At ValidExamDumps, we consistently monitor updates to the iSQI CTFL-PT_D exam questions by iSQI. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the iSQI ISTQB Certified Tester Foundation Level - Specialist Performance Testing exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by iSQI in their iSQI CTFL-PT_D exam. These outdated questions lead to customers failing their iSQI ISTQB Certified Tester Foundation Level - Specialist Performance Testing exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the iSQI CTFL-PT_D exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.

* 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
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.
Identify the correspondences between the different tools (listed from 1 to 3) and their objectives and characteristics (listed from A to F).
1. Load generator.
2. Load management console.
3. Monitoring tool.
1. It monitors, records and/or analyzes the behavior of the component or system under test.
2. It creates the load and also collects the metrics for later communication.
3. It provides the control to start and stop the creation and execution of the user simulation.
4. It aggregates metrics from the various transactions that are defined within the load instances
5. It creates and runs multiple client instances that simulate user behavior.
6. It can effectively support a root cause analysis of performance in a system under test.
SELECT ONE OPTION
The correct associations between the tools and their objectives and characteristics are:
1. Load generator:
o 1B: It creates the load and also collects the metrics for later communication.
o 1E: It creates and runs multiple client instances that simulate user behavior.
2. Load management console:
o 2C: It provides the control to start and stop the creation and execution of the user simulation.
o 2D: It aggregates metrics from the various transactions that are defined within the load instances.
3. Monitoring tool:
o 3A: It monitors, records, and/or analyzes the behavior of the component or system under test.
o 3F: It can effectively support a root cause analysis of performance in a system under test.

Question specific constraints: (specific constraints are not part of the Base Scenario and are specific to this question).
* The project follows an iterative and Incremental development life cycle model.
* Development approach: Agile.
Question
Which of the statement(s) below is (are) TRUE regarding how the performance test is undertaken7
1. The performance test can have a dedicated iteration in a specific way.
2. Performance testing should be performed in a cloud-based performance test environment
3. The performance test may be conducted by a specific team.
4. A performance test cycle must be performed in each iteration by the development team (Agile).
SELECT ONE OPTION
In an Agile, iterative, and incremental development model:
* III: The performance test may be conducted by a specific team. This is true as dedicated performance testing teams often handle complex performance testing tasks.
* IV: A performance test cycle must be performed in each iteration by the development team (Agile). This ensures that performance testing is integrated into each iteration to catch performance issues early.
Statements I and II are not necessarily true:
* I: While possible, it is not always the case that there will be a dedicated iteration for performance testing.
* II: Performance testing in a cloud-based environment is beneficial but not mandatory.

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.

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
How many departing passengers access the front-end only once to check in per hour?
SELECT ONE OPTION
To calculate the number of departing passengers accessing the front-end only once to check in per hour, we follow these steps:
1. Total Departing Passengers in January:
o 465,000 passengers transported throughout January.
2. Duration of Operations in January:
o Operating hours: 07:00 to 23:00, which equals 16 hours per day.
o Total days in January: 31 days.
o Total operating hours in January: 31 days * 16 hours/day = 496 hours.
3. Passengers Per Hour:
o Total passengers: 465,000.
o Total hours of operation: 496 hours.
o Passengers per hour: 465,000 passengers / 496 hours = 937.5 passengers/hour.
4. Passengers Accessing Only Once for Check-In:
o 30% of departing passengers reconnect for a boarding pass, which means 70% access only once.
o Passengers accessing only once: 70% of 937.5 passengers/hour = 0.70 * 937.5 = 656.25 passengers/hour.
Given the available options, the closest correct value is C. 625.00 departing passengers / hour.
