B2C-Commerce-Developer Exam Dumps : Salesforce Certified B2C Commerce Developer (WI25)

In Salesforce Commerce Cloud's Storefront Reference Architecture (SFRA), the recommended way to enhance the functionality of an existing controller route without altering the original code is to use the "extend" method provided by the server module. This method allows developers to extend an existing route and add or modify its functionality by adding additional processing or modifying viewData. This approach keeps the base controller intact and ensures that the customization is isolated, which simplifies updates and maintenance. By using "extend", the original route remains unchanged, and new functionality is layered on top of it, which aligns with best practices for modularity and maintainability in software development.

The correct place to implement CSRF (Cross-Site Request Forgery) protection validation is: C. In the controller function that handles the submitted form - When the form is submitted, the controller function that processes the form data should include a check for a valid CSRF token. This is typically done using the validateRequest or validateAjaxRequest method depending on the nature of the request (synchronous or asynchronous). By performing this validation in the controller function that handles the form submission, it ensures that the form data is protected against CSRF attacks, which is a critical security measure for forms that perform changes to server-side data.

In Salesforce B2C Commerce, encountering a quota limit typically suggests that a certain resource or operation limit set in Business Manager is being exceeded. This could be API calls, bandwidth, or CPU usage, among others. The best approach is to address the root cause of the quota overage. Rewriting or optimizing the code to reduce resource consumption or the frequency of operations can help stay within the quota limits. Changing configuration settings or removing limits might not always be possible due to governance or performance stability reasons. Taking no action could lead to continued interruptions in service or functionality. Therefore, the most effective and sustainable solution is to modify the code to adhere to established quotas.
