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.

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

• Generate load through the Application Programming Interface (API).
• Configure environments with multiple points of presence.
• Generate load through the User Interface.
• Gradually restrict system resources during the load test.

Choose the ONE option that describes the example of a transaction. The scenario for this question is the transfer of an amount of money from one bank account to another.SELECT ONE OPTION

• Request transfer of X Monetary Units from account K to account P; reduce the balance of account K by X Monetary Units; Increase the balance of account P by X Monetary Units. If the reduction and Increase have been correctly applied, then apply changes.
• Request transfer of X Monetary Units from account K to account P; increase the balance of account P by X Monetary Units. If the increase in account P has been correctly applied, then apply changes.
• Request transfer of X Monetary Units from account K to account P; decrease the balance of account K by X Monetary Units. If the reduction in account K has been correctly applied, then apply changes.
• Request transfer of X Monetary Units from account K to account P; reduce the balance of account K by X Monetary Units; increase the balance of account P by X Monetary Units. If the reduction or increase has been correctly applied, then apply changes

• 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.

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

• Limited resources.
• Inefficient Implementation of algorithms.

(REFER TO BASE SCENARIO 2): When you refer to Base Scenario 2. you are referring to thedescription 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.QuestionWhich ONE of the following options contains information that should be included in Natalie's presentation to the business stakeholders?SELECT ONE OPTION

• A 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.
• The cost of the spike test will be in line with the budget submitted by the cloud service provider. The test must take place in the planned timeframe and use the disassociation algorithm, that were previously agreed on.
• A performance test will be conducted to verify the management applications capability to support simultaneous, i.e concurrent, request peaks. The objective of this test (spike test) is to check that the system will be able to support the operations.
• A 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.

(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

Which of following statements (listed I. to V.) are TRUE in characterizing result verification and error handling in a performance test script?

• It is not necessary to verify that the script Is doing what It is supposed to do using Indirectmethods, such as a database check.
• The scripts should always include logical rules.
• Manual intervention may be required to carry out remedial action in the event of an error.
• Performance scripts should be subject to quality control and testing, just like any software product.
• The default error handling of the performance test tools Is sufficient, so no additional checks need to be introduced.SELECT ONE OPTION
• True statements: II, IV.
• True statements: 111, V.
• True statements: III, IV.
• True statements: I, IV.
