PCI ISA Exam 2026/2027 Comprehensive Assessment
2026-2027 | Total Questions: 100 | 100% VERIFIED
Introduction
This comprehensive assessment measures the core knowledge required of candidates
preparing for the PCI ISA (Payment Card Industry Internal Security Assessor) examination.
The assessment spans six domains: PCI DSS Requirements and Security Procedures; ISA
Program Roles and Responsibilities; Payment Card Industry Security Standards; Network
Architecture and Security; Vulnerability Management; and Risk Assessment and Compliance
Operations. Each question tests a distinct sub-topic mapped to the official PCI ISA blueprint,
requiring applied control judgment, sound scoping decisions, and regulatory awareness
rather than simple recall. Mastery of this material demonstrates readiness for professional
certification and supports competent, defensible information systems security execution
across payment card environments.
Question 1. The PCI Security Standards Council was founded in 2006 by which five
payment brands?
A. Visa, PayPal, Stripe, Square, and Amex
B. Visa, Mastercard, SWIFT, SEPA, and Amex
C. Visa, UnionPay, Maestro, Cirrus, and Discover
D. Visa, Mastercard, American Express, Discover, and JCB
Correct Answer: D — Visa, Mastercard, American Express, Discover, and JCB
Rationale: The five founding card brands jointly established PCI SSC to manage security
standards. The other lists mix processors and networks that were not founders.
Question 2. The twelve PCI DSS top-level requirements are organized into:
A. Four tiers of escalating controls
B. Twelve independent silos with no common goals
C. Six goals covering secure networks, account data protection, vulnerability
management, access control, monitoring, and policy
D. Three phases of implementation
Correct Answer: C — Six goals covering secure networks, account data protection,
vulnerability management, access control, monitoring, and policy
Rationale: The standard groups 12 requirements under 6 security goals. Tiers, silos,
and phases misdescribe the structure.
Question 3. Storing sensitive authentication data such as full magnetic-stripe data, CVV2, or
PIN blocks after authorization is:
A. Permitted with strong encryption
B. Permitted for 90 days
C. Prohibited without exception under the standard
, D. Required for chargeback defense
Correct Answer: C — Prohibited without exception under the standard
Rationale: Sensitive authentication data may never be retained after authorization,
encrypted or not. Time limits and business justifications do not apply.
Question 4. When a PAN must be displayed on screen or printed, it may show at most:
A. The first 6 and last 4 digits, unless a documented business need justifies more
B. The last 8 digits only
C. All 16 digits if masked visually
D. Only the check digit
Correct Answer: A — The first 6 and last 4 digits, unless a documented business
need justifies more
Rationale: Display masking is limited to first six and last four without documented
need. The other allowances misstate the masking rule.
Question 5. Acceptable methods to render stored PAN unreadable include:
A. Base64 encoding
B. Renaming the database server
C. Storing the PAN in a separate unlabeled file
D. Truncation, tokenization, strong one-way hashes, and strong encryption
Correct Answer: D — Truncation, tokenization, strong one-way hashes, and strong
encryption
Rationale: Approved protections are irreversible or cryptographically strong. Encoding
is reversible, and relocation or renaming offers no protection.
Question 6. The split knowledge and dual control rules for cryptographic keys require that:
A. One administrator manages all keys for speed
B. Keys are emailed to vendors
C. No single person knows or holds complete clear-text key components, and two people
authorize key operations
D. Keys stay printed on labels near servers
Correct Answer: C — No single person knows or holds complete clear-text key
components, and two people authorize key operations
Rationale: Split knowledge divides key material; dual control requires multiple
authorizers. Sole administrators, email transfer, and labeled printouts violate key
custody rules.
Question 7. Changing vendor-supplied defaults and removing or disabling unnecessary
default accounts is required because:
A. Defaults are faster than new passwords
B. Default credentials are widely published and the first thing attackers try
C. Vendors forbid changes
, D. Defaults cannot be exploited
Correct Answer: B — Default credentials are widely published and the first thing
attackers try
Rationale: Well-known defaults make trivial entry points; the standard mandates
change. The other options invert security logic.
Question 8. Sensitive data traveling over open, public networks must be:
A. Encrypted with strong cryptography such as current TLS versions
B. Sent as plain text if SSL is available
C. Protected only by HTTPS on login pages
D. Compressed to hide contents
Correct Answer: A — Encrypted with strong cryptography such as current TLS
versions
Rationale: The standard requires strong, current encryption for public transmission.
Deprecated SSL, partial protection, and compression fail the requirement.
Question 9. Anti-malware mechanisms under the standard must:
A. Run only during business hours
B. Detect, alert on, and block malware, with signatures or mechanisms kept current
C. Be installed only on laptops
D. Be limited to email servers
Correct Answer: B — Detect, alert on, and block malware, with signatures or
mechanisms kept current
Rationale: Anti-malware must protect, detect, and stay updated on in-scope systems.
Time windows, device subsets, and server-only scope misstate coverage.
Question 10. High-risk patches for critical or high-severity vulnerabilities should be
installed:
A. Whenever the team finds spare time
B. Within one month of release, per the standard's patching timeframes
C. Only at annual refresh cycles
D. Never in production systems
Correct Answer: B — Within one month of release, per the standard's patching
timeframes
Rationale: Current requirements demand critical and high patches within one month.
Delay, annual cycles, and refusal contradict the timeframe.
Question 11. Access to the cardholder data environment must be restricted by:
A. Least privilege and business need-to-know, assigned by role
B. Universal access for convenience
C. Shared team logins
D. Rotating full-admin passwords among all staff
