For configuring permissions for an Open Commerce API resource, the essential properties needed are: A. Resource_id - This property specifies the identifier for the resource you wish to configure, which is crucial for defining the scope and target of the API permissions. C. Client_id - This property identifies the specific client application that the permissions apply to. It is essential for controlling which client applications have access to the specified resource. These properties ensure that permissions are correctly assigned both to the resource and to the client application accessing it, aligning with security and access management practices in Salesforce B2C Commerce.

To import a site export file into a sandbox, the recommended method involves using the Site Import & Export Business Manager module:

Option B: Upload and import the file using the local option within the Site Import & Export Business Manager module is the correct answer. This option allows the developer to upload a site export file directly through the Business Manager interface and then import it into the sandbox. This is the most straightforward and typical method for updating sandbox environments with new data or configurations.

Other options like connecting remotely (A), using the Impex WebDAV directory (C), or using the Static WebDAV directory (D) are either incorrect methods or involve incorrect directories for site import activities.

To add fault tolerance to a web service integration using the Service Framework in Salesforce B2C Commerce, and allowing for configurable timeouts and rate limiting, the best approach is to use site preferences for configuration settings and handle exceptions that might occur due to connectivity issues or timeouts.

Option C is correct because:

Creating a site preference to store timeout settings allows administrators to dynamically configure these parameters.

Implementing an IOException handler provides a direct way to handle network-related errors, which are common in web service integration, and execute fallback code when these errors occur.

Other options do not provide a comprehensive solution to configuring and handling errors based on administrative settings:

Implementing a ServiceUnavailableException handler (Option A) only addresses a specific type of error and does not allow for configurable settings.

Checking if the response was empty (Option B) does not address the main requirement of handling network issues and configurable timeouts.

Using the setTimeout method (Option D) is not a standard practice for handling errors in web service calls in this context.

QUESTIONNO: 45

A Digital Developer has been given a requirement to add fault tolerance to an existing web service integration that uses Service Framework. Administrators at Universal Containers need to be able to configure the timeout and rate limiting.

Which approach should the Developer use to implement the requirement?

A. Implement a ServiceUnavailableException exception handler to execute fallback code.

B. Implement a condition that checks to see if the response was empty and execute fallback code if true.

C. Create a site preference to store timeout settings and implement an IOException handler to execute fallback code.

D. Use the setTimeout method to execute fallback code if the request has NOT completed.

Answer: D

When cartridges are not executing despite being uploaded, it typically indicates an issue with how the server is configured to recognize and use the uploaded cartridges.

Option D, "Set the server connection’s target version directory to the active code version," is the correct action because it ensures that the server uses the correct set of cartridges (the ones uploaded) as part of the active code version. This setup is crucial for the proper execution of code on the Salesforce B2C Commerce server.

This option resolves the issue by linking the active development work (the uploaded cartridges) with the server's operational environment, ensuring that changes are recognized and executed as part of the active deployment.

Other options do not address the issue of ensuring that the uploaded cartridges are recognized and used in the active server environment:

Setting the active code version to use the latest compatibility mode (Option A) does not necessarily connect the uploaded cartridges with the server.

Removing invalid characters from the code version’s name (Option B) or cartridge file and folder names (Option C) addresses different potential issues unrelated to version targeting.

In SFRA (Salesforce Reference Architecture), when creating controller endpoints for client-side AJAX requests where updated information needs to be displayed without refreshing or changing the current page layout, the best method to use is res.json(). This method allows the controller to send JSON-formatted response data back to the client, which can be easily handled via JavaScript on the client side. This approach is optimal for asynchronous requests where data needs to be updated dynamically on the page as it does not involve re-rendering the entire page but rather just the relevant data components. This practice is consistent with modern web development standards that focus on enhancing user experience and reducing server load.
