NEW QUESTION # 40
A developer wrote Apex code that calls out to an external system using REST API.
How should a developer write the test to prove the code is working as intended?

• A. write a class that implements HTTPCalloutMock.
• B. Write a class that extends HTTPCalloutMock.
• C. Write a class that extends WerServiceMack.
• D. Write a class that implements WebServiceMock.

Answer: A

Explanation:
When writing tests for Apex code that performs callouts to external services, Salesforce requires that callouts are mocked to ensure that tests do not depend on external systems and to allow for consistent and predictable test results.
Correct Option:
Option D: Write a class that implements HttpCalloutMock.
True.
To test HTTP callouts, you implement the HttpCalloutMock interface and provide a fake response for the HTTP request.
This mock response is then used in your test methods to simulate the callout.
The test method uses Test.setMock to set the mock class.
WebServiceMock is used for testing SOAP callouts, not REST (HTTP) callouts.
Since the code uses REST API, HttpCalloutMock is appropriate.
HttpCalloutMock is an interface, not a class. You cannot extend an interface; you implement it.
The correct approach is to implement the HttpCalloutMock interface.
Reference:
Testing HTTP Callouts by Implementing HttpCalloutMock
Incorrect Options:
Option A & C: Write a class that implements or extends WebServiceMock.
False.
Testing SOAP Callouts
Option B: Write a class that extends HttpCalloutMock.
False.
Interface vs. Class
Conclusion:
To properly test REST API callouts in Apex, you should write a class that implements HttpCalloutMock and use it in your test methods.

Universal Containers implemented a private sharing model for the Account object. A custom Account search tool was developed with Apex to help sales representatives find accounts that match multiple criteria they specify. Since its release, users of the tool report they can see Accounts they do not own.
What should the developer use to enforce sharing permissions for the currently logged in user while using the custom search tool?

• A. Use the with sharing keyword on the class declaration.
• B. Use the without sharing keyword on the class declaration.
• C. Use the userInfo Apex class to filter all SOQL queries to returned records owned by the logged-in user.
• D. Use the schema describe calls to determine if the logged-in user has access to the Account object.

Answer: A

Explanation:
The with sharing keyword ensures that the Apex class respects the sharing rules of the current user, including private sharing models. This means the logged-in user will only see records they own or have been shared with them.

NEW QUESTION # 44
In terms of the MVC paradigm, what are two advantages of implementing the view layer of a Salesforce application using Lightning Web Component-based development over Visualforce?
Choose 2 answers

• A. Log capturing via the Debug Logs Setup page
• B. Rich component ecosystem
• C. Built-in standard and custom set controllers
• D. Self-contained and reusable units of an application

Answer: B,D

Explanation:
When comparing Lightning Web Components (LWC) with Visualforce for the View layer in the MVC paradigm, several advantages stand out.
Option A: Self-contained and reusable units of an application
Correct Advantage.
LWCs are built using modular components that encapsulate their own structure, style, and behavior.
Components can be reused across different parts of the application, promoting consistency and reducing development time.
This modularity allows for better maintainability and scalability.
LWC leverages modern web standards and offers a rich set of base components provided by Salesforce.
Developers can use pre-built components for common functionalities, speeding up development.
The ecosystem is continuously expanding, with contributions from Salesforce and the community.
Debug logs are a feature of Salesforce that applies to both Visualforce and LWC.
This is not an advantage specific to LWC in the context of the View layer.
Option D: Built-in standard and custom set controllers
Advantage of Visualforce.
Visualforce provides built-in standard controllers and allows for custom controllers and controller extensions.
In LWC, controllers are written in JavaScript, and data access is typically done via Apex methods.
This is an area where Visualforce has more built-in support.
Conclusion:
The two advantages of using Lightning Web Components over Visualforce in the View layer are:
Option A: Self-contained and reusable units of an application.
Option C: Rich component ecosystem.
These advantages stem from LWC's modern architecture and adherence to web standards, enabling more efficient and modular development.
Reference:

Option C: Rich component ecosystem
Correct Advantage.

Options Not Applicable:
Option B: Log capturing via the Debug Logs Setup page
Not a View Layer Advantage.

NEW QUESTION # 45
A developer creates a batch Apex job to update a large number of records, and receives reports of the job timing out and not completing.
What is the first step towards troubleshooting the issue?

• A. Decrease the batch size to reduce the load on the system.
• B. Disable the batch job and recreate it with a smaller number of records.
• C. Check the asynchronous job monitoring page to view the job status and logs.
• D. Check the debug logs for the batch job.

Answer: C

Explanation:
When a batch Apex job is timing out and not completing, the first step in troubleshooting is to check the job's status and logs in the Asynchronous Job Monitoring page. This page provides information about all asynchronous Apex jobs, including batch Apex, scheduled Apex, future methods, and queueable Apex.
Option D: Check the asynchronous job monitoring page to view the job status and logs.
Correct Approach.
The Asynchronous Job Monitoring page (also known as the Apex Jobs page) in Salesforce Setup allows developers to see the status of all asynchronous Apex jobs.
By checking this page, the developer can see whether the batch job is still running, failed, or completed.
If the job has failed, the page provides error messages that can help identify the cause of the failure.
This is the first step to determine what is happening with the batch job.
While checking the debug logs can provide detailed information, it is more efficient to first check the job status on the asynchronous job monitoring page.
Debug logs can be large and may not be generated if the job did not execute properly.
After identifying the job's status and any error messages, the developer can then decide if checking debug logs is necessary.
Option C: Decrease the batch size to reduce the load on the system.
Possible Solution, Not First Step.
Decreasing the batch size may help prevent timeouts by processing fewer records at a time.
However, before making changes to the batch job, the developer should first investigate the cause of the timeout.
Option A: Disable the batch job and recreate it with a smaller number of records.
Not Recommended as First Step.
Disabling and recreating the batch job without understanding the issue may not resolve the problem.
It's important to diagnose the issue before making changes.
Conclusion:
The first step towards troubleshooting a batch Apex job that is timing out is to check the asynchronous job monitoring page to view the job's status and any error messages.
This provides immediate insight into what is happening with the job and guides the next steps in troubleshooting.

Apex Jobs Page
Option B: Check the debug logs for the batch job.
Next Step, Not First Step.

NEW QUESTION # 49
A developer Is designing a new application on the Salesforce platform and wants to ensure it can support multiple tenants effectively.
Which design framework should the developer consider to ensure scalability and maintainability?

• A. Model-View-Controller (MVC)
• B. Agile Development
• C. Flux (view, action, dispatcher, and store)
• D. Waterfall Model

Answer: A

Explanation:
When designing a new application on the Salesforce platform that needs to support multiple tenants effectively (i.e., multiple customers or users), the developer should consider the Model-View-Controller (MVC) framework.
Option B: Model-View-Controller (MVC)
Correct Design Framework.
MVC is a software architectural pattern for implementing user interfaces.
Model: Represents the data and business logic.
View: Represents the presentation layer.
Controller: Handles user input and interactions.
Salesforce's platform follows the MVC pattern, which helps in separating concerns, ensuring scalability, and maintainability.
Agile is a methodology for managing projects, not a design framework.
It does not directly address scalability or maintainability.
Option C: Flux (view, action, dispatcher, and store)
Not Commonly Used in Salesforce.
Flux is an application architecture used by Facebook for building client-side web applications.
It is not a standard design pattern in Salesforce development.
Option D: Waterfall Model
Development Methodology, Not a Design Framework.
Waterfall is a linear and sequential approach to software development.
It does not specifically help with scalability and maintainability in multi-tenant environments.
Conclusion:
The developer should consider the Model-View-Controller (MVC) framework, which is Option B.
