Salesforce Certified Platform Developer II - Multiple Choice Sample Questions (Q202-Q207):

NEW QUESTION # 202
Refer to the markup below:

A Lightning web component displays the Account name and two custom fields out of 275 that exist on the abject. The custom fields are correctly declared and populated. However, the developer receives complaints that the component performs slowly. What can the developer do to improve the performance?

A. Add cache="true" to the component.
B. Replace layout-type =''1" with fields=(fields}.
C. Replace Layout-type =''Full1" with Layout-type="Partial".
D. Add density="compat" to the component.

Answer: B

Explanation:
To improve performance, the developer should specify only the fields needed by using the fields attribute in the lightning-record-form instead of loading all fields with layout-type="Full". This reduces the amount of data being retrieved and processed, thus improving the component's performance.

NEW QUESTION # 203
Universal Containers develops a Salesforce application that requires frequent interaction with an external REST API.
To avoid duplicating code and improve maintainability, how should they implement the APL integration for code reuse?

A. Create a reusable Apex class for the AFL integration and invoke it from the relevant Apex classes.
B. Use a separate Apex class for each API endpoint to encapsulate the integration logic,
C. Store the APT integration code as a static resource and reference it in each Apex class.
D. Include the API integration code directly in each Apex class that requires it.

Answer: A

Explanation:
Creating a reusable Apex class for API integration allows for code encapsulation and maintainability. This class can then be invoked from any other Apex class that requires interaction with the API, preventing code duplication.

NEW QUESTION # 204
Business rules require a Contact ta always be created when a new Account is created.
What can be used when developing a custom screen to ensure an Account is not created if the creation of the Contact fails?

A. Use setSaverpoint (1) and rollback() with a try-catch block.
B. Disable validation rules on Contacts and set default values with a trigger.
C. Use the Database. Insect method with a11orNone SEL LO alee,
D. Use the Database. Delete method if the Contact insertion fails.

Answer: A

Explanation:
When developing a custom screen that requires both an Account and Contact to be created together, using setSavepoint() and rollback() within a try-catch block is a reliable way to ensure that if the Contact creation fails, the Account creation is also rolled back, maintaining data integrity.

NEW QUESTION # 205
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.

The callousUtil.makeRestCallout fails with a "You have uncommitted work pending. Please commit or rollback before calling cut' error. What should be done to address the problem?

A. Change the callousUtil makeRestCallout to an @InvocsblsMethod method.
B. Remove the Database. setSavepoint and Database. rollback.
C. Change the CallousUtill .makeRestCallout to an @future method.

Answer: C

Explanation:
The error occurs because DML operations were performed before a callout. To fix this, the callout should be made from an asynchronous method such as one annotated with @future(callout=true), which allows DML operations to be committed separately from the callout.

NEW QUESTION # 206
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?

A. Add a teardown block to reset the DOM after each test.
B. Create a new jsdom instance for each test.
C. Reset the DOM after each test with the after Each() method.
D. Create a new describe block for each test.

Answer: C

Explanation:
To ensure that the DOM is clean before each test runs, the developer should use the afterEach() method to reset it. This is part of the setup and teardown process in Jest tests, which helps to avoid state leakage between tests. Reference:
Jest Globals afterEach
