Which of the following is included in e-commerce supporting infrastructure?

The correct answer encompasses the entirety of the components necessary for an effective e-commerce supporting infrastructure. In a modern e-commerce environment, multiple server types play critical roles. Web servers handle HTTP requests, delivering web pages to users. Application servers manage the business logic and application processes, interacting with the web servers. Database servers store and retrieve data, such as product information and customer details, which is essential for transaction workflows.

In addition to these servers, networking equipment like routers directs the data traffic efficiently, ensuring that requests are correctly routed to their destination. Firewalls provide security by controlling incoming and outgoing network traffic based on predetermined security rules, protecting against unauthorized access. Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IDP) monitor network traffic for suspicious activity, further securing the environment against threats.

Collectively, these components create a robust and secure architecture required to support e-commerce operations, ensuring that all aspects of data transmission, user interaction, and transaction management are handled effectively and securely. This comprehensive approach is what makes the correct answer the most accurate choice.
