ISTQB Certified Tester - Performance Testing 認定 CT-PT 試験問題 (Q16-Q21):
質問 # 16
Which of the following is a key challenge when testing applications in a cloud environment?
正解：D
解説：
One of the biggest challenges of cloud-based performance testing is the lack of control over test execution timing due to shared cloud resources. Cloud environments dynamically allocate computing power, meaning that test execution may vary due to background processes, VM migrations, or auto-scaling events.
Option B (Inability to generate load) is incorrect because cloud platforms can scale up resources to generate high loads.
Option C (Lack of behavior simulation tools) is incorrect because cloud providers offer robust testing tools.
Option D (Test execution speed being too high) is not a valid performance testing challenge.
質問 # 17
Why is it important to specify how failures are handled during test execution?
正解：D
解説：
During performance testing, it is crucial to define failure handling procedures to ensure that failures do not introduce additional errors into the test execution process. This helps maintain test accuracy and avoid misleading results.
Option A (Meeting stakeholder expectations) is important but not the primary reason for defining failure handling.
Option C (Capturing all defects) is a general testing principle, not specific to failure handling in performance tests.
Option D (Minimizing distractions) is not a valid reason for defining failure handling.
質問 # 18
Which type of performance test measures the system's ability to handle increasing levels of load?
正解：D
解説：
Load testing assesses a system's ability to handle gradually increasing levels of load and ensures that it meets performance expectations under normal and peak conditions.
Option B (Elevation testing) is incorrect because this term does not exist in ISTQB performance testing terminology.
Option C (Spike testing) focuses on sudden increases in load rather than gradual scaling.
Option D (Endurance testing) examines how a system performs over an extended period, rather than gradual load increases.
質問 # 19
Which of the following is usually identified by a performance test?
正解：C
解説：
Performance tests primarily identify resource bottlenecks such as CPU saturation, memory leaks, network congestion, and database slowdowns.
Option B (Suitability issues) is a functional requirement concern, not a performance issue.
Option C (Learnability concerns) relates to usability testing, not performance.
Option D (Accessibility requirements) falls under compliance and usability testing, not performance testing.
質問 # 20
What challenge must be considered when using crowds to emulate load generation?
正解：C
解説：
Crowd-based load generation relies on real users from different locations, making test conditions highly variable. This makes it difficult to reproduce the same test scenario multiple times under identical conditions.
Option B (Less sensitive to changes) is incorrect because crowd-based load is highly sensitive to external conditions (network, device types, etc.).
Option C (Suitable for mainframe applications) is incorrect because crowd-based load testing is typically used for web and cloud applications, not mainframes.
Option D (More precise than other methods) is incorrect because crowd-based load testing lacks precision due to real-world inconsistencies.
