73. Consider the controller code above that is called from a Lightning component and returns data wrapped in a class.

Consider the controller code above that is called from a Lightning component and returns data wrapped in a class.

The developer verified that the Queries return a single record each and there is error handing in the Lightning 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 too.

The member's Name and Option should not be declared public.

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.

74. 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.

What could be the cause of this issue?

A user is creating the record as Closed

A workflow rule is firing with a Create Task action

A workflow rule is firing with a Field Update action

A user is editing the record multiple times

75. Within the System.Limit class, what would you call to get the number of calls made in your transaction?

get [typeOfLimit] ―> (Ex. getDXLStaterr.ents () )

getLimit [typeOf Limit] ―> (Ex. getLirr.it DXLSt at err.ents () )

76. A developer created and tested a Visualforce page in their developer sandbox, but now receives reports that users are encountering ViewState errors when using it in Production.

Ensure queries do not exceed governor limits.

Ensure properties are marked as Transient.

Ensure properties are marked as private.

Ensure profiles have access to the Visualforce page.

77. The REST API___________.

Is based on REST principles and is optimized for loading or deleting large sets of data. You can use it to query, queryAII, insert, update, upsert, or delete many records asynchronously by submitting batches

Provides a powerful, convenient, and simple REST-based web services interface for interacting with Salesforce. Its advantages include ease of integration and development, and it's an excellent choice of technology for use with mobile applications and web projects

Is used to create, retrieve, update or delete records, such as accounts, leads, and custom objects, and allows you to maintain passwords, perform searches, and much more

Is used to retrieve, deploy, create, update, or delete customizations for your org. The most common use is to migrate changes from a sandbox or testing org to your production environment

80. A custom field Exec_Count_c of type Number is created on an Account object. An account record with value of "1" for a: Exec__Count_c is saved. A workflow field update is defined on the Exec_Count_c field, to increment its value every time an account record is created or updated.

The following trigger is defined on the account:

trigger ExecOrderTrigger on Account (before insert, before update, after insert, after update){ for (Account accountlnstance: Trigger.New){ if (Trigger . isBefore){ accountlnstance Exec_Count_c += 1; } System, debug (accountlnstance.Exec_Count_c); } }

81. 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?

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

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

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

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

82. An environment has two Apex Triggers: an after-update trigger on Account and an after-update trigger on Contact. The Account after-update trigger fires whenever an Account's address is updated, and it updates every associated Contact with that address. The Contact after-update trigger fires on every edit, and it updates every Campaign Member record related to the Contact with the Contact's state.

Consider the following: A mass update of 200 Account records' addresses, where each Account has 50 Contacts. Each Contact has 1 Campaign Member. This means there are 10,000 Contact records across the Accounts and 10,000 Campaign Member records across the contacts.

What will happen when the mass update occurs?

The mass update will fail, since the two triggers fire in the same context, thus exceeding the number of records processed by DML statements.

There will be no error, since each trigger fires within its own context and each trigger does not exceed the limit of the number of records processed by DML| statements.

There will be no error, since the limit on the number of records processed by DML statements is 50,000.

The mass update of Account address will succeed, but the Contact address updates will fail due to exceeding number of records processed by DML statements.

83. A company needs to automatically delete sensitive information after 7 years. This could

delete almost a million records every day.

How can this be achieved?

Schedule an ©future process to Query records older than 7 years, and then recursively invoke itself in 1,000 record batches to delete them.

Perform a SOSL statement to find records older than 7 years, and then delete the entire result set.

Use aggregate functions to query for records older than 7 years, and then delete the AggregateResult objects.

Schedule a batch Apex process to run every day that Queries and deletes records older than 7 years.

84. As part of a custom development, a developer creates a Lightning Component to show how a particular opportunity progresses over time.

The component must display the date stamp when any of the following fields change:

• Amount Probability, Stage, or Close Date

What is the most efficient way to Query such information?

[Select Amount, CloseDate, StageName, Probability FROM OpportunityHistory WHERE Opportunityld = :oppId];

[Select Newvalue, Oldvalue From OpportunityField_History Where Oppportunity = oppid AND Field IN

[Select NewValue, Oldvalue FROM Opportunity FieldHistory WHERE Opportunityld = :oppId AND Field IN

('StageName', Probability',Amount /CloseDate')];

[Select Amount CloseDate. StageName, Probability FROM Opportunity_History WHERE Opportunityld - :oppId];

SELECT Contact_c From order_c Where id NOT IN (SELECT id FROM_c Where States_c + Fulfilled')

SELECT iD FROM Contact WHERE id NOT IN (SELECT id From order_c WHERE_c = Fulfilled')

SELECT Contact_c FROM Order_c Where Status_c <> ;Fulfilled'

SELECT id FROM Contact WHERE id NOT IN (SELECT Contact _c FROM order_c Where Status_c = fulfilled')

86. What is the transaction limit for the number of SOSL queries?

What is the most effective approach to ensure values displayed respect the users locale settings?

Use the FOR VIEW clause in the SOQL Query.

Use REGEX expressions to format the values retrieved via SOQ

Use the FORMAT() function in the SOQL query.

Use a wrapper class to format the values retrieved via SOQ

92. A developer has requirement to query three fields (id, name, Type) from an Account and first and last names for all Contacts associated with the Account.

Which option is the preferred optimized method to achieve this for the Account named ‘Ozene Electronics’?

Account a = (SELECT ID, Name, Type from Account where name= Ozone Electronics;) list 1contacts = (SELECT firstname, lastname from Contacts where accountid=: a -ID0;

Account a = (SELECT ID, Name, Type, (select contat,firstName, Contact,LastName from Account, Contacts) from Account where name; Ozone Electronic' Limit 1 );

List 1Accounts = (Select ID, Name, Type from Account Join (Select ID, firstname, lastname form Contact where contact account , name 'ozone electronics));

List 1Contacts = new list ( ); for(Contact c ; 1Select firstname, lastname Account, Name Account,ID Account, Type from Contact where Account: Name=' electronics')) ( iContacts.add(c);)

93. Given the following code:

Assuming there were 10 Contacts and five Accounts created today, what is the expected result?

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

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.

97. After a Platform Event is defined in a Salesforce org, events can be published via which two mechanisms? Choose 2 answers

internal Apps can use Outbound Messages

Internal Apps can use Process Builder.

External Apps require a custom Apex web service.

External Apps can use the standard Streaming AP
