1. What is the primary purpose of the Payment Card Industry Data Security
Standard (PCI DSS)?
A. To regulate merchant pricing for card transactions
B. To standardize software development practices globally
C. To provide a framework for auditing government financial systems
D. To reduce the risk of data breaches involving payment card data
E. To establish international banking regulations for credit issuers
✔ Correct Answer: D. To reduce the risk of data breaches involving payment card
data
EXPERT RATIONALE: PCI DSS was developed by the PCI Security Standards Council to
protect cardholder data and reduce payment card fraud by establishing security
controls for all entities that store, process, or transmit cardholder data.
2. Which organization is responsible for maintaining and publishing the PCI
DSS?
A. The Federal Reserve Board
B. The International Organization for Standardization (ISO)
,C. The PCI Security Standards Council (PCI SSC)
D. The National Institute of Standards and Technology (NIST)
E. The Financial Industry Regulatory Authority (FINRA)
✔ Correct Answer: C. The PCI Security Standards Council (PCI SSC)
EXPERT RATIONALE: The PCI SSC was founded in 2006 by American Express, Discover,
JCB, Mastercard, and Visa to manage and evolve the PCI DSS and related security
standards.
3. Which of the following entities is required to comply with PCI DSS?
A. Only banks that issue credit cards
B. Only e-commerce merchants with annual revenues over $1 million
C. Any entity that stores, processes, or transmits cardholder data
D. Only Level 1 merchants processing over 6 million transactions per year
E. Only third-party payment processors operating in the United States
✔ Correct Answer: C. Any entity that stores, processes, or transmits cardholder data
EXPERT RATIONALE: PCI DSS applies to all entities involved in payment card processing,
including merchants, processors, acquirers, issuers, and service providers — regardless
of size or transaction volume.
4. What does the term "cardholder data" (CHD) include under PCI DSS?
A. Only the 16-digit Primary Account Number (PAN)
B. The PAN plus cardholder name, expiration date, and service code
C. Only encrypted payment data stored in databases
D. Any financial transaction record stored by a merchant
E. Cardholder name and billing address only
,✔ Correct Answer: B. The PAN plus cardholder name, expiration date, and service
code
EXPERT RATIONALE: PCI DSS defines cardholder data as the PAN (minimum) plus any
combination of cardholder name, expiration date, and service code. The PAN is the
defining element — if it is present, PCI DSS protections apply.
5. Which of the following is classified as Sensitive Authentication Data (SAD)
under PCI DSS?
A. Cardholder name and billing address
B. Primary Account Number (PAN) stored in a database
C. Full magnetic stripe data, CVV2, and PINs
D. Expiration date and card network logo
E. Tokenized card numbers used in a vault
✔ Correct Answer: C. Full magnetic stripe data, CVV2, and PINs
EXPERT RATIONALE: Sensitive Authentication Data includes full track data from the
magnetic stripe or chip, CAV2/CVC2/CVV2/CID codes, and PINs/PIN blocks. SAD must
never be stored after authorization, even if encrypted.
6. After a transaction is authorized, which of the following is prohibited from
being stored under PCI DSS?
A. Truncated PAN
B. Cardholder name
C. Full magnetic stripe data
D. Transaction amount
E. Merchant reference number
✔ Correct Answer: C. Full magnetic stripe data
, EXPERT RATIONALE: PCI DSS Requirement 3.2 prohibits storage of Sensitive
Authentication Data after authorization, including full track data, CVV2, and PINs,
regardless of encryption status. This data is only needed for authorization and must not
be retained.
7. What is the minimum length for a strong password under PCI DSS
requirements?
A. 6 characters
B. 8 characters
C. 10 characters
D. 12 characters
E. 16 characters
✔ Correct Answer: B. 8 characters
EXPERT RATIONALE: PCI DSS requires passwords to be at least 8 characters long and
contain both numeric and alphabetic characters. Some versions have updated this
guidance, but 8 characters has been the baseline standard in core requirements.
8. How often must internal vulnerability scans be conducted under PCI DSS?
A. Annually
B. Every six months
C. Monthly
D. Quarterly
E. Only after significant changes to the network
✔ Correct Answer: D. Quarterly
