Accepted Answer

Create custom metadata types for each environment and use the Metadata API to deploy the records between environments.

Question 20

In the context of developing a responsive web application for an e-commerce platform, a developer is tasked with ensuring that the layout adapts seamlessly across various devices, including desktops, tablets, and smartphones. The developer decides to implement a fluid grid layout combined with media queries. Which approach best exemplifies the principles of responsive design in this scenario?

Accepted Answer

Utilizing relative units like percentages for widths and applying media queries to adjust styles based on device characteristics.

Question 21

In a retail application utilizing an event-driven architecture, a customer places an order which triggers several events: an inventory check, a payment processing request, and a notification to the shipping department. If the inventory check fails due to insufficient stock, which of the following best describes the implications for the subsequent events and the overall system behavior?

Question 23

In a Lightning App Development scenario, a developer is tasked with creating a custom Lightning component that displays a list of accounts filtered by a specific industry. The component must also allow users to sort the accounts by their annual revenue. The developer decides to use a combination of Apex and Lightning Web Components (LWC) to achieve this. Which approach should the developer take to ensure optimal performance and maintainability of the component while adhering to best practices?

Accepted Answer

Use an Apex controller to fetch the accounts based on the selected industry and return the results as a JSON object, then use LWC to handle the sorting and rendering of the data on the client side.

Question 24

In a Salesforce application, you have created an invocable method within an Apex class that is designed to process a list of account records. The method takes a list of account IDs as input and returns a list of account names. You want to ensure that this method can be called from a Flow and that it handles exceptions gracefully. Which of the following best describes how to implement this invocable method to meet these requirements?

Accepted Answer

The method should be annotated with `@InvocableMethod`, accept a list of `String` as input, and return a list of `String`. Additionally, it should include a try-catch block to handle exceptions and return an empty list if an error occurs.

Question 25

In a Salesforce application, a company has implemented a custom user authentication mechanism that utilizes OAuth 2.0 for user login. The application requires users to authenticate using their corporate credentials, which are stored in an external identity provider (IdP). After successful authentication, the IdP returns an access token to the Salesforce application. The application needs to ensure that users have the appropriate permissions to access specific resources based on their roles. Given this scenario, which of the following best describes the process of validating user permissions after authentication?

Accepted Answer

The application should decode the access token to extract user roles and permissions, then compare these against the required permissions for the requested resource.

Question 26

A company is developing a new application that integrates with Salesforce using the REST API. The application needs to retrieve a list of accounts based on specific criteria, including the account type and the date the account was created. The developer decides to use a SOQL query to filter the results. Which of the following statements best describes how to structure the REST API call to achieve this?
