A developer created a Lightning web component for the Account record page that displays the five most recently contacted Contacts for an Account. The Apex method, getRecentContacts, returns a list of Contacts and will be wired to a property in the component.
Java
01:
02: public class ContactFetcher {
03:
04: static List<Contact> getRecentContacts(Id accountId) {
05: List<Contact> contacts = getFiveMostRecent(accountId);
06: return contacts;
07: }
08: private static List<Contact> getFiveMostRecent(Id accountId) {
10: //...implementation...
11: }
12: }
Which two lines must change in the above cod39e to make the Apex method able to be wired?

• A. Add public to line 04.
• B. Remove private from line 09.
• C. Add @AuraEnabled(cacheable=true) to line 08.
• D. Add @AuraEnabled(cacheable=true) to line 03.

Given a list of Opportunity records named opportunityList, which code snippet is best for querying all Contacts of the Opportunity's Account?

• A. 20
  Java
  List <Contact> contactList = new List <Contact>();
  for ( Contact c : [SELECT Id FROM Contact WHERE AccountId IN :opportunityList.AccountId ]){ contactList.add(c);
  }
• B. Java
  List <Contact> contactList = new List <Contact>();
  Set <Id> accountIds = new Set <Id>();
  for(Opportunity o : opportunityList){
  accountIds.add(o.AccountId);
  }
  for(Account a : [SELECT Id, (SELECT Id FROM Contacts) FROM Account WHERE Id IN :
  accountIds]){
  contactList.addAll(a.Contacts);
  }

A company has an Apex process that makes multiple extensive database operations and web service callouts.
The database processes and web services can take a long time to run and must be run sequentially. How should the developer write this Apex code without running into governor limits and system limitations?123

• A. Use Limits class to stop entire pr7ocess once governor limits are reached.8
• B. Use Apex Scheduler to schedul4e each process.56
• C. Use multip9le @future methods for each process and callout.
• D. Use Queueable Apex to chain the jobs to run sequentially.

The Account object has a field, Audit_Code__c, that is used to specify what type of auditing the Account needs and a Lookup to User, Auditor__c, that is the assigned auditor. When an Account is initially created, the user specifies the Audit_Code__c. Each User in the org has a unique text field, Audit_Code__c, that is used to automatically assign the correct user to the Account's Auditor__c field.
Trigger:
Java
trigger AccountTrigger on Account (before insert) {
AuditAssigner.setAuditor(Trigger.new);
}
Apex Class:
Java
public class AuditAssigner {
public static void setAuditor(List<Account> accounts) {
for (User u : [SELECT Id, Audit_Code__c FROM User]) {
for (Account a : accounts) {
if (u.Audit_Code__c == a.Audit_Code__c) {
a.Auditor__c = u.Id;
}
}
}
}
}
What should be changed to most optimize the code's efficiency?

• A. Build a Map<Id, List<String>> of Account Id to audit codes.
• B. Add a WHERE clause to the SOQL query to filter on audit codes.
• C. Build a Map<String, List<Account>> of audit code to accounts.
• D. Add an initial SOQL query to get all distinct audit codes.
