Salesforce B2C-Commerce-Developer Exam With Confidence Using Practice Dumps

To maintain state across server-side calls efficiently and in a scalable manner, the best practice is: B. Use the Session class in the B2C Commerce API - The Session class provides a server-side storage mechanism for storing user-specific data during a session. This is suitable for storing temporary data such as the authentication state, customer-related information, and privacy preferences securely and efficiently, without persisting sensitive information unnecessarily.

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, to manage the rate of calls made to external services and to prevent exceeding the limit of allowed calls, developers can configure a rate limiter directly in the service profile. This involves setting up specific thresholds that define the number of calls that can be made per second. This setup ensures that the integration adheres to external service limitations or internal performance considerations by controlling the rate at which requests are sent. The configuration of rate limiting is critical in environments where multiple calls are made to external APIs, which might have their own limitations on how often they can be accessed. This practice not only adheres to the best use of external services but also helps in maintaining the stability and performance of the application.
