use Catabase.inserc() and set the all = parameter to true,
• B. Set a database savepoint to rollback if there are errors.
• C. Delete the parent record in the catch statement when an error occurs on the child record DML operation.
• D. Use addExror() on the parent record if an error occurs on the child record.

正解：C

解説：
To ensure the parent always has a child record, the developer should use Database.insert and set the allOrNone parameter to false. The Database.insert method is a variant of the insert DML statement that allows the developer to specify whether to roll back the entire transaction or allow partial success when an error occurs. The allOrNone parameter is a Boolean value that determines this behavior. If the allOrNone parameter is set to true, the entire transaction is rolled back if any record causes an error, which is the same as the insert statement. If the allOrNone parameter is set to false, the records that do not cause errors are inserted, and the ones that do cause errors are returned in a Database.SaveResult array. The developer can then handle the errors accordingly. In this scenario, the developer should use Database.insert and set the allOrNone parameter to false, so that the parent record can be inserted even if the child record fails the validation rule. The developer can then catch the DML exception and display an appropriate error message to the user. Deleting the parent record in the catch statement when an error occurs on the child record DML operation would not ensure the parent always has a child record, as it would remove the parent record as well. Setting a database savepoint to rollback if there are errors would not ensure the parent always has a child record, as it would undo the entire transaction if the child record fails the validation rule. Using addError on the parent record if an error occurs on the child record would not ensure the parent always has a child record, as it would prevent the parent record from being inserted as well.

質問 # 81
Which use case can be performed only by using asynchronous Apex?

• A. Updating a record after the completion of an insert
• B. Calling a web service from an Apex trigger
• C. Making a call to schedule a batch process to complete in the future
• D. Querying tens of thousands of records

正解：B

解説：
Making a callout from an Apex trigger is not allowed synchronously; hence, such callouts must be performed in an asynchronous context. The only way to perform this within the Salesforce platform is by using asynchronous Apex, such as @future methods or Queueable Apex.References: Apex Developer Guide - Asynchronous Apex

質問 # 83
A company notices that their unit tests in a test class with many methods to create many records for prerequisite reference data are slow.
What can a developer to do address the issue?

• A. Move the prerequisite reference data setup to a TestDataFactory and call that from each test method,
• B. Move the prerequisite reference data setup to the constructor for the test class.
• C. Turn off triggers, flows, and validations when running tests.
• D. Move the prerequisite reference data setup to a @testSetup method in the test class.

正解：D

解説：
To address the issue of slow unit tests in a test class with many methods that create many records for prerequisite reference data, a developer should move the prerequisite reference data setup to a @testSetup method in the test class. A @testSetup method is a special method that runs once before all test methods in a test class and creates common test data for all test methods. This can improve the performance of the test class by reducing the number of DML operations and avoiding code repetition. The test methods can access the test data created by the @testSetup method by using SOQL queries or the Test.loadData() method. Reference: [@testSetup Annotation], [Create Test Data for Apex Tests], [Test.loadData Method]
