NEW QUESTION # 18
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
- A. Create a baseline for maximum attendance for the ticketing transaction.
- B. There is no need to set a baseline for the peak attendance, it is a known value.
- C. Establish the acceptance criteria for response times.
- D. Create a baseline corresponding to the total number of users registered in the production database.
Answer: A
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.
NEW QUESTION # 19
Choose the option that BEST describes valid opportunities for the dynamic performance testing.
SELECT ONE OPTION
- A. During component Integration testing, across any kind of use cases and workflows, especially when integrating different use case features or Integrating with the "backbone" structure of a workflow.
- B. During system testing of overall end-to-end behaviors under various load conditions.
- C. During unit testing, including using or not profiling information to determine potential bottlenecks and white box techniques to evaluate resource utilization.
- D. During acceptance testing, especially for data flows and workflows across key inter-system interfaces. In system integration testing, it is not uncommon for the "user* to be another system or machine (e.g. inputs from sensor inputs and other systems).
Answer: B
Explanation:
System testing of overall end-to-end behaviors under various load conditions provides a comprehensive view of how the system performs in real-world scenarios. This type of testing captures interactions between components, identifies potential bottlenecks, and ensures that the system meets performance requirements under expected load conditions. ISTQB performance testing principles highlight the importance of end-to-end testing to validate that the system can handle the intended workloads effectively.
NEW QUESTION # 20
Given the following list of approaches to load generation, select the load generation approach that is LEAST reproducible and accurate.
SELECT ONE OPTION
- A. Load generation using crowds.
- B. Load generation via the Application Programming Interface (API).
- C. Load generation via the user interface.
- D. Load generation using captured communication protocols.
Answer: A
Explanation:
Load generation using crowds (crowdsourcing) is the least reproducible and accurate approach. This method involves using a large number of real users to generate load on the system. The variability in network conditions, user behavior, and device capabilities makes it difficult to reproduce the exact same load conditions consistently.

- B. The Initialization section Is the section in which everything Is prepared for the main part, the main sections are executed only once, because If It is necessary to repeat any action the whole script or part of it must be repeated and the clean-up section Is the section where the necessary steps are carried out to finish the test correctly.
- C. The initialization section Is the section in which everything Is prepared for the main part, the main sections can be executed several times and the finalization section is the section in charge of registering the results In the corresponding repository.
- D. The Initialization section is the section in which everything Is prepared for the main part, the main sections can be executed several times and the clean-up section is the section where the necessary steps are carried out to finish the test correctly.
Answer: D
Explanation:
A performance test script generally consists of three main sections:
* Initialization: This section sets up the preconditions and prepares the system for the main test actions. It ensures that the environment and the test are ready to execute.
* Main section: This is where the core test actions occur. These actions can be executed multiple times to simulate different loads and scenarios.
* Clean-up: This section includes steps to properly close the test, such as releasing resources, resetting states, and logging results.
This structure ensures that performance tests are conducted systematically and efficiently, as emphasized by ISTQB performance testing standards.

NEW QUESTION # 24
(REFER TO BASE SCENARIO 2): When you refer to Base Scenario 2, you are referring to the description and only the description, without any modification.
Question specific constraints: (specific constraints are not part of the Base Scenario and are specific to this question).
Throughout the month of January (31 days), the company performed 3,100 departure operations from the Capital City Airport. These departure operations transported 465,000 passengers during the hours of operation, from 07:00 to 23:00.
The departing passengers (one of the most relevant operational profiles) will access the front-end of the application to check in for their flight. It is known that 30% of departing passengers reconnect after checking in to request the boarding pass to be resent or printed.
Question
Assuming there is one boarding every 5 minutes, what should be the minimum front-end processing capacity of the system for the "departing passenger* user? It is assumed that there will be 12 peaks or maximums per hour.
SELECT ONE OPTION
- A. 100 * 12 + (60 -12) * (10.42 - 4.69) = 1.475.04 transactions/hour
- B. 100 * 12 + (60 -12) * 15.10 = 1,924.80 transactions/hour
- C. 100 * 12 + (60 -12) * 10.42 = 1.700.16 transactions/hour
- D. 100 * 12 + (60-12) *4.69 = 1,425.12 transactlons/hour
Answer: C
Explanation:
To calculate the minimum front-end processing capacity, we need to account for the peak and off-peak transactions:
1. Peak Transactions:
o Assume 12 peak periods per hour.
o During peak times, the transaction rate is 100 transactions/minute.
2. Off-Peak Transactions:
o There are 60 - 12 = 48 minutes of off-peak periods per hour.
o Off-peak transaction rate is 10.42 transactions/minute.
3. Total Transactions Per Hour:
o Peak transactions: 12 * 100 = 1,200 transactions.
o Off-peak transactions: 48 * 10.42 = 500.16 transactions.
o Total transactions per hour: 1,200 + 500.16 = 1,700.16 transactions/hour.
Thus, the correct answer is D. 100 * 12 + (60 - 12) * 10.42 = 1,700.16 transactions/hour.
