If Emily is conducting a performance test to determine that a system exposed to a load can respond to a high number of concurrent users during short periods of time that occur on specific days and at specific times, and then return to a stable state.
What type of performance testing is Emily conducting?
SELECT ONE OPTION
Spike testing involves subjecting a system to a significant increase in load for short periods of time to determine if it can handle sudden spikes in traffic. Emily's scenario of testing a system's response to a high number of concurrent users during specific periods and then returning to a stable state fits the description of spike testing.

ich ONE of the following options is a specific performance risk in mobile applications?
ONE OPTION
Mobile applications often face performance risks due to the limited resources available on mobile devices, such as CPU, memory, battery, and network bandwidth. These constraints can significantly impact the performance of mobile applications, leading to slower response times and degraded user experiences. ISTQB performance testing guidelines emphasize considering the specific resource limitations of mobile environments to ensure comprehensive performance evaluation and optimization.

Scenario
James is participating in a project In which a web portal is being developed to sell tickets for different types of events.
Once the sale has been made and confirmed by the payment channel, the information must be available to the rest of the types of user (for example, the managers of each event) In a maximum time of 2 seconds (It Is expected that this temporal constraint will be met in 95% of the transactions and that 90% of the transactions will be completed at 100%).
Ticket sales take place during a time window (start date and time, end date and time) that is announced in advance. At the beginning of this window, there are peaks of 150 users per minute, for 5 minutes.
Question
Choose the option that enables James to meet the performance target.
SELECT ONE OPTION
Creating a baseline for maximum attendance helps ensure that the system can handle peak loads. This baseline acts as a reference point for performance testing, allowing James to simulate and measure the system's behavior under expected peak conditions. By doing this, he can verify that the system meets the performance target of handling 150 users per minute within the specified time constraints. Establishing such baselines is a fundamental practice in performance testing, as emphasized by the ISTQB guidelines.
If George is testing in order to check the stability of a system for a specific period of time in an operational system context, what type of testing is MOST appropriate?
SELECT ONE OPTION
Endurance testing, also known as soak testing, evaluates the stability and performance of a system over an extended period under a significant load. This type of testing is designed to identify issues such as memory leaks, resource depletion, and other long-term stability problems that may not be evident in shorter testing durations. According to ISTQB guidelines, endurance testing is essential for ensuring that the system can maintain performance and stability over time, especially in operational contexts.
