PCI ISA Exam Practice Questions & Answers
Domain: PCI DSS Fundamentals
Question 1
What is the primary goal of PCI DSS?
A. Increase payment processing speed
B. Protect cardholder data
C. Reduce merchant fees
D. Improve customer service
Answer: B
Rationale: PCI DSS was developed to protect cardholder data and reduce payment card fraud through
security controls.
Question 2
Which organization manages the PCI DSS standard?
A. ISO
B. NIST
C. PCI Security Standards Council
D. Visa
Answer: C
Rationale: The PCI Security Standards Council (PCI SSC) develops and maintains PCI DSS requirements.
Question 3
Cardholder data includes:
A. Full PAN only
B. PAN and cardholder name
C. PAN, expiration date, and service code when stored together
D. All of the above
,Answer: D
Rationale: PCI DSS defines cardholder data as PAN plus associated elements such as cardholder name,
expiration date, and service code.
Question 4
Sensitive Authentication Data (SAD) includes:
A. PAN
B. Cardholder name
C. CVV/CVC/CID
D. Expiration date
Answer: C
Rationale: CVV/CVC/CID values are classified as sensitive authentication data.
Question 5
After authorization, SAD may be stored if encrypted.
A. True
B. False
Answer: B
Rationale: PCI DSS prohibits storage of sensitive authentication data after authorization, even if
encrypted.
Question 6
Which PCI DSS requirement addresses firewalls and network security controls?
A. Requirement 1
B. Requirement 3
C. Requirement 8
D. Requirement 12
Answer: A
Rationale: Requirement 1 focuses on establishing and maintaining network security controls.
Question 7
The PAN must be rendered unreadable when stored.
,A. True
B. False
Answer: A
Rationale: Requirement 3 mandates protection of stored account data through encryption, truncation,
hashing, or tokenization.
Question 8
Which entity determines merchant compliance level?
A. PCI SSC
B. Acquiring Bank
C. Merchant
D. Internal Auditor
Answer: B
Rationale: Acquirers determine merchant validation requirements based on transaction volume and
risk.
Question 9
A compensating control may be used when:
A. A requirement is inconvenient
B. Budget is limited
C. Legitimate technical constraints exist
D. Management prefers alternatives
Answer: C
Rationale: Compensating controls are allowed only when technical or documented business constraints
prevent direct compliance.
Question 10
The Cardholder Data Environment (CDE) consists of:
A. Systems storing cardholder data only
B. Systems connected to cardholder data systems only
C. People, processes, and technologies storing, processing, or transmitting cardholder data
D. Payment terminals only
Answer: C
, Rationale: PCI DSS defines the CDE broadly to include all related systems, people, and processes.
Domain: Scope and Network Segmentation
Question 11
The purpose of network segmentation is to:
A. Eliminate PCI DSS compliance
B. Reduce PCI DSS scope
C. Replace encryption
D. Remove firewall requirements
Answer: B
Rationale: Effective segmentation reduces the number of systems in scope.
Question 12
Which technology is commonly used for segmentation?
A. VLANs and firewalls
B. Word processors
C. Spreadsheets
D. Printers
Answer: A
Rationale: Segmentation often relies on firewalls, ACLs, VLANs, and routing controls.
Question 13
A flat network generally:
A. Reduces scope
B. Increases scope
C. Eliminates risk
D. Improves compliance automatically
Answer: B
Rationale: Without segmentation, more systems become connected to the CDE and fall into scope.
Question 14
An assessor should verify segmentation through:
