To reduce the unavailability of a critical internally-hosted web service noticed in the service status reports, two practical solutions would be: A. Modify the code to include a try/catch block around the request to the external service. This approach ensures that even if the service is unavailable, the application can handle the error gracefully and continue functioning, possibly with a fallback mechanism. C. Increase the web service timeout. This allows the service more time to respond before the request is considered failed. It can be particularly useful if the service unavailability is due to delays in response rather than outright outages.

Both these strategies are recommended in handling external service interactions to ensure robustness and resilience in the application. They are supported by standard programming practices and Salesforce Commerce Cloud's guidelines on external integration.

To optimize controller performance by lazy loading scripts as needed, the best approach in a Salesforce Commerce Cloud environment is to use the require() method. This method allows scripts to be loaded dynamically at the time they are needed rather than at the start of the code execution, which can significantly improve performance by reducing the initial load time and resource consumption. The require() method is part of the CommonJS module specification implemented in the Rhino JavaScript engine used by Salesforce B2C Commerce. This method provides a standard way to include modular JavaScript files as needed during runtime, as detailed in the "Managing Scripts with require()" section of the Salesforce Commerce Cloud documentation.

If a developer is unable to view attributes of a custom object in the Business Manager of Salesforce B2C Commerce, a probable solution is to create an Attribute Group and include the desired attributes within this group. Attribute Groups help organize and manage attributes within Business Manager, making them more accessible and easier to handle. By grouping related attributes together, it becomes easier to manage their visibility and configuration, particularly in complex implementations with many custom attributes. This organization aids in ensuring that attributes are properly displayed and editable within the Business Manager interface.
