About CTFL-PT Exam
The CTFL-PT (ISTQB Certified Tester Foundation Level - Performance Testing) certification exam is a globally recognized qualification designed for software testing professionals who want to specialize in performance testing. This intermediate-level certification validates expertise in critical areas including performance testing fundamentals, test planning, test execution, and analysis of performance testing results. The exam covers essential topics such as load testing, stress testing, spike testing, and endurance testing, along with industry-standard tools and methodologies used in real-world scenarios. Professionals seeking this certification demonstrate their ability to identify performance bottlenecks, optimize system resources, and ensure applications meet quality standards under various load conditions.
The CTFL-PT exam is ideal for QA engineers, test automation specialists, and IT professionals looking to advance their careers in performance testing domains. Candidates preparing for this certification benefit significantly from using updated exam dumps and comprehensive practice tests that simulate the actual exam environment. High-quality study materials help learners master complex performance testing concepts, familiarize themselves with question formats, and build confidence before attempting the official exam. By leveraging practice tests and reliable study resources, candidates can identify knowledge gaps, improve their test-taking strategies, and increase their chances of achieving a passing score on their first attempt.

You have been asked to test the performance of a software and system update to a North American mobile trivia quiz game application. The quiz app is available on major app stores serving English-speaking users. The number of concurrent users planned for is 5 million. Winning quiz participants are promised a share of an allocated cash prize Once participants start playing, their quiz sessions must not be lost especially if all previous questions were answered correctly. The application owner wants to ensure that 99% of quiz sessions are maintained (up to 4 95 million sessions) until the last answer has been successfully recorded.
An essential operational profile you identified is the quiz participant. Your operational profile discovery efforts have yielded a number of profile attributes. A quiz participant will answer twelve questions if they manage to answer the first eleven correctly Every user is made aware of a new question nearly simultaneously. The quiz user has limited time to respond using a mobile application. They are unable to respond to subsequent questions after they incorrectly answer a question. However, the quiz participant continues to see new questions even though they may have responded incorrectly to a previous question If they manage to answer all twelve questions correctly, the quiz application notifies them that they have tentatively won (subject to formal verification) an equal share of a cash prize of an amount set for the particular quiz event In addition to this individualized interaction, a broadcast video stream is presented in the quiz app providing entertaining commentary quiz event coordination, event status and answer explanations.
The average quiz event duration when measured from when the first question is presented to the last answer is reviewed is fifteen minutes. Over the fifteen minutes, twelve questions are presented to quiz participants. After making the following assumptions:
1. Questions must be responded to within a four second window;
2. Question responses will be sent evenly across this window of time (resulting in an average responder time of two seconds);
3. The designed maximum number of concurrent users will attempt the first question;
4. There will be no functional issues when handling the load.
5. The average time from response reception to database commitment is 1000 milliseconds under maximum concurrent usage.
What is the approximate maximum average system throughput if that assumptions hold?
