PCI ISA Certification Exam 2026 120 Questions – PCI DSS Requirements, CDE, Security Controls, Compliance Guide | Payment Card Industry

This document contains approximately 120 exam-style questions with verified answers for the PCI ISA (Internal Security Assessor) certification exam. It covers essential PCI DSS topics including cardholder data protection, sensitive authentication data (SAD), PCI DSS requirements (1–12), compliance processes, and security controls, as presented across pages 1–9 of the document. The material provides a comprehensive and in-depth review of Payment Card Industry Data Security Standard (PCI DSS) concepts. It begins with foundational definitions such as cardholder data (PAN, cardholder name, expiration date) and sensitive authentication data (full track data, CVV, PINs), as outlined on page 1. It also explains key entities within the payment ecosystem, including merchants, acquirers, issuers, payment brands, and third-party service providers (TPSPs), clarifying their roles in processing and securing cardholder data (page 2). Additionally, the guide delivers detailed coverage of all 12 PCI DSS requirements, including network security controls, secure system configurations, data protection through encryption, access control, monitoring, and security testing (pages 2–3). It also explores compliance documentation such as ROC (Report on Compliance), SAQ (Self-Assessment Questionnaire), and AOC (Attestation of Compliance), along with the full PCI DSS assessment lifecycle—scope, assess, report, attest, and submit (pages 4–5). Further, the document includes critical operational and technical standards such as network segmentation, cardholder data environment (CDE) scope, truncation methods for PAN protection, and sampling techniques. It also provides key compliance timelines and requirements, including password policies (minimum 12 characters, change every 90 days), account lockout thresholds, audit log retention (12 months with 3 months immediately available), and vulnerability scanning and penetration testing frequencies (every 3–12 months depending on type), as detailed on pages 6–9. The structured Q&A format mirrors real PCI ISA exam scenarios, reinforcing both conceptual understanding and practical application of compliance standards. The content aligns closely with official PCI SSC documentation and training materials used in cybersecurity, compliance, and risk management programs.
