Free ISTQB Certified Tester – Performance Testing Exam CT-PT Exam Practice Test

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.

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

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

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.

Which of the following is a key reason to include ramp-up and ramp-down periods in a performance test?

• To ensure virtual users complete their transactions within a defined time window
• To simulate a more realistic user load pattern and avoid sudden system stress
• To provide a buffer for slow-performing transactions to complete
• To guarantee that all virtual users remain active throughout the test duration

Which type of performance test measures the system’s ability to handle increasing levels of load?

• Load testing
• Elevation testing
• Spike testing
• Endurance testing

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

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

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

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.

Which of the following is considered a common database protocol?

• ODBC
• JUNIT
• SMP
• MMS

Which of the following is a typical performance risk associated with mobile, browser-based, and embedded real-time architectures?

• Slow hard disk speed
• Misconfigured host machine
• Unexpected loads due to API accessibility
• Internet connectivity issues
