The test method tests an Apex trigger that the developer knows will make a lot of queries when a lot of Accounts are simultaneously updated. The test method fails at Line 20 because of "too many SOQL queries." What is the correct way to fix this?
Java
Line 12: //Set accounts to be customers
Line 13: for(Account a : DataFactory.accounts)
Line 14: {
Line 15: a.Is_Customer__c = true;
Line 16: }
Line 17:
Line 18: update DataFactory.accounts;
Line 19:
Line 20: List<Account> acctsAfter = [SELECT Number_Of_Transfers__c FROM Account WHERE Id IN :
DataFactory.accounts];

• A. Use Limits.getLimitQueries() to find the total number of queries that can be issued.
• B. Add Test.startTest() before and add Test.stopTest() after Line 18 of the code.
• C. Change the DataFactory class to create fewer Accounts so that the number of queries in the trigger is reduced.
• D. Add Test.startTest() before and add Test.stopTest() after both Line 7 and Line 20 of the code.

Business rules require a Contact to always be created when a new Account is created. What can be used when developing a custom screen to ensure an Account is not created if the creation of the Contact fails?

• A. Use the Database.Insert method with allOrNone set to false.
• B. Use setSavePoint() and rollback() with a try-catch block.
• C. Use a Database Savepoint method with a try-catch block.
• D. Use the Database.Delete method if the Contact insertion fails.

In an organization that has multi-currency enabled, a developer is tasked with building a Lighting component that displays the top ten Opportunities most recently accessed by the logged in user. The developer must ensure the Amount and LastModifiedDate field values are displayed according to the user's locale. What is the most effective approach to ensure values displayed respect the user's locale settings?1819

• A. Use REGEX expressions to format the values retrieved via SOQL.2425
• B. Use the FORMAT ( ) function in the SOQL query.2021
• C. Use a wrapper class to format the values retrieved via SOQL.2223
• D. Use the FOR VIEW clause in the SOQL query.2627

Refer to the code below:
Lightning Web Component JS file
JavaScript
import {LightningElement} from 'lwc';
import serverEcho from '@salesforce/apex/SimpleServerSideController.serverEcho'; export default class Helloworld extends LightningElement { firstName = 'world'; handleClick() { serverEcho({ firstName: this.firstName
})
.then((result) => {
alert('From server: ' + result);
})
.catch((error) => {
console.error(error);
});
}
}
Apex Controller
Java
public with sharing class SimpleServerSideController {
@AuraEnabled
public static String serverEcho(sObject firstName) {
String firstNameStr = (String)firstName.get('firstName');
return ('Hello from the server, ' + firstNameStr);
}
}
Given the code above, which two changes need to be made in the Apex Controller for the code to work?

• A. Remove line 06 from the Apex Controller and instead use firstName in the return on line 07.
• B. Change the method signature to be global static, not public static.
• C. Change the argument in the Apex Controller line 05 from sObject to String.
• D. Annotate the entire class as @AuraEnabled instead of just the single method.
