PCI DSS Requirement 11.5 states that entities must deploy a change-detection mechanism (for example, file-integrity monitoring tools) to alert personnel to unauthorized modification of critical system files, configuration files, or content files; and configure the software to perform critical file comparisons at least weekly1. This is to ensure that any unauthorized or malicious changes to the files are detected and reported in a timely manner, and that the integrity and security of the files are maintained. Critical files are those that affect the security of the cardholder data environment (CDE), such as system files, application executables, configuration files, database files, and log files2. Therefore, the correct answer is option A.

The other options are not true regarding the frequency of critical file comparisons for a change-detection mechanism. Option B is not true because PCI DSS does not allow the entity to define the periodicity of the file comparisons, as it specifies a minimum frequency of at least weekly1. Option C is not true because PCI DSS does not limit the file comparisons to only after a valid change is installed, as it requires the file comparisons to be performed at least weekly regardless of the change status1. Option D is not true because PCI DSS does not allow the file comparisons to be performed at least monthly, as it requires a higher frequency of at least weekly1. References:

classifying media that contains cardholder data is intended to ensure that media is property protected according to the sensitivity of the data it contains, which means it should be markedwith labels or tags that indicate its level of confidentiality or integrity. This is one of the requirements for ensuring that media containing cardholder data is properly labeled.

The PCI DSS requires that access to databases containing cardholder data is restricted to authorized users and applications, and that direct access to such databases is prohibited. According to the PCI DSS Requirement 7.1.2, “Restrict access to privileged user IDs to least privileges necessary to perform job responsibilities.” Furthermore, according to the PCI DSS Requirement 8.3.1, “Implement multi-factor authentication for all non-console access into the cardholder data environment for personnel with administrative access.” Therefore, the scenario that meets the PCI DSS requirements for restricting access to databases containing cardholder data is the one where user access to the database is only through programmatic methods, such as through an application interface that enforces authentication, authorization, and encryption. The other scenarios either allow direct access to the database, or do not limit the access to the least privileges necessary, or do not use multi-factor authentication for administrative access. References: [PCI DSS v3.2.1], Card Production Security Assessor - Logical - Credly
