Free ISTQB Certified Tester Foundation Level – Specialist Performance Testing Exam CTFL-PT_D Exam Practice Test

In which activity of the testing process is the scope of performance testing established? SELECT ONE OPTION

• Test analysis.
• Test design.
• Test planning.
• Test monitoring and control.

(REFER TO BASE SCENARIO 2): IV/rerj 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.QuestionA performance test will be carried out for which 11,700 transactions will be necessary to simulate an operation similar to that described in the base scenario and the restrictions of this question. How many virtual users will be necessary to achieve this number of transactions and the conditions of the operations?SELECT ONE OPTION

• 23,400
• 11,700
• 9,000
• 8,500

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

• Deploying the environment.
• Setting up the system under test.
• Setting up the load generation and monitoring tools and making sure that all the necessary information will be collected.
• Virtualizing the servers.

Select the ONE option that describes the mechanism used to extract metrics associated with deadlocks and multi threading problemsSELECT ONE OPTION

• Direct measurement from a dynamic performance test.
• Analysis and elaboration of metrics from a dynamic performance test.
• Direct measurement through a performance monitoring tool.
• Scan server logs and compile metrics from them.

What is the benefit of transaction nesting for performance testing? SELECT ONE OPTION

• The possibility to measure the evolution of response time with the load.
• The ability to measure individual and aggregate activities.
• The possibility to measure the time elapsed for the transaction.
• The ability to measure reflection time to better represent when a real user performs an action.

Choose the VALID description of the ramp-up concept. SELECT ONE OPTION

• Stage of reaching the stationary state.
• Stage of finishing the test.
• Stage of exit from a stationary state by increasing the number of concurrent users.
• Technique in which the load on the system is increased to a certain value in the shortest possible time.

ich ONE of the following options is a specific performance risk in mobile applications? ONE OPTION

• Network congestion.
• Slow data flow from sensors.
• Limited resources.
• Inefficient Implementation of algorithms.

In this question, consider that test scripts are generated from a protocol level recording. At the end of the recording, an attempt was made to execute the recorded scripts without any processing, and it was not possible to play them back.QuestionWhat could be the reason why it is not possible to play back the script? SELECT ONE OPTION

• The lack of business logic.
• The test script has not been correlated.
• The length of the script.
• The missing Initialization section.

SELECT ONE OPTION625.00 departing passengers / hour.1,425.00 departing passengers / hour1,700 00 departing passengers / hour.812.50 departing passengers / hour.

• 1,425.00 departing passengers / hour.

Choose the option that BEST describes valid opportunities for the dynamic performance testing. SELECT ONE OPTION

• 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.
• During system testing of overall end-to-end behaviors under various load conditions.
• 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).
• During unit testing, including using or not profiling information to determine potential bottlenecks and white box techniques to evaluate resource utilization.
