ISTQB Specialist (CT-PT) Probeprüfung #2

Full-length ISTQB Certified Tester Performance Testing practice exam: 40 questions, 90 minutes, pass mark 65% (26 of 40). The chapter split reproduces the official Exam Structure Table exactly — 6 / 4 / 7 / 20 / 3 — and so does the cognitive-level mix (K1 2, K2 25, K3 4, K4 9). Every question is worth one point, as in the real exam. This paper leans on bottleneck diagnosis: you read throughput, response-time, CPU, disk and connection-pool metrics and decide what the data actually says. Scenarios cover a hospital EHR, airline check-in and seat maps, telecom billing and top-ups, deadline-day tax e-filing, smart-meter telemetry ingestion, university course enrolment, a government permit portal and a warehouse management system with handheld scanners. Four calculation items ask you to derive think time from a target throughput, size a batch window, convert transactions per second into hits per second and network throughput, and locate the 90th percentile in a sorted sample. Every answer option — correct or not — comes with its own rationale.
