Question #1
What is the benefit of transaction nesting for performance testing?
- A . The possibility to measure the evolution of response time with the load.
- B . The ability to measure individual and aggregate activities.
- C . The possibility to measure the time elapsed for the transaction.
- D . The ability to measure reflection time to better represent when a real user performs an action.
Correct Answer: B
B
Explanation:
Transaction nesting allows performance testers to measure both individual activities within a transaction and the aggregate performance of the entire transaction. This is beneficial because it helps identify specific areas where performance issues may be occurring. By understanding both the granular and overall performance, testers can better pinpoint bottlenecks and optimize the system. This aligns with the ISTQB principles of comprehensive performance measurement and analysis to ensure system reliability and efficiency.

Question #7
Inadequate database design.
- A . True options: I, III, IV.
- B . True options: II, III, IV.
- C . True options: II, III, V.
- D . True options: I, II, IV.
Correct Answer: A
A
Explanation:
• 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.

Question #8
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.
- A . Establish the acceptance criteria for response times.
- B . Create a baseline corresponding to the total number of users registered in the production database.
- C . There is no need to set a baseline for the peak attendance, it is a known value.
- D . Create a baseline for maximum attendance for the ticketing transaction.
Correct Answer: D
D
Explanation:
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.

- A . True statements: II, IV.
- B . True statements: 111, V.
- C . True statements: III, IV.
- D . True statements: I, IV.
Correct Answer: C
C
Explanation:
Performance test scripts require meticulous verification and error handling to ensure they function as intended.
• Statement III: Manual intervention may be required to carry out remedial action in the event of an error. This is true as certain errors might require human judgment to resolve.
• Statement IV: Performance scripts should be subject to quality control and testing, just like any software product. This ensures the reliability and effectiveness of the performance test scripts. Statements I, II, and V have inaccuracies:
• Statement I: Verification using indirect methods can be necessary.
• Statement II: While logical rules are important, they are not always mandatory.
• Statement V: Default error handling may not be sufficient, and additional checks can be crucial.

Question #41
Select the architecture that, in addition to the virtualized systems, could present performance risks
associated with virtualization.
- A . Dynamic/cloud-based systems.
- B . Multi Tier systems.
- C . Client-server systems.
- D . Distributed systems.
Correct Answer: A
A
Explanation:
Dynamic and cloud-based systems introduce performance risks associated with virtualization due to the inherent nature of resource allocation and scalability in these environments. Virtualized systems often share physical resources, leading to potential contention and unpredictable performance impacts. These risks are more pronounced in dynamic/cloud-based architectures where resources are frequently allocated and deallocated based on demand, potentially causing latency, resource bottlenecks, and performance variability. ISTQB guidelines on performance testing emphasize understanding these risks to ensure reliable performance outcomes.
