Select the architecture that, in addition to the virtualized systems, could present performance risks associated with virtualization.
SELECT ONE OPTION
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.
Which of following statements (listed I. to V.) are TRUE in characterizing result verification and error handling in a performance test script?
1. It is not necessary to verify that the script Is doing what It is supposed to do using Indirect methods, such as a database check.
2. The scripts should always include logical rules.
3. Manual intervention may be required to carry out remedial action in the event of an error.
4. Performance scripts should be subject to quality control and testing, just like any software product.
5. The default error handling of the performance test tools Is sufficient, so no additional checks need to be introduced.
SELECT ONE OPTION
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.

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

(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 business 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 business stakeholders?
SELECT ONE OPTION
When preparing a presentation for business stakeholders, it is essential to focus on high-level objectives and outcomes that align with business goals. In the context of performance testing, the stakeholders are primarily concerned with ensuring that the system can handle peak loads and maintain operational integrity.
* Option A talks about the setup of the test environment and the logistics of passenger data, which is too technical for business stakeholders.
* Option B focuses on budget and timeline, which are relevant but do not directly address the performance test's purpose and objectives.
* Option C clearly states the purpose of the performance test (spike test) and its objective, which is to verify that the system can support concurrent request peaks, directly aligning with business interests.
* Option D again focuses on technical details about the test environment setup, which is not the primary concern for business stakeholders.
Therefore, Option C is the most appropriate choice as it succinctly communicates the performance test's objective and its relevance to business operations.
