Identify the activity that is NOT part of the performance test preparation.
SELECT ONE OPTION
Virtualizing the servers is not typically part of performance test preparation. Performance test preparation generally involves activities such as deploying the test environment, setting up the system under test, and configuring load generation and monitoring tools to ensure accurate data collection. While virtualization can be an aspect of the overall infrastructure setup, it is not a direct step in preparing for performance testing. ISTQB performance testing guidelines emphasize setting up the environment, system, and tools specifically for performance test execution.
In which activity of the testing process are specific test conditions identified for performance testing?
SELECT ONE OPTION
In the testing process, specific test conditions for performance testing are identified during the Test Analysis phase. This phase involves reviewing and analyzing the test basis, such as requirements, architecture, and design, to identify the test conditions, which are the items or events of a component or system that could be verified by one or more test cases.

Associate each type of performance test (listed from 1 to 5) with part of a description that allows its characterization and/or identification (listed from A to E).
1. Endurance testing
2. Scalability testing
3. Capacity testing
4. Stress testing
5. Concurrency testing
1. Type of testing focused on the ability of a system to meet future efficiency requirements.
2. Type of testing used to evaluate a system's ability to handle reduced availability of resources.
3. Type of testing focused on the stability of the system over a specific time frame.
4. Type of testing used to determine the number of transactions a given system will support while still meeting established performance objectives.
5. Type of testing focused on the impact of situations where specific actions occur simultaneously.
SELECT ONE OPTION
The correct associations are based on the definitions of each type of performance testing:
1. Endurance testing: Focused on the stability of the system over a specific time frame. (B)
2. Scalability testing: Focused on the ability of a system to meet future efficiency requirements. (E)
3. Capacity testing: Used to determine the number of transactions a given system will support while still meeting established performance objectives. (A)
4. Stress testing: Evaluates a system's ability to handle reduced availability of resources. (D)
5. Concurrency testing: Focused on the impact of situations where specific actions occur simultaneously. (C)

Choose the VALID description of the ramp-up concept.
SELECT ONE OPTION
Ramp-up in performance testing refers to the phase where the number of virtual users is gradually increased to simulate the increase in load on the system. This is essential for determining how the system behaves under varying levels of stress. The correct description of the ramp-up concept aligns with option C, which involves increasing the number of concurrent users to simulate a transition from a steady state to a higher load scenario.

Select the option that identifies the possible causes of the degradation of a system's response over time during dynamic performance testing.
1. Disk fragmentation.
2. Network latency.
3. File repository growth.
4. Memory leaks.
5. Inadequate database design.
SELECT ONE OPTION
* Disk fragmentation (I) can lead to slower data retrieval times as the disk has to work harder to read fragmented files.
* File repository growth (III) increases the amount of data that must be managed and retrieved, which can slow down response times.
* Memory leaks (IV) gradually consume available memory, leading to slower system performance as the available memory for processing tasks decreases.
Network latency (II) and inadequate database design (V) are also potential causes of performance degradation, but in this context, options I, III, and IV are the most directly related to the gradual degradation of response times over time. This understanding is supported by common performance testing practices outlined in ISTQB materials.
