Which code statement includes an Apex method named updateaccounts in the class accountcontreoller for use in a Lightning web component?

  • A. import updatelccounts from '@aalesforce/apeax/AccountController':
  • B. import updateiccounta from 'AccountConctroller':
  • C. import updatelccounta from 'RAccountContraller,updateiccounta';
  • D. import updase'Accounts from

Answer: D

Explanation:
'@=salesforce/apex/AccountController ., updateaccounts';
Explanation:
When importing an Apex method into a Lightning Web Component (LWC), the correct syntax is:
import methodName from '@salesforce/apex/ClassName.methodName';
Option D: import updateAccounts from '@salesforce/apex/AccountController.updateaccounts'; Correct Syntax.
import updateAccounts:
Specifies the JavaScript function name to reference in the LWC.
from '@salesforce/apex/AccountController.updateaccounts';:
Indicates that we are importing from an Apex class named AccountController, and the method is updateaccounts.
Case Sensitivity:
The class and method names are case-sensitive and should match the Apex code.
Reference:
Importing Apex Methods
Apex Methods in Lightning Web Components
Incorrect Options:
Option A: import updateaccounts from '@salesforce/apeax/AccountController'; Incorrect Module Path:
Misspelling in the module path (apeax instead of apex).
Missing Method Reference:
Does not specify the method to import.
Option B: import updateaccounts from 'AccountController';
Incorrect Module Path:
Missing the @salesforce/apex/ prefix.
Reference to Class Only:
Does not specify the method to import.
Option C: import updateaccounts from 'c/AccountController.updateaccounts'; Incorrect Namespace:
'c/' is used for importing custom JavaScript modules, not Apex methods.
Incorrect Module Path:
Should use @salesforce/apex/ for Apex methods.
Conclusion:
The correct code statement is Option D, which follows the proper syntax for importing an Apex method into an LWC.


NEW QUESTION # 151
Which three resources in an Aura component can contain JavaScript functions? Choose 3 answers

  • A. Renderer
  • B. Helper
  • C. style
  • D. Controller
  • E. Design

Answer: A,B,D

Explanation:
In an Aura component, JavaScript functions can be included in the following resources:
Controller (.js file):
Handles events triggered by user interaction or component lifecycle.
Contains action handlers defined in the component's markup.
"A client-side controller contains the handler functions that are called in response to events fired by the component or other components."
- Aura Components Developer Guide: Client-Side Controller
Helper (.js file):
Contains reusable functions that can be called from the controller or renderer.
Helps to keep the controller lean by abstracting complex logic.
"A helper JavaScript resource can be added to an Aura component bundle and is used to store helper functions that can be reused in the component's client-side code."
- Aura Components Developer Guide: Helper Functions
Renderer (.js file):
Allows for custom rendering behavior.
Contains methods that can override default rendering lifecycle events.
"A renderer component bundle resource allows you to customize the rendering behavior of a component."
- Aura Components Developer Guide: Custom Renderers
Why Other Options Are Incorrect:
C . Style:
The .css file in an Aura component is used for styling and cannot contain JavaScript functions.
"An Aura component or application can have a style (CSS) resource to define its styles."
- Aura Components Developer Guide: Style
E . Design:
The .design file is used to define metadata values for the component, especially when used in Lightning App Builder or Community Builder.
"A design resource describes the design-time behavior of an Aura component-information that visual tools need to display the component in a page or app."
- Aura Components Developer Guide: Design Files
Conclusion: JavaScript functions in an Aura component can be placed in the Controller, Helper, and Renderer resources. Therefore, the correct answers are A, B, and D.


NEW QUESTION # 152
A developer completed modifications to a customized feature that is comprised of two elements:
* Apex trigger
* Trigger handler Apex class
What are two factors that the developer must take into account to properly deploy the modification to the production environment?
Choose 2 answers

  • A. At least one line of code must be executed for the Apex trigger.
  • B. Apex classes must have at least 75% code coverage org-wide.
  • C. All methods in the test classes must use @isTest.
  • D. Test methods must be declared with the testMethod keyword.

Answer: A,B

Explanation:
When deploying Apex code to a production environment, certain requirements must be met regarding test coverage and annotations.
Option B: Apex classes must have at least 75% code coverage org-wide.
Correct Requirement.
Salesforce requires that all Apex classes and triggers have a combined code coverage of at least 75% before deployment to production.
This means that, across all Apex code in the org, at least 75% of the code must be covered by test methods.
Every trigger must have some test coverage, even if the overall code coverage is above 75%.
Specifically, triggers must have at least 1% code coverage.
Test methods should be annotated with @isTest.
However, it's not mandatory that all methods in a test class use @isTest; helper methods within test classes can be private or public methods without the annotation.
Only the test methods themselves need the @isTest annotation.
The testMethod keyword is deprecated but still supported.
The preferred approach is to use the @isTest annotation.
Using testMethod is not recommended for new code.
Reference:
Code Coverage Requirement
Option D: At least one line of code must be executed for the Apex trigger.
Correct Requirement.
Trigger Coverage Requirement
Options Not Suitable:
Option A: All methods in the test classes must use @isTest.
Partially Correct.
Defining Test Methods
Option C: Test methods must be declared with the testMethod keyword.
Outdated Practice.
Deprecated testMethod Keyword
Conclusion:
The two factors the developer must take into account are B (75% code coverage org-wide) and D (At least 1% coverage for triggers).
These are mandatory requirements for deploying Apex code to production.
