ISTQB CT-PT Exam Syllabus Topics:

Topic	Details
Topic 1	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.
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	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	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.

NO.22 Which of the following is an advantage of using performance monitoring tools?

They can prevent malicious behavior.

They proactively compile metrics from server logs.

They more easily identify and report multi-threading problems.

They can proactively detect denial-of-service (DoS) attacks.

NO.23 What is the primary purpose of a load generator?

Create a steady and consistent background load on the system

Simulate user behavior in accordance with the defined operational profile

Record and analyze the behavior of the system as it is executing the prescribed tests

Support root cause analysis when performance degradation is encountered

NO.24 Which of the following is a static performance test?

Usability test of the user interface

Evaluation of the test execution skills of the testers

Review of the network architecture

Formal signature approval by the end users

NO.25 Which of the following is a typical performance risk associated with mainframe architectures?

Inconsistent loads when accessed via APIs

Slow hard disk speed

Misconfigured host machine

Lack of RAM

NO.26 How does a load management console aid performance testing?

It simulates user behavior.

It enables senior management to monitor testing.

It provides reports and graphs for analysis.

It emulates virtual users.

NO.27 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?

Preferably during each phase in the lifecycle

Preferably at the end of system testing

Preferably during system integration testing

Preferably at the end of unit testing

NO.28 At what point during performance testing does monitoring with the load testing tool begin?

When testing is concluded.

Before testing execution.

Immediately after test execution.

Simultaneously with test execution.

NO.29 Which of the following can provide measurements for both individual and aggregated elements within a single performance test?

Aggregated metrics

Process optimization tracking

Measuring underlying transactions

Nested transactions

NO.30 Which type of performance test measures the system’s ability to handle increasing levels of load?

Load testing

Elevation testing

Spike testing

Endurance testing

NO.31 During performance testing, in addition to the transaction response time, which of the following is needed to accurately reflect the total time to complete a transaction?

Think time

Wait time

Action time

User time

NO.32 Why is it important to specify how failures are handled during test execution?

To meet the expectations of the business stakeholders

To ensure that new failures are not introduced

To ensure all defects are captured

To minimize distractions during testing

NO.33 Which of the following performance script types measures network response times?

GUI scripts

API scripts

HTTP scripts

Protocol-level scripts

NO.34 You are managing the testing efforts of an existing distributed system that manages inventories of automobile and light truck tires from multiple warehouses across the country. The system is being enhanced to track incoming restocking shipments at the point of entry to the warehouse and outbound sales shipments at the point of shipment from the warehouse, all of which are executed in real-time. System loads traditionally peak on Mondays due to built-up demand from the previous weekend.
You are preparing a presentation to the business stakeholders, outlining your performance testing strategy.
Which of the following is appropriate to present to this audience?

A test plan that includes specific technical specifications for the computing hardware to be used for performance testing

The risks that may exist due to platform differences between the test environment and the production environment

A comprehensive list of support staff to be available during performance testing, including key members of the application development team

Established HTTP response per second goals that will have acceptable minimum, maximum, and average response times

NO.35 Which of the following should be a key part of your test acceptance criteria in your performance test plan?

Convincing technical and business stakeholders to provide realistic performance goals for the regional servers

Describing the system under test in order to provide context to the metrics

Highlighting any technical differences in the hardware between the test environment and the production environment

Documenting previously baselined performance metrics in order to compare these to the new performance measurements

NO.36 Which of the following is considered a characteristic of stress testing?

Considers the system’s ability to recover from a sudden increase of loads within the system’s limits.

It focuses on the system’s ability to handle transactions over a specific timeframe.

It determines the maximum number of transactions a system can handle.

It evaluates the system’s ability to handle loads beyond its design limits.

NO.37 Which of the following is a typical performance risk associated with distributed architectures?

A local hard disk that has been de-fragmented

Excess computer memory resources

Unreliable or unpredictable remote servers

Inconsistent Bluetooth connectivity

NO.38 What challenge must be considered when using crowds to emulate load generation?

The load generation will be difficult to reproduce.

The load generation method is less sensitive to changes in the III.

This type of load generation is more suitable for mainframe applications.

This technique is more precise than other methods of load generation.
