Question 8

Universal Containers uses a custom Lightning page to provide a mechanism to perform a step-by-step wizard search for Accounts. One of the steps in the wizard is to allow the user to input text into a text field, ERF Number_c, that is then used in a query to find matching Accounts.

Which step should be taken to resolve the issue?

Options:

Perform the SOQL query as part of a for loop.

Mark the ERP_Numker = field as an external 10.

Mark the ERP_Number__ c field as required.

Move the SO0L query to within an asynchronous process.

Question 9

A developer is writing a Jest test for a Lightning web component that conditionally displays child components based on a user's checkbox selections.

What should the developer do to properly test that the correct components display and hide for each scenario?

Options:

Create a new describe block for each test.

Reset the DOM after each test with the after Each() method.

Add a teardown block to reset the DOM after each test.

Create a new jsdom instance for each test.

Question 10

Universal Containers wants to notify an external system in the event that an unhandled exception occurs when their nightly Apex batch job runs.

What is the appropriate publish/subscribe logic to meet this requirement?

Options:

Have the external system subscribe to a custom Platform Event that gets fired with addError{).

Have the external system subscribe to a custom

Platform Event that gets fired with EventBus.publish(1,

Have the external system subscribe to a standard

Platform Event that gets fired with with Eventbus.publish(1.

Have the external system subscribe to a standard Platform Event that gets fired.

Question 11

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 one 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?

Options:

There will be no error and all updates will succeed, since the limit on the number of records processed by DML statements was not exceeded.

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.

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.

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