As part of a new integration, a developer is asked to implement a new custom search functionality that is capable of performing unrestricted queries and can account for all values within a custom picklist field, Type__c, on the Opportunity object. The search feature must also account for NULL values.
The organization-wide default for the Opportunity object is set to Public Read-Only, and a new custom index has been created for the Type__c field. There are more than 5 million Opportunity records within the environment, and a considerable amount of the existing records have NULL values for the picklist.
Which technique should the developer implement to maximize performance when querying NULL values?

A. Use a SOSL query to return ALL opportunities that have a value of NULL in any field.

B. Use the OR operator to combine WHERE clauses to strictly search for each value within the picklist, including Type__c = NULL.

C. Perform two SOQL queries; one to query Opportunities where Type__c != NULL, and another to query where Type__c = NULL, then join the result set using Apex.

D. Create a formula field that substitutes NULL values for a string of text, create an index for the formula field, then use the formula within the WHERE clause.

A developer must perform a complex SOQL query that joins two objects in a Lightning component.
How can the Lightning component execute the query?

A. Invoke an Apex class with the method annotated as @AuraEnabled to perform the query

B. Use the Salesforce Streaming API to perform the SOQL query

C. Create a Process Builder to execute the query and invoke from the Lightning component

D. Write the query in a custom Lightning web component wrapper and invoke from the Lightning component

C. Ensure the Apex Classes are on the same API version.

D. Ensure Process Builder processes are inactive.

As part of a new quality assurance effort, the company created an Event_Reviewer_ _c user lookup field on the object. Management wants the event reviewer to automatically gain Read/Write access to every record they are assigned to.
What is the best approach to ensure the assigned reviewer obtains Read/Write access to the record?

As part of a custom interface, a developer team creates various new Lightning web components. Each of the components handles errors using toast messages. When the development is complete, all the components are added to the same Lightning page.

C. SELECT Name, (SELECT LastName FROM Contacts) FROM Account

D. SELECT Id, Name, Account.Name FROM Contact WHERE Account.Industry = ‘Media’

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

A developer writes the following Apex trigger so that when a Case is closed, a single Survey record is created for that Case. The issue is that multiple Survey_c records are being created per Case. trigger CaseTrigger on Case (after insert, after update){ List createSurveys = new List<Survey_c>(); for (Case c : trigger.new){ if (c.IsClosed && (trigger.isInsert II trigger.isUpdate && trigger.oldMap.get(c.Id).IsClosed == false)){ createSurveys.add(new Survey_c(Case_c = c.Id)); } } insert createSurveys; }

@isTest
static void testIncrement() {
Account acct = new Account(Name = 'Test');
acct.Number_Of_Times_Viewed__c = 0;
insert acct;
AuditUtil.incrementViewed(acct.Id);
Account acctAfter = [SELECT Number_Of_Times_Viewed__c FROM Account WHERE Id = :acct.Id][0]
System.assertEquals(1, acctAfter.Number_Of_Times_Viewed__c);
}
The test method above calls an @future method that increments the Number_of_Times_Viewed__c value. The assertion is failing because the
Number_of_Times_Viewed__c equals 0.
What is the optimal way to fix this?

A. Change the initialization to acct.Number_Of_Times_Viewed__c = 1.

B. Add Test.startTest() before and Test.stopTest() after AuditUtil.incrementViewed.

C. Add Test.startTest() before and Test.stopTest() after insert acct.

D. Change the assertion to System.assertEquals(0, acctAfter.Number_Of_Times_Viewed__c).

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.
 
Which two changes should the developer make so the Apex method functions correctly? (Choose two.)

A. Add @AuraEnabled to line 09.

B. Add @AuraEnabled to line 03.

C. Add @AuraEnabled to lines 11 and 12.

C. Adds AJAX support to another component (e.g. onClick, onMouseUp, onFocus, etc.)

D. Can be associated with an AJAX request (actionFunction/actionSupport/actionPoller) and shows content conditionally depending on the status of the request (in progress/complete). Use the “id” field to specify name; use “status” field on related components to connect them

E. Signifies which components should be processed by the server when an AJAX request is generated
