ISTQB CT-PT Exam Syllabus Topics:

Topic
Details

Topic 1

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.

Topic 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.

Topic 3

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.

Topic 4

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.

ISTQB Certified Tester - Performance Testing Sample Questions (Q24-Q29):

NEW QUESTION # 24
Which of the following is a best practice to include in performance test scripts when verifying results?

A. Hold the development team accountable for system performance.
B. Verify that correct information was added to the database.
C. Add transaction timers to collect response times.
D. Increase the number of scripts executed to provide greater coverage.

Answer: B

NEW QUESTION # 25
At what point during performance testing does monitoring with the load testing tool begin?

A. When testing is concluded.
B. Simultaneously with test execution.
C. Before testing execution.
D. Immediately after test execution.

Answer: B

Explanation:
Performance monitoring must begin simultaneously with test execution to capture system behavior in real-time. This ensures that bottlenecks and performance issues are identified immediately.
Option A (After testing is concluded) is incorrect because historical monitoring does not help in real-time analysis.
Option B (Before execution) is incorrect because monitoring needs active system load to measure performance.
Option C (Immediately after execution) is incorrect because it misses runtime metrics.

NEW QUESTION # 26
Which of the following is a major contributor to unreliable performance projections?

A. Disagreement between the technical and business stakeholders during analysis
B. Redundancy between the test and production environments
C. Differences in the hardware between the test and production environments
D. Business stakeholders setting unrealistic performance goals

Answer: C

Explanation:
One of the biggest contributors to unreliable performance projections is differences between the test and production environments. If test environments do not match CPU, memory, network configurations, and database setups in production, the results may not be representative of real-world performance.
Option A (Redundancy between test and production environments) is not a problem; it's actually beneficial for reliability.
Option B (Disagreement between stakeholders) can affect planning but does not cause unreliable projections.
Option D (Unrealistic stakeholder goals) affects expectations but not the accuracy of projections.

NEW QUESTION # 27
What challenge must be considered when using crowds to emulate load generation?

A. This technique is more precise than other methods of load generation.
B. This type of load generation is more suitable for mainframe applications.
C. The load generation will be difficult to reproduce.
D. The load generation method is less sensitive to changes in the III.

Answer: C

Explanation:
Crowd-based load generation involves using distributed users (e.g., cloud-based testers or real users). The main challenge is that the load generation can be difficult to reproduce consistently due to variations in network conditions, device types, and user behavior.
Option B is incorrect because load generation methods should adapt to system changes.
Option C is incorrect since mainframe applications typically do not rely on crowd-based testing.
Option D is incorrect because crowd-sourced load testing is generally less precise than scripted load testing.

NEW QUESTION # 28
Which of the following could lead to inconsistent performance test results?

A. Sequential scripts running and attempting to access the same data.
B. Virtual users running the same script while logged in as the same user.
C. Expected results were not verified with senior management.
D. Concurrent scripts running and attempting to access the same data.

Answer: B

Explanation:
If multiple virtual users execute the same script while logged in as the same user, it can cause data conflicts, session collisions, or cache interference, leading to inconsistent performance test results.
Option A (Concurrent scripts accessing the same data) may cause data locking issues, but this is a test setup concern rather than an inconsistency issue.
Option B (Sequential scripts accessing the same data) does not typically cause inconsistencies since they execute in order.
Option D (Verification with management) is unrelated to technical inconsistencies.

NEW QUESTION # 29
