- A. Security policy and procedure documents
- B. Files that regularly change
- C. Application vendor manuals
- D. System configuration and parameter files
Answer: D
Explanation:
PCI DSSRequirement 11.5.2mandates the use of file-integrity monitoring (FIM) or change-detection tools to monitorcritical filessuch as system binaries, configuration files, and system parameters.
* Option A:#Incorrect. Manuals are not critical system files.
* Option B:#Incorrect. Regularly changing files (e.g., logs or temp files) are typically excluded.
* Option C:#Incorrect. Policies and procedures are reviewed but not subject to FIM.
* Option D:#Correct. System config and parameter files must bemonitored for unauthorised changes.
NEW QUESTION # 37
Which scenario meets PCI DSS requirements for restricting access to databases containing cardholder data?
- A. Application IDs for database applications can only be used by database administrators.
- B. User access to the database Is restricted to system and network administrators.
- C. User access to the database Is only through programmatic methods.
- D. Direct queries to the database are restricted to shared database administrator accounts.
Answer: C
Explanation:
Restricting Database Access
* PCI DSS Requirement 7.2 specifies that access to cardholder data, including databases, must be restricted by business need-to-know.
* Restricting access to programmatic methods minimizes the risk of unauthorized queries and data breaches.
Eliminating Direct Access
* Direct database access by end-users or administrators poses significant risk unless strictly controlled and monitored. Programmatic methods (e.g., via applications with role-based access controls) align with security best practices.
Incorrect Options
* Option B: Administrators might need access, but access should not be limited to system/network administrators.
* Option C: Application IDs should not be used directly by individuals, as this circumvents accountability.
* Option D: Shared accounts are discouraged due to a lack of traceability.
NEW QUESTION # 38
In accordance with PCI DSS Requirement 10, how long must audit logs be retained?
- A. At least 2 years, with the most recent month immediately available.
- B. At least 1 year, with the most recent 3 months immediately available.
- C. At least 2 years, with the most recent 3 months immediately available.
- D. At least 3 months, with the most recent month immediately available.
Answer: B
Explanation:
PerRequirement 10.5.1.2, audit logs must be retained forat least one year, and the mostrecent three months must be readily availablefor analysis. This ensures traceability of security events over both short and longer- term periods.
* Option A:#Correct. Matches both duration and availability criteria.
* Option B:#Incorrect. Two years is not required.
* Option C:#Incorrect. The retention period is misstated.
* Option D:#Incorrect. One month is insufficient for immediate access.
NEW QUESTION # 39
An entity accepts e-commerce payment card transactions and stores account data in a database. The database server and the web server are both accessible from the Internet. The database server and the web server are on separate physical servers. What is required for the entity to meet PCI DSS requirements?
- A. The database server should be moved to a separate segment from the web server to allow for more concurrent connections.
- B. The web server and the database server should be installed on the same physical server.
- C. The database server should be relocated so that it is not accessible from untrusted networks.
- D. The web server should be moved into the Internal network.
Answer: C
Explanation:
Protecting the Database Server
* PCI DSS v4.0 requires that systems storing cardholder data, such as database servers, must not be directly accessible from untrusted networks (Requirement 1.3).
* The database server should be behind network security controls like firewalls and placed in a segmented network isolated from untrusted networks.
Segmentation Best Practices
* The web server, which interfaces with external users, can remain accessible from the Internet but should reside in a DMZ to prevent direct access to the internal network.
* This separation protects the database server from external threats while maintaining system functionality.
Incorrect Options
* Option A: Combining the web and database servers increases the attack surface and violates best practices.
* Option C: Moving the web server to the internal network exposes the internal environment.
* Option D: Segmentation is critical, but the reason is not solely to allow more concurrent connections.
NEW QUESTION # 40
Passwords for default accounts and default administrative accounts should be?
- A. Reset to the default password before installing a system on the network.
- B. Configured to expire in 30 days.
- C. Changed before installing a system on the network.
- D. Changed within 30 days after installing a system on the network.
Answer: C
Explanation:
According toRequirement 2.2.6,default passwords must be changed before systems are installed on the network. The use of default credentials (such as "admin/admin") presents a major security risk and is a well- known vector for breaches.
* Option A:#Incorrect. Changing within 30 days is not soon enough per PCI DSS.
* Option B:#Incorrect. Resetting to default would defeat the purpose of secure configuration.
* Option C:#Correct. The requirement is to change default passwordsprior to network connection.
* Option D:#Incorrect. Password expiration policies are a separate topic under Requirement 8.

NEW QUESTION # 41
Viewing of audit log files should be limited to?
- A. Individuals with read/write access.
- B. Individuals who performed the logged activity.
- C. Individuals with a job-related need.
- D. Individuals with administrator privileges.
Answer: C
Explanation:
Audit Log Access Control:
* PCI DSS Requirement 10.7 restricts access to audit logs to individuals with a job-related need to protect the integrity and confidentiality of the logs.
Rationale for Job-Related Need:
* Limiting access reduces the risk of tampering, accidental modification, or exposure of sensitive information.
Invalid Options:
* A:Individuals who performed the activity should not necessarily view logs unless required.
* B/C:Read/write access or administrator privileges are not prerequisites for log viewing.
NEW QUESTION # 42
Which scenario describes segmentation of the cardholder data environment (CDE) for the purposes of reducing PCI DSS scope?
- A. Firewalls that log all network traffic flows between the CDE and out-of-scope networks.
- B. Virtual LANs that route network traffic between the CDE and out-of-scope networks.
- C. A network configuration that prevents all network traffic between the CDE and out-of-scope networks.
- D. Routers that monitor network traffic flows between the CDE and out-of-scope networks.
Answer: C
Explanation:
True segmentation, as defined inPCI DSS Scope Guidance, requiresenforcing isolationsuch thatno network traffic is allowed between the CDE and out-of-scope systems, unless explicitly permitted and secured. This is the only way toreduce assessment scopereliably.
* Option A:#Incorrect. Monitoring alone does not restrict or prevent access.
* Option B:#Incorrect. Logging without restriction doesnot isolatethe CDE.
* Option C:#Incorrect. VLANs may be part of segmentation, but routing traffic alone doesn't reduce scope.
* Option D:#Correct. This describesproper segmentation: no uncontrolled traffic into the CDE.

3.2.
NEW QUESTION # 43
An organization has implemented a change-detection mechanism on their systems. How often must critical file comparisons be performed?
- A. Periodically as defined by the entity
- B. Only after a valid change is installed
- C. At least weekly
- D. At least monthly
Answer: C
Explanation:
As specified underRequirement 11.5.2.1, comparisons of critical files (e.g., config files, executables) using change-detection mechanisms (e.g., FIM tools)must occur at least weekly. This ensures timely detection of unauthorized changes or tampering.
* Option A:#Correct. Weekly is theminimum frequencyrequired.
* Option B:#Incorrect. A defined "period" is not sufficient unless it's weekly or more frequent.
* Option C:#Incorrect. Scans should not wait for changes; they should detectunexpectedones.
* Option D:#Incorrect. Monthly is too infrequent for PCI DSS compliance.
Reference:PCI DSS v4.0.1 - Requirement 11.5.2.1.
NEW QUESTION # 44
An entity wants to use the Customized Approach. They are unsure how to complete the Controls Matrix or TRA. During the assessment, you spend time completing the Controls Matrix and the TRA, while also ensuring that the customized control is implemented securely. Which of the following statements is true?
- A. Assessors are not allowed to assist an entity with the completion of the Controls Matrix or the TRA.
- B. You can assess the customized control, but another assessor must verify thatyou completed the TRA correctly.
- C. You can assess the customized control and verify that the customized approach was correctly followed, but you must document this in the ROC.
- D. You must document the work on the customized control in the ROC, but you can not assess the control or the documentation.
Answer: C
Explanation:
Customized Approach Overview:
* Under PCI DSS v4.0, entities can use a Customized Approach to meet requirements by implementing controls tailored to their environment. This allows flexibility while still achieving the intent of the security requirement.
Role of Assessors:
* Assessors (QSAs) are responsible for evaluating both the implementation of customized controls and ensuring these controls fulfill the security objectives of the PCI DSS requirements.
* QSAs must document the evaluation, evidence reviewed, and results in the Report on Compliance (ROC).
Controls Matrix and Targeted Risk Analysis (TRA):
* The Controls Matrix and TRA are key components of the Customized Approach. QSAs assist in verifying the accuracy and completeness of these tools during assessments.
Documenting in the ROC:
* The ROC must include a narrative explaining the assessor's findings regarding the customized control, validation methods, and any evidence collected.
Relevant PCI DSS v4.0 Guidance:
* Appendix D and E of the PCI DSS v4.0 ROC Template emphasize that QSAs can evaluate and confirm adherence to the Customized Approach provided this is documented comprehensively in the ROC.

- A. Application IDs for database applications can only be used by database administrators.
- B. User access to the database is restricted to system and network administrators.
- C. Direct queries to the database are restricted to shared database administrator accounts.
- D. User access to the database is only through programmatic methods.
Answer: D
Explanation:
PerRequirement 7.2.5and8.2.2, PCI DSS recommends thatonly application-layer accessbe allowed to databases storing cardholder data, preventing users from issuing direct SQL queries or accessing the database via administrative tools.
* Option A:#Correct. Restricting database access toprogrammatic (application-layer) methodsis strongly preferred and aligns with PCI DSS guidance.
* Option B:#Incorrect. Admins should not have unrestricted access unless justified and monitored.
* Option C:#Incorrect. Application IDs must not be used interactively by individuals (Requirement 8.6.1).
* Option D:#Incorrect. Shared accounts are disallowed (Requirement 8.2.1).
NEW QUESTION # 46
Which statement about the Attestation of Compliance (AOC) is correct?
- A. There are different AOC templates for service providers and merchants.
- B. The AOC must be signed by both the merchant/service provider and by PCI SSC.
- C. The AOC must be signed by either the merchant/service provider or the QSA/ISA.
- D. The same AOC template is used for ROCs and SAQs.
Answer: A
Explanation:
There areseparate Attestation of Compliance (AOC) templatesfor different use cases, specifically formerchantsandservice providers, and forSAQsversusROCs. Each template is tailored to match the reporting needs of that assessment type.
* Option A:#Correct. PCI SSC publishes distinct AOC templates depending on whether the entity is a merchant or service provider, and depending on whether they are completing an SAQ or ROC.
* Option B:#Incorrect. The AOC is not signed by PCI SSC. It must be signed by the assessed entity and, where applicable, the QSA or ISA.
* Option C:#Incorrect. ROCs and SAQs use different AOC formats.
* Option D:#Incorrect. Both the entity and the assessor (if applicable)mustsign.
