NEW QUESTION # 158
A developer must perform a complex SOQL query that joins two objects in a Lightning component.
How can the Lightning component execute the query?
Answer: A
Explanation:
When a Lightning component needs to execute a complex SOQL query that joins two objects, and such queries are not supported directly in Lightning components, the solution is to use an Apex controller method.
Option C: Invoke an Apex class with the method annotated as @AuraEnabled to perform the query.
Correct Approach.
The Lightning component can call an Apex method annotated with @AuraEnabled.
The Apex method can perform the complex SOQL query and return the results to the component.
While it's possible to invoke flows from Lightning components, flows are not ideal for executing complex SOQL queries.
Flows have limitations on data manipulation and querying.
Option B: Write the query in a custom Lightning web component wrapper and invoke from the Lightning component.
Not Applicable.
Lightning components (Aura or LWC) cannot execute complex SOQL queries directly.
They must call server-side Apex methods for such operations.
Option D: Use the Salesforce Streaming API to perform the SOQL query.
Incorrect.
The Streaming API is used for subscribing to data changes in real-time.
It is not used for executing queries.
Conclusion:
The Lightning component should invoke an Apex method annotated with @AuraEnabled to perform the complex SOQL query, which is Option C.
Reference:

Using Apex to Get Data
Incorrect Options:
Option A: Create a flow to execute the query and invoke from the Lightning component.
Not Optimal.
NEW QUESTION # 159
Which code statement includes an Apex method named updateAccounts in the class AccountController for use in a Lightning web component?
Answer: B
Explanation:
* When working with a Lightning Web Component (LWC), the correct syntax for importing an Apex method is:import methodName from "@salesforce/apex/ControllerName.methodName";.
Why not other options?
* A, B, and C: These use incorrect syntax for importing Apex methods in LWCs.
References:
* Lightning Web Components Documentation
NEW QUESTION # 160
What are three ways for a developer to execute tests in an org?
Choose 3 answers
Answer: A,C,E
Explanation:
There are several ways to execute tests in a Salesforce org:
Option A: Setup Menu
Valid Method.
Tests can be run from the Salesforce Setup menu under Apex Test Execution.
Allows selecting and running test classes and methods.
The Tooling API allows programmatic execution of Apex tests.
Useful for integrating with external tools or CI/CD pipelines.
Salesforce DX (SFDX) CLI allows running tests via command line.
Commands like sfdx force:apex:test:run can execute tests.
The Metadata API is used for deploying and retrieving metadata (like Apex classes).
It is not used to execute tests directly.
The Bulk API is used for loading or querying large volumes of data.
It is not related to executing Apex tests.
Reference:
Running Apex Tests in Salesforce Setup
Option B: Tooling API
Valid Method.
Tooling API Developer Guide
RunTestsAsynchronous
Option D: Salesforce DX
Valid Method.
Salesforce CLI Command Reference
Incorrect Options:
Option C: Metadata API
Not Used for Executing Tests.
Metadata API
Option E: Bulk API
Not Used for Executing Tests.
Bulk API Guide
Conclusion:
The three ways a developer can execute tests are A (Setup Menu), B (Tooling API), and D (Salesforce DX).
NEW QUESTION # 161
A developer creates a Lightning web component that imports a method within an Apex class. When a Validate button is pressed, the method runs to execute complex validations.
In this implementation scenario, which two options are.. of the Controller according to the MVC architecture?
Choose 2 answers
Answer: A,B
Explanation:
In the context of the MVC (Model-View-Controller) architecture for a Lightning Web Component (LWC), the Apex class and JavaScript file are responsible for handling the controller's role:
Apex Class (Controller):
Acts as the server-side controller.
Executes business logic, such as the complex validations mentioned in the scenario.
Exposes methods for the LWC to call using@AuraEnabled.
Reference:https://developer.salesforce.com/docs/component-library/documentation/en/lwc/lwc.apex JavaScript File (Controller):
Acts as the client-side controller.
Manages the interaction between the HTML (View) and Apex methods.
Executes functions triggered by user actions, such as clicking the "Validate" button.
Reference:https://developer.salesforce.com/docs/component-library/documentation/en/lwc/lwc.
js_props_methods
Why Not the Other Options?A. HTML file: Represents the "View" in MVC, focusing on UI rendering.
D). XML file: Used for metadata configuration and is not part of the controller functionality.
NEW QUESTION # 162
A developer needs to confirm that a Contact trigger works correctly without changing the organization ' s data.
What should the developer do to test the Contact trigger?
Answer: C
Explanation:
Answer D is correct. Salesforce delivery depends on repeatable testing and controlled deployment. Apex tests create isolated data, validate behavior, and supply code coverage for production deployment. Salesforce CLI, scratch orgs, sandboxes, debug logs, trace flags, and Apex Jobs give developers the tooling needed to build, test, diagnose, and release changes across environments. The other options either use the wrong platform feature, apply at the wrong layer, or ignore a key Salesforce constraint. For Platform Developer I, the important point is not just syntax; it is choosing the feature that aligns with transaction behavior, security enforcement, maintainability, and supported metadata capabilities. Reference focus: Salesforce Apex Developer Guide, Salesforce CLI Developer Guide, Tooling API documentation, and Salesforce Help deployment guidance. This distinction is important in production orgs because small design mistakes can create deployment failures, runtime exceptions, data-quality defects, or user-visible security gaps once automation is executed in bulk or from multiple entry points.
