QSA_New_V4 Exam Dumps - PCI SSC PCI Qualified Professionals Questions and Answers

Formulti-tenant service providers,isolation and segmentationare critical. As perRequirement 12.10.3, each customer’s environment must besegregated and protectedsuch that no tenant can access another’s data or systems.

Option A:✅Correct. This is the foundational control —isolation of customer environments.

Option B:❌Incorrect. Exposing system config files is a security risk.

Option C:❌Incorrect. Shared user IDs areexplicitly prohibitedby Requirement 8.2.1.

Option D:❌Incorrect. Customers should only access their own logs.

PerSection 6 – Sampling for PCI DSS Assessments, the assessor must ensure the sample of business facilitiesincludes all types and locations, reflecting different operational environments. The goal is to cover variations that might affect compliance, such as data centers vs. call centers, or regional differences.

Option A:Incorrect. Each assessment may require a different sample depending on the environment.

Option B:Incorrect. There is no fixed 10% requirement for facility sampling.

Option C:Incorrect. A full review of every facility isn't required if representative sampling is used appropriately.

Option D:Correct. The samplingmust include all types and locationsof facilities to be valid.

PCI DSS allows for theuse of truncation and hashingfor protecting PAN, butRequirement 3.4.1and its guidance warn againstcombining hashed and truncated PANsin such a way that the original PAN could be reconstructed. If both formats exist,controls must ensurethey can't be used together to reverse-engineer the PAN.

Option A:✅Correct. Controls must ensure PAN cannot be reconstructed using both versions.

Option B:❌Incorrect. A hashed PAN does not need truncation — hashing is a separate mechanism.

Option C:❌Incorrect. PCI DSS aims to prevent correlation, not encourage it.

Option D:❌Incorrect. They can coexist, but must be secured so that PAN cannot be derived.

 Definition of Quarterly:

PCI DSS defines "quarterly" as occurring once within each calendar quarter. This means the activity must happen at least once in Q1, Q2, Q3, and Q4, with no rigid restrictions on specific days​​.

 Clarification on Other Options:

B:While 95–97 days approximates a quarter, it is not mandated as a rigid timeframe.

C/D:Fixed dates (e.g., 15th or 1st of specific months) are not prescribed in PCI DSS.

 Key Management Requirements:

PCI DSS Requirement 3.5 specifies the protection of cryptographic keys, including encryption, storage in secure cryptographic devices (SCDs), or as key components to ensure security and prevent unauthorized access​​.

 Clarifications on Cryptographic Key Protection:

A/B:Public keys and key strength requirements are not specified in this context.

D:Separation of duties mandates that key-encrypting and data-encrypting keys must not be assigned to the same custodian.

 Testing and Validation:

QSAs verify compliance by examining key management practices, storage mechanisms, and access controls for cryptographic keys during the assessment​.

According toRequirement 12.10.1, an effectiveincident response plan (IRP)must include steps to detect, respond to, and contain incidents such asunauthorised wireless access points. PCI DSS11.2.1also mandates quarterly rogue AP detection.

Option A:❌Incorrect. Notification to PCI SSC is not required; notification goes toacquirers/payment brands.

Option B:✅Correct. The IRP must includeresponse to unauthorised wireless access detection.

Option C:❌Incorrect. Records must beretained, not deleted.

Option D:❌Incorrect. Retaliatory or offensive actions arenot allowed or recommended.

TheSecure Software Lifecycle (SLC) Standardis part of PCI’sSoftware Security Framework (SSF). If an entity's software is developed under aPCI-recognised Secure SLC process, it maysatisfy parts of Requirement 6, especially around secure coding practices and vulnerability management.

Option A:❌Incorrect. SLC compliance alone doesn’t grant full PCI DSS compliance.

Option B:✅Correct. Secure SLC can help meetmany of the development-related controls.

Option C:❌Incorrect. There isimpact— potentially reducing scope/testing.

Option D:❌Incorrect. The software remainsin scope, but fewer controls may need to be separately validated.

PCI DSSRequirement 12.1.1requires that security policies and procedures be disseminated to all relevant personnel and that those individualsunderstand and acknowledgethe policies. While review and update frequencies are also part of compliance, the most complete and correct answer is that policies must be shared with affected parties.

Option A:Incorrect. Encryption is not specifically required for policy documents.

Option B:Incorrect. Limiting access to only management contradicts the requirement for distribution.

Option C:Incorrect. The correct review cycle per Requirement 12.1.2 isannually, not quarterly.

Option D:Correct. Policies and procedures must be understood and acknowledged by all affected parties.

TheROC Reporting Templaterequires assessors todocument how the requirement was verifiedas “In Place”. This includesmethods used, evidence reviewed, and how compliance was determined.

Option A:❌Incorrect. Project plans are relevant for “In Progress”, not “In Place”.

Option B:✅Correct. “In Place” requires an explanation ofassessor observations and validation.

Option C:❌Incorrect. This applies to “Not in Place”.

Option D:❌Incorrect. This applies to non-compliance scenarios.

 PCI DSS Reporting Expectations:

When documenting that a requirement is "In Place," the ROC must clearly describe how compliance was validated by the assessor. This involves detailing the evidence observed, such as system configurations, documentation, and personnel interviews​.

 ROC Documentation Guidelines:

The ROC Reporting Template specifies that each "In Place" response must include evidence demonstrating compliance with the requirement, such as testing observations and validation of implemented controls​.

 Eliminating Incorrect Options:

A:Project plans are not sufficient to demonstrate current compliance.

C/D:Responses discussing non-implementation or non-compliance are irrelevant when the requirement is "In Place."

 PCI DSS v4.0 ROC Template Guidance:

Appendix sections in the ROC provide specific instructions for assessors to document the testing performed, evidence reviewed, and results​.
