Under Appendix A.1, which statement is true about hosting providers?

• A. Hosting providers are fully responsible for PCI DSS compliance for all clients.
• B. The compliance of the hosting provider guarantees client PCI DSS compliance.
• C. A hosting provider must fulfill A.1 through A.1.4 and other PCI DSS requirements, but client compliance is not guaranteed.
• D. Hosting providers are exempt from PCI DSS obligations.

Answer: (C)

The important idea here is the shared responsibility model for hosting providers under PCI DSS. A hosting provider must meet the specific hosting-related requirements in Appendix A.1 (A.1 through A.4) and the broader PCI DSS rules for securing its own environment. However, this does not automatically make the client compliant. The client is still responsible for securing its own cardholder data, applications, and any systems it owns within or connected to the provider’s environment. The provider’s PCI DSS compliance can help reduce risk and may scope the client’s environment differently, but it does not guarantee that the client's own PCI DSS requirements are fully met. That’s why the statement that best fits is that the hosting provider must fulfill those hosting-specific requirements and others, but client compliance is not guaranteed by the provider’s compliance. The other options misstate the relationship: providers aren’t fully responsible for all clients’ compliance, the provider’s compliance doesn’t automatically certify the client, and providers are not exempt from PCI DSS duties when they handle or impact cardholder data.
