ISTQB Specialist (CT-PT) Mock Exam #4
A full-length ISTQB Certified Tester Performance Testing (CT-PT) mock exam: 40 questions, 90 minutes, 26 correct answers (65%) to pass. Every question carries one point, exactly as in the real exam, and the chapter split reproduces the official ISTQB Exam Structure Table to the question — 6 on basic concepts, 4 on performance measurement fundamentals, 7 on performance testing in the software lifecycle, 20 on performance testing tasks and 3 on tools — together with the cognitive-level budget of K1 2, K2 25, K3 4, K4 9. This paper is built around the decisions taken before a run starts and the limits of what a finished run can claim. Scenarios come from railway ticketing, hotel reservations bought as a service, video conferencing on a self-scaling cloud, container terminal operations, genome-analysis batches, e-discovery, pharmacy fulfilment, a vehicle-inspection register, payments reconciliation, property conveyancing, toll roads and a census campaign. The four K3 items are calculations: the steady-state window left inside a fixed maintenance slot, the allocation of virtual users across scripts from busy-hour volumes, the test data volume needed to represent a capacity-planning horizon, and the time a heap would take to reach its cap at the observed growth rate. The analysis items ask what the evidence supports rather than what the headline figure says: an aggregate that hides a failing payment script, a baseline comparison invalidated by a different data volume, an improvement indistinguishable from run-to-run variation, a growing queue behind a flat processing time, and the one component in the path that nobody instrumented. Every answer option, correct or not, carries its own rationale.

- K2 - Understand25 (63%)
- K3 - Apply4 (10%)
- K4 - Analyse9 (23%)
