When the sales team views an individual customer record, they need to see recent interactions for the customer. These interactions can be sales, orders, phone calls, or Cases. The date range for recent interactions will be different for every customer record type.

How can this be accomplished?

A Use a Lightning component to query and display interactions based on record type that is passed in using a design:attribute from the Lightning page.
B Use a dynamic form on the customer record page to display recent interactions.
C Use batch Apex to query for the most recent interactions when the customer view screen is loaded.
D Use Lightning Flow to read the customer's record type, and then do a dynamic query for recent interactions and display on the View page.

Which of the following object types can be used with a Web Service?

A Maps
B Sets
C Pattern objects
D Matcher objects
E Lists
F Exception objects

A company accepts orders for customers in their enterprise resource planning (ERP) system that must be integrated into Salesforce as Order__c records with a lookup field to Account. The Account object has an external ID field, ERP_Customer_ID__c.

What should the integration use to create new Order__c records that will automatically be related to the correct Account?

A Insert on the Order__c object followed by an update on the Order__c object.
B Merge on the Order__c object and specify the ERP_Customer_ID__c for the Account relationship.
C Upsert on the Order__c object and specify the ERP_Customer_ID__c for the Account relationship.
D Upsert on the Account and specify the ERP_Customer_ID__c for the relationship.

A developer creates a Lightning web component to allow a Contact to be quickly entered. However, error messages are not displayed.

Question Image

Which component should the developer add to the form to display error messages?

A lightning-messages
B aura:messages
C lightning-error
D apex:messages

A developer sees test failures in the sandbox but not in production. No code or metadata changes have been actively made to either environment since the sandbox was created.

Which consideration should be checked to resolve the issue?

A Ensure the sandbox is on the same release as production.
B Ensure Workflow Rules are inactive.
C Ensure the Apex Classes are on the same API version.
D Ensure Process Builder processes are inactive.

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

What is the optimal way to automate this?

A Apex invocable method
B Remote action
C Flow Builder
D Apex trigger

Users complain that a page is very slow to respond. Upon investigation, the query below is found to perform slowly.

Question Image

Which two actions can a developer take to improve performance? (Choose two.)

A Make the CustomField_c field an External ID.
B Make the field CustomField_c required because Salesforce field indexes do not include nulls.
C Add a LIMIT clause to the query to reduce the number of records returned.
D Contact Salesforce customer support to create a custom index to include null values.

Which interface needs to be implemented by a Lightning Component so that it may be displayed in modal dialog by clicking a button on a Lightning Record page?

A force:lightningQuickAction
B lightning:quickAction
C lightning:editAction
D force:lightningEditAction

A company has a custom object, Sales Demo Request, that has a lookup to an Opportunity. It is required that a Sales Demo Request record be created when an
Opportunity's Probability is greater than 50%.

A Bulk API
B SOAP API
C Apex REST Web Service
D Composite REST API

A company wants to implement a new call center process for handling customer service calls. It requires service reps to ask for the caller's account number before proceeding with the rest of their call script.
Following best practices, what should a developer use to meet this requirement?

A Apex Trigger
B Process Builder
C Flow Builder
D Approvals

A large company uses Salesforce across several departments. Each department has its own Salesforce Administrator. It was agreed that each Administrator would have their own sandbox in which to test changes.
Recently, users notice that fields that were recently added for one department suddenly disappear without warning. Also, Workflows that once sent emails and created tasks no longer do so.
Which two statements are true regarding these issues and resolution? (Choose two.)

A The administrators are deploying their own Change Sets, thus deleting each other's fields from the objects in production.
B A sandbox should be created to use as a unified testing environment instead of deploying Change Sets directly to production.
C Page Layouts should never be deployed via Change Sets, as this causes Workflows and Field-level Security to be reset and fields to disappear.
D The administrators are deploying their own Change Sets over each other, thus replacing entire Page Layouts and Workflows in Production.

What is a benefit of JavaScript remoting over Visualforce Remote Objects?

A Allows for specified re-render targets
B Does not require any Apex code
C Does not require any JavaScript code
D Supports complex server-side application logic

Recently a Salesforce org's integration failed because it exceeded the number of allowed API calls in a 24-hour period. The integration handles a near real-time, complex insertion of data into Salesforce.
The flow of data is as follows:
✑ The integration looks up Contact records with a given email address and, if found, the integration adds a Task to the first matching Contact it finds.
✑ If a match is not found, the integration looks up Lead records with a given email address and, if found, the integration adds a Task to the first matching Lead it finds.
✑ If a match is not found, the integration will create a Lead and a Task for that newly created Lead.
What is one way in which the integration can stay near real-time, but not exceed the number of allowed API calls in a 24-hour period?

A Use the REST API as well as the SOAP API to effectively double the API calls allowed in a 24-hour period.
B Create an Inbound Message that, using Flow, can do all of the logic the integration code was doing.
C Write a custom Apex web service that, given an email address, does all of the logic the integration code was doing.
D Create several Apex InboundEmailHandlers to accept calls from the third-party system, thus bypassing the API limits.

A developer created a new trigger that inserts a Task when a new Lead is created. After deploying to production, an outside integration is periodically reporting errors.
Which change should the developer make to ensure the integration is not affected with minimal impact to business logic?

A Remove the Apex Class from the Integration User's Profile.
B Use the Database method with allOrNone set to False.
C Use a Try/Catch block after the insert statement.
D Deactivate the Trigger before the Integration runs.

A developer is trying to access org data from within a test class.
Which sObject type requires the test class to have the (seeAllData=true) annotation?

A Report
B User
C Profile
D RecordType

A developer is asked to update data in an org based on new business rules. The new rules state that Accounts with the type set to 'Customer' should have a status of 'Active', and Accounts with the type set to 'Prospect' should have a status of 'Pending'. No other changes to data should be made.
Which code block will accurately meet the business requirements?

A Map<String, String> statusMap = new Map<String, String>{'Customer'=>'Active', 'Prospect'=>'Pending'} List<Account> accountUpdates = new List<Account>(); for ( Account a : [SELECT Id, Type FROM Account]){ if ( statusMap.containsKey(a.Type) ) { a.Status = a.Type == 'Customer' ? 'Active' : 'Pending'; } accountUpdates.add(a); } update accountUpdates;
B Map<String, String> statusMap = new Map<String, String>{'Customer'=>'Active', 'Prospect'=>'Pending'} List<Account> accountUpdates = new List<Account>(); for ( Account a : [SELECT Id, Type FROM Account WHERE Status IN :statusMap.keySet()]){ a.Status = statusMap.get(a.Type); accountUpdates.add(a); } update accountUpdates;
C List<Account> accountUpdates = new List<Account>(); for ( Account a : [SELECT Id, Type FROM Account]){ if ( String.isNotBlank(a.Type) && a.Type == 'Customer' ){ a.Status = 'Active'; } if ( String.isNotBlank(a.Type) && a.Type == 'Prospect' ){ a.Status = 'Pending'; } accountUpdates.add(a); } update accountUpdades;
D List<Account> accountUpdates = new List<Account>(); for ( Account a : [SELECT Id, Type FROM Account]){ a.Status = a.Type == 'Customer' ? 'Active' : 'Pending'; accountUpdates.add(a); } update accountUpdates;

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 a @testSetup method in the test class.
C Move the prerequisite reference data setup to a static method in the test class and call that from each test method.
D Move the prerequisite reference data setup to the constructor for the test class.

A developer is trying to decide between creating a Visualforce component or a Lightning component for a custom screen.
Which functionality consideration impacts the final decision?

A Does the screen need to be rendered as a PDF?
B Does the screen need to be accessible from the Lightning Experience UI?
C Will the screen make use of a JavaScript framework?
D Will the screen be accessed via a mobile app?

A company recently deployed a Visualforce page with a custom controller that has a data grid of information about Opportunities in the org. Users report that they receive a Maximum view state size limit error message under certain conditions.
According to Visualforce best practice, which three actions should the developer take to reduce the view state? (Choose three.)

A Use the transient keyword in the Apex controller for variables that do not maintain state
B Use the final keyword in the controller for variables that will not change
C Use the private keyword in the controller for variables
D Refine any SOQL queries to return only data relevant to the page
E Use filters and pagination to reduce the amount of data

Choose the correct definition for <apex:messages>.

A Standard Salesforce formatting, throws a specific message on a page
B Standard Salesforce formatting, shows all errors that occur on page. Can add more messages through the "ApexPages.addMessage" function
C A single message, without formatting, that can be associated with a specific component on the page
