ISTQB CT-PT Exam Syllabus Topics:

TopicDetails
Topic 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.
Topic 2
  • 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 3
  • 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 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 (Q14-Q19):

NEW QUESTION # 14
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. Business stakeholders setting unrealistic performance goals
  • D. Differences in the hardware between the test and production environments

Answer: D

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 # 15
Which of the following is typically the result of oversaturation of system resources during performance testing?

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

Answer: D

Explanation:
When system resources (e.g., CPU, RAM, I/O) are oversaturated, the system becomes overloaded, leading to increased response times and poor application performance.
Option A (Gradual improvement of response time) is incorrect because performance degrades under heavy load.
Option C (Error logging decreases) is unlikely; in most cases, errors increase when systems reach their limits.
Option D (Database size decreases) is unrelated to performance saturation.


NEW QUESTION # 16
Which of the following is a general principle of performance testing?

  • A. Test results must vary when the tests are run repeatedly on an unchanged system.
  • B. Tests must align with the ideal outcome of stakeholders.
  • C. Tests must be executable within the project timeframe.
  • D. Test results must be comparable to tester expectations.

Answer: C

Explanation:
Performance testing is time-sensitive and must be designed to fit within the constraints of the project timeline. If performance tests take too long to execute, they may not be feasible within a given sprint or development cycle. The results should be reproducible, meaning the same test on an unchanged system should yield the same results (making option C incorrect). While stakeholder expectations are important, performance tests should be objective and based on defined benchmarks rather than subjective expectations (making option D incorrect).


NEW QUESTION # 17
What is an advantage of aggregating the results of performance testing?

  • A. Aggregated results provide more detail and allow for a more complete analysis of the test.
  • B. Aggregated results show when testing has been completed.
  • C. It is easier for stakeholders to draw a correct conclusion from aggregated results.
  • D. Testing is expedited when the results are aggregated.

Answer: C

Explanation:
Aggregating test results helps stakeholders understand performance trends by combining data points from multiple test runs. This makes it easier to draw conclusions about system behavior.
Option A is incorrect because aggregation may reduce detailed visibility, not increase it.
Option B is incorrect because aggregation does not expedite testing itself.
Option D is incorrect because aggregated results do not indicate test completion.


NEW QUESTION # 18
Which of the following is a typical performance risk associated with distributed architectures?

  • A. Inconsistent Bluetooth connectivity
  • B. Excess computer memory resources
  • C. Unreliable or unpredictable remote servers
  • D. A local hard disk that has been de-fragmented

Answer: C

Explanation:
A key risk in distributed systems is unreliable remote servers, which can lead to latency, timeouts, and failures in performance testing.
Option A (Hard disk de-fragmentation) is not a significant risk in distributed systems.
Option B (Excess memory) is a positive factor, not a risk.
Option D (Bluetooth connectivity) is unrelated to distributed system performance.
