[NEW] ISTQB Certified Tester Performance Testing (CT-PT)

Performance Measurement Fundamentals (15%): Mastering metrics collection, result aggregation, and identifying key performance indicators (KPIs).

Performance Testing in the Software Lifecycle (30%): Evaluating risks across different architectures and aligning testing activities with development phases.

Performance Testing Tasks (30%): Defining objectives, creating load profiles, script implementation, and advanced result analysis.

Tools (10%): Selecting and evaluating tool suitability, understanding licensing, and integrating tools into CI/CD pipelines.

B. The load generator is not sending enough requests.

C. The network bandwidth has increased.

D. The think time in the script is set too high.

E. The database is performing an automatic backup.

F. The test environment is larger than the production environment.

Correct Answer: A

Explanation:

B (Incorrect): If the load generator wasn't sending enough requests, the response time wouldn't necessarily increase; it would stay low.

C (Incorrect): Increased bandwidth would generally improve or maintain performance, not cause a flat throughput with rising latency.

D (Incorrect): Higher think time reduces the frequency of requests, which would lead to lower throughput, not flat throughput with high latency.

E (Incorrect): While possible, it's a specific event rather than a general performance concept related to the relationship between load and throughput.

F (Incorrect): A larger environment would likely delay the bottleneck, not cause this specific flat-throughput/high-latency pattern.

Question 2: Which type of performance testing is specifically designed to determine if a system can sustain a defined load for a long period of time to identify potential memory leaks?

B. Stress Testing

C. Endurance (Soak) Testing

D. Scalability Testing

E. Component Testing

F. Static Testing

Correct Answer: C

Explanation:

A (Incorrect): Spike testing checks how the system handles sudden, massive increases in load.

B (Incorrect): Stress testing finds the breaking point of the system beyond its expected capacity.

D (Incorrect): Scalability testing determines the system's ability to grow with added resources.

E (Incorrect): Component testing focuses on individual modules, not system-wide endurance.

F (Incorrect): Static testing involves reviewing code or documentation without executing it.

Question 3: When selecting a performance testing tool, which factor is most critical for ensuring the tool can simulate realistic user behavior in a modern free build 8 python apps games and web application python master course?

B. Support for the specific communication protocols (e.g., HTTP/S, WebSockets).

C. The ability to run the tool on an old operating system.

D. Whether the tool logo is recognizable.

E. The number of pages in the user manual.

F. The tool's ability to spell-check the scripts.

Correct Answer: B

Explanation:

A, D, E, F (Incorrect): These are cosmetic or secondary factors that do not affect the functional ability to simulate load.

C (Incorrect): While compatibility matters, supporting modern protocols is more critical for "modern web applications" than legacy OS support.
