Which of the following is NOT a focus area of PCI DSS?

The focus areas of the Payment Card Industry Data Security Standard (PCI DSS) are clearly defined to protect cardholder data and ensure the security of payment card transactions. The correct choice highlights that capturing customer feedback is not included in these focus areas.

The PCI DSS is specifically structured around several key principles, which include the protection of cardholder data, maintaining a secure network, implementing strong access control measures, and regularly monitoring and testing networks. These principles are essential for organizations that handle payment card transactions to ensure their systems are secure and compliant with industry standards.

Capturing customer feedback, while valuable for improving services and understanding customer experiences, does not directly contribute to the security of payment card information or compliance with PCI DSS requirements. Therefore, it falls outside the scope of what PCI DSS addresses.

In contrast, the other options directly pertain to the efforts and standards required by PCI DSS to safeguard sensitive information, ensuring that organizations protect cardholder data effectively and maintain a secure environment for payment card transactions.
