Question 2

A developer created a Lightning web component that allows users to input a text value that is used to search for Accounts by calling an Apex method. The Apex method returns a list of AccountWrappers and is called imperatively from a JavaScript event handler.
Java
01: public class AccountSearcher {
02:
03: public static List<AccountWrapper> search(String term) {
04: List<AccountWrapper> wrappers = getMatchingAccountWrappers(term);
05: return wrappers;
06: }
07:
08:
09: public class AccountWrapper {
10: public Account account { get; set; }
11: public Decimal matchProbability { get; set; }
12: }
13: // ...other methods, including getMatchingAccountWrappers implementation...
14: }
Which two changes should the developer make so the Apex method functions correctly?

A. Add @AuraEnabled to lines 10 and 11.

B. Add @AuraEnabled to line 03.

C. Add @AuraEnabled to line 09.

D. Add @AuraEnabled to line 01.

Question 5

Universal Containers (UC) has enabled the translation workbench and has translated picklist values. UC has a custom multi-select picklist field, Products__c, on the Account object that allows sales reps to specify which of UC's products an Account already has. A developer is tasked with writing an Apex method that retrieves Account records, including the Products__c field. What should the developer do to ensure the value of Products__c is in the current user's language?40

A. Call the translate() method on each record in the SOQL result list.

B. Use toLabel(Products__c) in the fields list of the SOQL que41ry.

C. Use the locale clause in the SOQL query.

D. Set the locale on each record in the SOQL result list.

Question 6

Refer to the code snippet below:
Java
public static void updateCreditMemo(String customerId, Decimal newAmount){ List<Credit_Memo__c> toUpdate = new List<Credit_Memo__c>(); for(Credit_Memo__c creditMemo : [Select Id, Name, Amount__c FROM Credit_Memo__c WHERE Customer_Id__c = :customerId LIMIT 50]) { creditMemo.Amount__c = newAmount; toUpdate.add(creditMemo);
}
Database.update(toUpdate,false);
}
A custom object called Credit_Memo__c exists in a Salesforce environment. As part of a new feature development, the developer needs to ensure race conditions are prevented when a set of records are mod1ified within an Apex transaction. In the preceding Apex code, how can the developer alter the que2ry statement to use SOQL features to prevent race conditions within a tr3ansaction?4

A. [Select Id, Name, Amount__c FROM Credit_Memo__c WHERE Customer_Id__c = :customerId LIMIT 50 FOR REFERENCE]

B. [Select Id, Name, Amount__c FROM Credit_Memo__c WHERE Customer_Id__c = :customerId LIMIT 50 FOR UPDATE]

C. [Select Id, Name, Amount__c FROM Credit_Memo__c WHERE Customer_Id__c = :customerId USING SCOPE LIMIT 50]

D. [Select Id, Name, Amount__c FROM Credit_Memo__c WHERE Customer_Id__c = :customerId LIMIT 50 FOR VIEW]

Question 7

Consider the Apex class below that defines a RemoteAction used on a Visualforce search page.
Java
global with sharing class MyRemoter {
public String accountName { get; set; }
public static Account account { get; set; }
public MyRemoter() {}
@RemoteAction
global static Account getAccount(String accountName) {
account = [SELECT Id, Name, NumberOfEmployees FROM Account WHERE Name = :accountName]; return account;
}
}
Which code snippet will assert that the remote action returned the correct Account?

Account a = controller.getAccount('TestAccount');
System.assertEquals( 'TestAccount', a.Name );

B. Java
Account a = MyRemoter.getAccount('TestAccount');
System.assertEquals( 'TestAccount', a.Name );

C. Java
MyRemoter remote = new MyRemoter('TestAccount');
Account a = remote.getAccount();
System.assertEquals( 'TestAccount' , a.Name );

D. Java
MyRemoter remote = new MyRemoter();
Account a = remote.getAccount('TestAccount');
System.assertEquals( 'TestAccount', a.Name );
