Which is NOT a component of an e-commerce infrastructure?

The correct choice highlights that physical security cameras are not a fundamental component of an e-commerce infrastructure. E-commerce infrastructures primarily consist of technology and systems that facilitate online transactions, manage data, and ensure secure communication between various components.

Application servers are essential because they host the software applications that drive the user experience, allowing customers to browse and make purchases. Database servers are crucial for storing and managing customer information, product data, and transaction records, thus enabling the functionality of an e-commerce platform. Networking devices play a vital role in connecting all components of the infrastructure, ensuring seamless communication between servers, client devices, and external networks.

While physical security cameras are important for securing a physical location, such as a data center or office, they do not directly contribute to the online transactional capabilities or the functioning of e-commerce platforms. Therefore, they are considered an auxiliary security measure rather than a core component of the e-commerce infrastructure itself.
