A company has reference data stored in multiple custom metadata records that represent default information and delete behavior for
certain regions.

When a contact is inserted, the default information should be set on the contact from the custom metadata records based on the contact's address information. Additionally. if a user attempts to delete a contact that belongs to a flagged region, the user must get an error message.

Depending on company personnel resources, what are two ways to
automate this?

Apex trigger

Flow builder

Remote Action

Apex Invocable method

AW Computing (AWC) handles orders in Salesforce and stores its product inventory in a field, Inventory__c, on a custom object, Product__c. When an order for a Product__c is placed, the Inventory__c field is reduced by the quantity of the order using an Apex trigger.

public void reduceInventory(Id prodId, Integer qty) {	Integer newInventoryAmt = getNewInventoryAmt(prodId, qty);	Product__c p = new Product__c(Id=prodId, Inventory__c= newInventoryAmt);	update p;	//code goes here}

AWC wants the real-time inventory reduction for a product to be sent to many of its external systems, including some future systems the company is currently planning.

What should a developer add to the code at the placeholder to meet these requirements?

InventoryReductionEvent__c ev = new InventoryReductionEvent__c(ProductId__c=prodId, Reduction__c = qty); insert ev;

InventoryReductionEvent__e ev = new InventoryReductionEvent__e(ProductId__c=prodId, Reduction__c = qty); insert ev;

InventoryReductionEvent__c ev = new InventoryReductionEvent__c(ProductId__c=prodId, Reduction__c = qty); EventBus.publish(ev);

InventoryReductionEvent__e ev = new InventoryReductionEvent__e(ProductId__c=prodId, Reduction__c = qty); EventBus.publish(ev);

A developer is working with existing functionality that tracks how many times a stage has changed for an Opportunity. When the Opportunity's stage is changed, a workflow rule is fired to increase the value of a field by one. The developer wrote an after trigger to create a child record when the field changes from 4 to 5.
A user changes the stage of an Opportunity and manually sets the count field to 4. The count field updates to 5, but the child record is not created.
What is the reason this is happening?

After triggers are not fired after field updates.

Trigger.old does not contain the updated value of the count field.

Trigger.new does not change after a field update.

After triggers fire before workflow rules.

An org has a requirement that an Account must always have one and only one Contact listed as Primary. So selecting one Contact will de-select any others. The client wants a checkbox on the Contact called 'Is Primary' to control this feature. The client also wants to ensure that the last name of every Contact is stored entirely in uppercase characters.
What is the optimal way to implement these requirements?

Write an after update trigger on Contact for the Is Primary logic and a separate before update trigger on Contact for the last name logic.

Write an after update trigger on Account for the Is Primary logic and a before update trigger on Contact for the last name logic.

Write a Validation Rule on the Contact for the Is Primary logic and a before update trigger on Contact for the last name logic.

Write a single trigger on Contact for both after update and before update and callout to helper classes to handle each set of logic

Refer to the test method below:

@isTeststatic void testAccountUpdate() {    Account acct = new Account(Name = 'Test');    acct.Integration Updated_c = false;    insert acct;}CalloutUtil.sendAccountUpdate(acct.Id);Account acctAfter = [SELECT Id, Integration_Updated__c FROM Account WHERE Id =: acct.Id][0];System.assert(true, acctAfter.Integration_Updated__c);

The test method calls a web service that updates an external system with Account information and sets the Account's Integration Updated_c checkbox to True when it completes.
The test fails to execute and exits with an error: "Methods defined as TestMethod do not support Web service callouts."
What is the optimal way to fix this?

Add if (!Test.isRunningTest ()) around calloutUtil.sendAccountUpdate.

Add Test.startTest() and Test.setMock before and Test.stopTest() after CalloutUtil.sendAccount Update.

Add Test.startTest() before and Test.stopTest() after calloutUtil.sendAccount Update.

Add Test.startTest() before and Test.setMock and Test.stopTest() after CalloutUtil.sendAccountUpdate.

Consider the controller code below that is called from an Aura component and returns data wrapped in a class.

public class myserversideController {     @AuraEnabled     public static MyDataWrapper getsomeData( String theType) {         Some_Object_c someobj = [              SELECT ID, Name             FROM Some_Object_c             WHERE Type_c = : theType             LIMIT 1        ];            Another_Object_o anotherobj = [             SELECT ID, Option_c             FROM Another_Object_c             WHERE Some_Object_c = :someObj.Name             LIMIT 1         ];         MyDataWrapper theData = new MyDataWrapper();         theData.Name = someObj.Name;         theData.Option = anotherobj.Option_c;         return theData;     }    public class MyDataWrapper {         public string Name { get; set; }         public string option { get; set; }         public MyDatawrapper () { }    }}

The developer verified that the queries return a single record each and there is error handling in the Aura component, but the component is not getting anything back when calling the controller getsomeData().
What is wrong?

The member's Name and option of the class MyDataWrapper should be annotated with @AuraEnabled also.

The member's Name and option should not have getter and setter.

Instances of Apex classes, such as MyDataWrapper, cannot be returned to a Lightning component.

The member's Name and option should not be declared public

Enclose the DATA table within the tag.

Implement the reRender attribute on the tag.

Implement the tag with immediate = true.

Ensure the action method search returns null.

25 / 52

An Apex class does not achieve expected code coverage. The testsetup method explicitly calls a method in the Apex class.
How can the developer generate the code coverage?

Call the Apex class method from a testMethod instead of the testsetup method.

Add @testVisible to the method in the class the developer is testing.

Verify the user has permissions passing a user into System.runAs ().

Use system.assert() in testsetup to verify the values are being returned.

26 / 52

Fire a custom component event.

Fire an application event.

27 / 52

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?

Use a wrapper class to format the values retrieved via SOQL.

Use the FOR VIEW clause in the SOQL query.

Use the FORMAT() function in the SOQL query.

Use REGEX expressions to format the values retrieved via SOQL.

28 / 52

An Apex trigger creates a Contract record every time an Opportunity record is marked as Closed and Won. This trigger is working great, except (due to a recent acquisition) historical Opportunity records need to be loaded into the Salesforce instance.
When a test batch of records are loaded, the Apex trigger creates Contract records. A developer is tasked with preventing Contract records from being created when mass loading the Opportunities, but the daily users still need to have the Contract records created.
What is the most extendable way to update the Apex trigger to accomplish this?

Use a list custom setting to disable the trigger for the user who loads the data.

Add the Profile ID of the user who loads the data to the trigger, so the trigger will not fire for this user.

Use a hierarchy custom setting to skip executing the logic inside the trigger for the user who loads the data.

Add a validation rule to the Contract to prevent Contract creation by the user who loads the data.

29 / 52

A developer is asked to build a solution that will automatically send an email to the customer when an Opportunity stage changes.

The criteria to send the email should be evaluated after certain conditions are met. What is the optimal way to accomplish this?

Use an Email Alert with Flow Builder.

Use a Workflow Email Alert.

Use SingleEmailMessage() with an Apex trigger

Use MassEmailMessage () with an Apex trigger.

30 / 52

Which technique can run custom logic when a Lightning web component is loaded?

Use the connectedCallback() method

Consider the following code snippet:

public static List<Account> getAccounts (Date thisDate, Id goldenRT) {     List<Account> accountList = [Select Id, Name, Industry FROM Account WHERE CreatedDate = thisDate     OR RecordTypeId = :goldenRT];     return accountList; }

The Apex method is executed in an environment with a large data volume count for Accounts, and the query is performing poorly. Which technique should the developer implement to ensure the query performs optimally, while preserving the entire result

Create a formula field to combine the CreatedDate and RecordType value, then filter based on the formula.

Annotate the method with the @Future annotation.

Break down the query into two individual queries and join the two result sets.

Use the Database.queryLocator method to retrieve the accounts.

32 / 52

Universal Containers decided to use Salesforce to manage a new hire interview process. A custom object called Candidate was created with organization-wide defaults set to Private. A lookup on the Candidate object sets an employee as an Interviewer.
What should be used to automatically give Read access to the record when the lookup field is set to the Interviewer user?

The record can be shared using an Apex class.

The record cannot be shared with the current setup.

The record can be shared using a permission set.

The record can be shared using a sharing rule. Mark this item for later review.

33 / 52

A developer is debugging an Apex-based order creation process that has a requirement to have three savepoints, SP1, SP2, and SP3 (created in order), before the final execution of the process.
During the final execution process, the developer has a routine to roll back to SP1 for a given condition. Once the condition is fixed, the code then calls a roll back to SP3 to continue with final execution. However, when the roll back to SP3 is called, a
runtime error occurs..
Why does the developer receive a runtime error?

The developer used too many savepoints in one trigger session

SP3 became invalid when SP1 was rolled back.

The developer has too many DML statements between the savepoints.

The developer should have called SP2 before calling SP3.

34 / 52

An org records customer order information in a custom object, order_c, that has fields for the shipping address. A developer is tasked with adding code to calculate shipping charges on an order, based on a flat percentage rate associated with the region of the shipping address.
What should the developer use to store the rates by region, so that when the changes are deployed to production no additional steps are needed for the calculation to work?

Custom hierarchy setting

Custom metadata type

Custom object

Custom list setting

Consider the Apex class below that defines a RemoteAction used on a Visualforce search page.

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);

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

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

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

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 AccountTrigger on Account(before insert) {    AuditAssigner.setAuditor(Trigger.new);}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;                }            }        }    }

A developer created an Opportunity trigger that updates the account rating when an associated opportunity is considered high-value. The current criteria for an opportunity to be considered high value is an amount greater than or equal to $1,000,000. However, this criteria value can change over time. There is a new requirement to also display high-value opportunities in a Lightning web component.
Which two actions should the developer take to meet these business requirements, and also prevent the business logic that obtains the high-value opportunities from being repeated in more than one place?
Choose 2 answers

Use custom metadata to hold the high value amount.

Create a helper class that fetches the high value opportunities.

Leave the business logic code inside the trigger for efficiency.

Call the trigger from the Lightning web component.

Just prior to a new deployment the Salesforce administrator, who configured a new order fulfillment process feature in a
developer sandbox, suddenly left the company. As part of the UAT cycle, the users had fully tested all of the changes in the sandbox and signed off on them; making the Order fulfillment feature ready for its go-live in the production environment. Unfortunately although a Change Set was started, it was not completed by the former administrator. A developer is brought in to finish the deployment.
What should the developer do to identify the configuration changes that need to be moved into production?

Set up Continuous Integration and a Git repository to automatically merge all changes from the sandbox metadata with the production metadata.

Use the Metadata API and a supported development IDE to push all of the configuration from the sandbox into production to ensure no changes are lost.

In Salesforce setup, look at the last modified date for every object to determine which should be added to the Change Set.

Leverage the Setup Audit Trail to review the changes made by the departed Administrator and identify which changes should be added to the Change Set.

A developer is experiencing issues with a Lightning web component. The component must surface information about Opportunities owned by the currently logged-in user. When the component is rendered, the following message is displayed: "Error retrieving data".
Which modification should be implemented to the Apex class to overcome the issue?

Edit the code to use the without sharing keyword in the Apex class.

Use the continuation=true attribute in the Apex method.

Use the cacheable=true attribute in the Apex method.

Ensure the OWD for the Opportunity object is Public.

A developer is debugging an Apex-based order creation process that has a requirement to have three savepoints, SP1, SP2, and SP3 (created in order), before the final execution of the process.

During the final execution process, the developer has a routine to roll back to SP1 for a given condition.

Once the condition is fixed, the code then calls a rollback to SP3 to continue with the final execution. However, when the rollback to SP3 is called, a runtime error occurs.

Why does the developer receive a runtime error?

SP3 became invalid when SP1 was rolled back

The developer used too many savepoints in one trigger session

The developer has too many DML statements between the savepoint

The developer should have called SP2 before calling SP3

public class ERPCatalog {	private final ERP CATALOG URL = http//sampleCatalog.com/cat'; 	public String getERPCatalogContents()  {		Http h = new Http(); 		HttpRequest req = new HttpRequest(); req.setEndpoint (ERP CATALOG URL); 		req.setMethod('GET'); 		HttpResponse res = h.send(req); 		return res.ge_Body(); 	}}

When the code is executed, the callout is unsuccessful, and the test fails to execute and exits with an error: "Methods defined as TestMethod do not support Web Service callouts".
What is the optimal way to fix this?

Add Test.startTest() before and cost.set took and Test.stopTest() after Callout.util.SendAccountUpdate.

Add if (!Test.isRunningTest ()) around CalloutUtil.sendaccountUpdate.

Add Test.startTest() and test.setMock before and Test..stopTest() after CalloutUtil.sendAccountUpdate.

Add Test.startTest() before and Test.stopTest() after calloutUtil.sendAccountUpdate.

A developer has a working business logic code, but sees the following error in the test class:

You have uncommitted work pending. Please commit or rollback before calling out.

What is a possible solution?

Call support for help with the target endpoint, as it Is likely an external code error.

Rewrite the business logic and test classes with @TestVisible set on the callout.

Set seeAllData to true at the top of the test class, since the code does not fall in practice.

Use tast. IsRunningTest() before making the callout to bypass it in test execution

When a test batch of records are loaded, the Apex trigger: creates Contract records. A developer is tasked with preventing Contract records from being created when mass loading the Opportunities, but the daily users still need to have the Contract records created.

What is the most extendable way to update the Apex trigger to accomplish this?

Use a list custom setting to disable the trigger for the user who loads the data

Add a validation rule to the Contract to prevent Contract creation by the user who loads the data

Use a hierarchy custom setting to skip executing the logic inside the trigger for the user who loads the data.

Add the Profile ID of the user who loads the data to the trigger, so the trigger will not fire for this user

Just prior to a new deployment the Salesforce administrator, who configured a new order fulfillment process feature in a developer sandbox, suddenly left the company.

As part of the UAT cycle, the users had fully tested all of the changes in the sandbox and signed off on them; making the Order fulfillment feature ready for Its go-live in the production

Unfortunately although a Change Set was started, it was not completed by the former administrator. A developer is brought in to finish the deployment.

What should the developer do to identify the configuration

changes that need to be moved into production?

Refer to the following code snippets:

MyOpportunities.js

import {LightningElement, api, wire } from 'lwc';import getOpportunities from salesforce/apex/OpportunityController.findMyopportunities export default class Myopportunities extends LightningElement {	@api userId; 	@wire (getOpportunities, {oppOwner: '$userId'})	opportunities;}OpportunityController.clspublic with sharing class OpportunityController { @AuraEnabled public static Opportunity getOpportunities(Id oppOwner) {}

A developer is experiencing issues with a Lightning web Component. The component must surface information about Opportunities owned by the currently logged-in user.

When the component is rendered, the following message is displayed: "Error retrieving data".

Which modification should be implemented to the Apex class to overcome the issue?

Use the continuation-true attribute in the Apex method.

Ensure the OWD for the Opportunity object is Public.

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?

Use the FORMAT() function in the SOQL query.

Use REGEX expressions to format the values retrieved via SOOL.

Use a wrapper class to format the values retrieved via SOQL

Use the FOR VIEW clause in the SOQL query

Consider the following code snippet:

public static List<Account> getAccounts (Date thisDate, Id goldenRT) {	List<account accountList = [Select Id, Name, Industry 		FROM Account WHERE CreatedDate = thisDate OR RecordIypeId :goldenRI] 	return accountList; }

The Apex method is executed in an environment with a large data volume count for Accounts, and the query is performing poorly.

Which technique should the developer implement to ensure the query performs optimally while preserving the entire result set?

Create a formula field to combine the CreatedDate and RecordType value, then filter based on the formula.

Use the Database.queryLocator methd to retrieve the accounts

Break down the query into two individual queries and join the two result sets

Annotate the method with @Future annotation

A company has code to update a Request and Request Lines and make a callout to their external ERP system's REST endpoint with the updated records.

public void updateAndMakeCallout (Map<Id, Request__c> reqs, Map<Id, Request_Line__c> reqlines) { 	Savepoint sp = database.setSavepoint(); 	try { 		insert reqs.values(); 		insert reqlines.values(); 		HttpResponse response = CalloutUtil.makeRestCallout (reqs.keyset(), 		reqLines.keySet()); 	catch (Exception e) { 		Database.rollback(sp): 		System.debug(e);	}}

The callout. util.makeRestcallout fails with a "You have uncommitted work pending. Please commit or roll back before calling out error.

What should be done to address the problem?

Remove the Database.setSavepoint and Database.rollback.

Change the calloutULil.makeRestCallout to an @InvocableMethod method.

Move the calloutUtil.makeRestCallout method call below the catch block.

Change the calloutUtil.makeRestCallout to an @future method.

A developer has a test class that creates test data before making a mock callout but now receives a 'You have uncommitted work

pending. Please commit or rollback before calling out' error.

Which step should be taken to resolve the error?

Ensure both the insertion and mock callout occur after the Test.stopText().

Ensure the records are inserted before the Test.startTest() statement and the mock callout occurs within a method annotated with @testSetup.

Ensure the records are inserted before the Test.startTest() statement and the mock callout occurs after the Test.startTest()

Ensure both the insertion and mock callout occur after the Test.startTest().
