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	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	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 4	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.

NO.22 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.23 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 constructing an operational profile that emulates entities that submit large, bulk orders of greater than or equal to 1600 tires per transaction. You feel the profile you are constructing accurately reflects this type of power purchaser.
Which of the following steps must you take to ensure your operational profile is accurate?

Execute the performance test with the operational profile and adjust the parameters as needed.

Review and adjust the profile with key stakeholders prior to using it.

Aggregate the specific operational profiles into a single generic profile and use that generic profile for load testing.

Based on the power purchaser information, create operational profiles for low and medium purchasers and use equal proportions of those profiles during the testing.

NO.24 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.

NO.25 During which of the principal performance testing activities are the building blocks for larger, more complex tests created?

During test completion

During test planning

During test design

During test implementation

NO.26 What should be captured for batch processing performance metrics?

Throughput and wait times

Number of records deleted

Average percentage of network latency

Number of concurrent virtual users

NO.27 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 system under test.

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

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

NO.28 Which of the following performance script types measures network response times?

GUI scripts

API scripts

HTTP scripts

Protocol-level scripts

NO.29 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?

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

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

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

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

NO.30 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.31 Which of the following could lead to inconsistent performance test results?

Concurrent scripts running and attempting to access the same data.

Sequential scripts running and attempting to access the same data.

Virtual users running the same script while logged in as the same user.

Expected results were not verified with senior management.

NO.32 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.33 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.34 Stakeholders were unhappy with previous performance test results, which indicated that the adjustments were not made fast enough and engine stall was probable. The developers have now made changes that they believe will significantly improve the performance of the adjustments.
What should you do to ensure the performance test objectives have been properly defined before you run the next set of performance tests?

Understand the delta between the results from previous performance tests and the results from the expected performance improvements.

Adjust stakeholder expectations to be more aligned with the reality of the previous test results.

Realign performance test objectives with business stakeholders to meet project milestone dates.

Realign performance test objectives with all stakeholders to meet time-to-market goals.

NO.35 Which of the following is a best practice to include in performance test scripts when verifying results?

Increase the number of scripts executed to provide greater coverage.

Verify that correct information was added to the database.

Add transaction timers to collect response times.

Hold the development team accountable for system performance.

NO.36 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
