Which of the following file types must be monitored by a change-detection mechanism (for example, a file- integrity monitoring tool)?
- A. Application vendor manuals
- B. Files that regularly change
- C. Security policy and procedure documents
- D. System configuration and parameter files
Answer: D
Explanation:
Scope of Change-Detection Mechanisms
* PCI DSS v4.0 requires the implementation of a change-detection mechanism (e.g., file-integrity monitoring) to monitor unauthorized changes to critical files.
* Critical files include system configuration and parameter files, application executable files, and scripts used in administrative functions.
Intent of Monitoring System Files
* These files often control security settings and operational parameters of systems within the Cardholder Data Environment (CDE). Unauthorized changes could compromise system security.
Exclusions
* Documents like application vendor manuals and security policies do not qualify as files requiring integrity monitoring since they do not directly impact the security posture or operational functions of systems in the CDE.

Which statement about the Attestation of Compliance (AOC) is correct?
- A. The AOC must be signed by both the merchant/service provider and by PCI SSC.
- B. The same AOC template is used W ROCs and SAQs.
- C. There are different AOC templates for service providers and merchants.
- D. The AOC must be signed by either the merchant/service provider or the QSA/ISA.
Answer: C
Explanation:
Attestation of Compliance (AOC):
* The AOC is a document that confirms an entity's compliance with PCI DSS requirements. It is signed by the entity (merchant or service provider) and the Qualified Security Assessor (QSA) if a QSA is involved.
Different AOC Templates:
* PCI DSS provides distinct templates for service providers and merchants, tailored to their respective roles and responsibilities within the cardholder data environment (CDE).
Invalid Options:
* B:PCI SSC does not sign AOCs; they are signed by the merchant/service provider and the QSA.
* C:AOCs differ between ROCs and SAQs, so the same template is not universally used.
* D:Both the merchant/service provider and the QSA/ISA (Internal Security Assessor) must sign the AOC when applicable.
