Question 1

Base Scenario 2 : This Base Scenario 2 is used for 8 questions throughout this exam. When you refer to Base Scenario 2, you are referring to this description and only this description, without any modification.

Natalie works for a company that develops an online check-in management software for a major international airline.

Online check-in is available for passenger check-in from 24 to 1 hour before boarding time.

Once the registration is confirmed by the customer and the system, the information must be available to the rest of the types of users (flight managers, among others) in a maximum time of 3 seconds (it is expected that this temporal constraint is met in 90% of the transactions and that 90% of the transactions are completed at 100%).

At the beginning of the check-in window, there are peaks of 100 users per minute, for one minute.

Question

Which of the following options is a performance-related business objective that could be suitable for this project?

SELECT ONE OPTION

AThe system must be capable of supporting peak concurrent users in excess of 6,000 users per hour for one minute, accessing check-in without performance degradation, considering that peaks must not exceed a value that exceeds the processing capacity of the system.

BThe system must be able to support peak attendance of 1,000 users, considering that there cannot be more than two flights with overlapping schedules.

CThe system must be able to support 200 concurrent users with a response time of one second for the issuance of the boarding pass, considering that the fleet is likely to have a very high percentage of medium size aircraft.

DThe system must have a completion time of up to three seconds for 2,000 concurrent users for updating passenger check-in data

Answer : A

Given the scenario of online check-in with peak user activity, the most suitable performance-related business objective would be to ensure that the system can handle a high number of concurrent users within a short period without performance degradation. Option A directly addresses the requirement to support peak loads while maintaining system performance, which aligns with the specified peak of 100 users per minute.

Question 2

Which ONE of the following mechanisms is used to make the load test represent a load situation in a real production environment?

SELECT ONE OPTION

AGenerate load through the Application Programming Interface (API).

BConfigure environments with multiple points of presence.

CGenerate load through the User Interface.

DGradually restrict system resources during the load test.

Answer : C

Generating load through the User Interface (UI) is essential to replicate a real production environment accurately. This approach simulates real user interactions with the system, providing a more realistic assessment of how the system performs under actual usage conditions. According to ISTQB standards, using the UI to generate load helps identify performance issues that users might experience, ensuring that the test results are relevant and actionable.

Question 3

If a performance test is testing the response time of an application to be connected through remote access, which protocol is being used?

SELECT ONE OPTION

AMMS.

BRTE.

CWSCL.

DLDAP.

Answer : B

RTE (Remote Terminal Emulation) protocol is used when testing the response time of an application connected through remote access. It simulates interactions with applications over a network as if they were being accessed locally, making it suitable for remote access scenarios.

Question 4

Choose the MOST suitable description of the structure of a performance test script

SELECT ONE OPTION

AThe 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.

BThe clean-up section Is the section in which everything is prepared for the main part In order to comply with the preconditions, the main sections can be executed several times and the completion section is the section that takes care of recording the results In the corresponding repository.

CThe 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.

DThe 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

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.

Question 5

Which ONE of the following options represents a principle of performance testing?

SELECT ONE OPTION

AThe tests must be aligned with the defined expectations of different stakeholder groups, users In particular, system designers and operations staff

BThe tests can only be conducted, where resources allow, on complete systems and test environments that are representative of the production system.

CThe tests must be reproducible. Identical results must be obtained by repeating the tests on an unchanged system.

DThe tests must yield results that are both understandable and can be readily compared to the requirements desired by the technical team.

Answer : C

Reproducibility is a fundamental principle of performance testing, ensuring that identical results are obtained when tests are repeated on an unchanged system. This principle is critical for verifying the reliability and consistency of performance test outcomes, allowing testers to confidently identify and address performance issues. ISTQB standards emphasize reproducibility to ensure that performance testing provides accurate and actionable insights.

Question 6

Identify the activity that is NOT part of the performance test preparation.

SELECT ONE OPTION

ADeploying the environment.

BSetting up the system under test.

CSetting up the load generation and monitoring tools and making sure that all the necessary information will be collected.

DVirtualizing the servers.

Answer : D

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.

Question 7

(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).

* Natalie should make a presentation to the technical stakeholders In order to explain the performance test plan.

Question

Which ONE of the following options contains information that should be included in Natalie's presentation to the technical stakeholders?

SELECT ONE OPTION

AA spike test shall be conducted in a test environment equivalent to the production environment. Passengers shall be removed from the production environment, disassociated and Imported into the test environment.

BA spike test shall be conducted in the performance test environment set up by the systems manager. Preparation includes installation from the clone of the virtual machine identified for this purpose.

CThe cost of the spike test will be In line with the budget submitted by the cloud service provider. The test must take place within the planned timeframe and use the disassociation algorithm previously agreed.

DA performance test will be conducted to verify the management application s capability to support simultaneous, i.e. concurrent, request peaks. The objective is to check that the system will be able to support the operations.

Answer : B

When presenting to technical stakeholders, it is crucial to provide detailed information about the setup, preparation, and execution of the performance test.

* Option A talks about the test environment and passenger data logistics, which, while technical, is not as focused on the specific setup for the spike test.

* Option B details the specific environment setup by the systems manager and the preparation steps, which are highly relevant to technical stakeholders who will be involved in or overseeing the technical aspects of the test.

* Option C again focuses on budget and timeline, not technical details.

* Option D is more high-level about the purpose of the test, which is not as relevant for technical stakeholders who need the specifics of the test setup.

Thus, Option B is the best fit as it provides the necessary technical details for the spike test environment and preparation steps.
