ISTQB CT-PT 시험요강:

주제
소개

주제 1

Types of Performance Testing: This section of the exam measures the skills of Software Test Analysts and covers various approaches such as load, stress, scalability, spike, endurance, concurrency, and capacity testing. It explains how each type evaluates system behavior under different conditions, helping testers and stakeholders understand how the system handles both expected and extreme usage scenarios.

주제 2

Testing Types in Performance Testing: This section of the exam introduces the distinction between static and dynamic performance testing. It shows how reviews of requirements, architecture, and code can identify risks before coding is complete, and how runtime checks of resource utilization and response times reveal issues that only appear when the system is in operation.

주제 3

Common Failures in Performance Testing and Their Causes: This section of the exam measures the skills of Performance Engineers and outlines frequent failure modes, including slow responses at various load levels, degraded performance over time, and system crashes under peak conditions. It provides examples of underlying causes such as resource leaks, insufficient capacity, and poor handling of spikes or concurrency, illustrating why robust planning and monitoring are crucial for reliable performance.

주제 4

The Concept of Load Generation: This section of the exam measures the skills of Software Test Analysts and discusses how representative loads are modeled and produced to simulate user or process behavior. It explores methods such as user interface inputs, crowdsourcing, API-based calls, or protocol capture and playback, emphasizing the need for repeatable loads that accurately reflect real-world conditions.

최신 Software Testing & Quality CT-PT 무료샘플문제 (Q34-Q39):

질문 # 34
Which of the following is a key challenge when testing applications in a cloud environment?

A. Limited ability to control test execution timing
B. Inability to generate significant load
C. Lack of user behavior simulation tools
D. Test execution speed being too high

정답：A

설명：
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.

질문 # 35
What is typically the result of oversaturation of system resources during performance testing?

A. Response time will be slow under significant load levels.
B. Response time will gradually improve over a period of time.
C. Error logging will decrease.
D. The size of the database will gradually decrease.

정답：A

설명：
When system resources are oversaturated (e.g., CPU, RAM, or network bandwidth), response times will degrade because the system struggles to process requests efficiently. This is a key performance bottleneck indicator.
Option A is incorrect because response times do not improve under heavy load; they typically worsen.
Option C is incorrect because error logging may actually increase rather than decrease under stress.
Option D is incorrect because database size is independent of system saturation unless records are actively purged.

질문 # 36
What is the primary purpose of a load generator?

A. Record and analyze the behavior of the system as it is executing the prescribed tests
B. Create a steady and consistent background load on the system
C. Simulate user behavior in accordance with the defined operational profile
D. Support root cause analysis when performance degradation is encountered

정답：C

설명：
A load generator is responsible for simulating virtual users and applying workloads to a system as defined by an operational profile. This allows testers to analyze how the system behaves under different load conditions.
Option A (Background load) is incorrect because load generators create simulated user interactions, not just background noise.
Option C (Record and analyze behavior) is the role of monitoring tools, not a load generator.
Option D (Support root cause analysis) is incorrect because root cause analysis is done after the load test, using monitoring tools.

질문 # 37
You are managing a project that is testing a system that manages a newly redesigned jet engine for heavy aircraft. Given the fact that this engine is specifically engineered to reduce noise, it is important that the software maintains enough thrust for lift for a period of 5 minutes without exceeding 87.5dB. The software must achieve this independent of other internal systems such as fuel or navigation management.
Given the risk for the ability of the aircraft to meet the noise abatement regulations while still being able to fly, when is the optimum time in the software lifecycle to apply the performance testing?

A. Preferably at the end of system testing
B. Preferably during system integration testing
C. Preferably at the end of unit testing
D. Preferably during each phase in the lifecycle

정답：D

설명：
Performance testing should be integrated into every phase of the software lifecycle to ensure that critical performance requirements (such as thrust-to-noise ratio) are met early and continuously validated.
Option B (End of system testing) is too late, as issues may be costly to fix at that stage.
Option C (During system integration testing) is useful but not comprehensive enough.
Option D (At the end of unit testing) is incorrect because unit tests do not assess overall system performance.

질문 # 38
You have run a load test. When examining the metrics, you see that the virtual users experienced many timeouts and excessive wait times. The system throughput metrics exceeded expected results, even during peak times.
Based on your analysis, what conclusion should you draw?

A. Virtual users are exhibiting impatient behavior.
B. New test data is needed.
C. Network infrastructure should be investigated.
D. Processing speed is too slow.

정답：D

설명：
If timeouts and excessive wait times occur, but throughput is high, this suggests that the system is unable to process requests fast enough. This points to slow processing speed due to CPU bottlenecks, memory limitations, or inefficient database queries.
Option A (Network infrastructure investigation) would be relevant if throughput was low or variable.
Option C (Impatient virtual users) is irrelevant; virtual users follow scripted behaviors.
Option D (New test data) does not address the core issue.
