ISTQB Foundation (CTFL v4.0) Mock Exam #1

The first full-length CTFL v4.0 practice exam: 40 questions, 60 minutes, 65% to pass, weighted across all six chapters. Applied block: a decision table for checkout free shipping and a 5% discount, a PIN-entry state machine that locks the account on the third wrong attempt, and branch coverage on a control-flow graph containing a loop. Theory focus: root-cause analysis and defect clustering, review formality (inspection vs walkthrough), risk-based testing factors and test estimation. Every answer option carries a written rationale.
