(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).

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 per hour?

Question

A 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?

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.

Associate each type of performance test (listed from 1 to 5) with part of a description that allows its characterization and/or identification (listed from A to E).

1.Endurance testing

2.Scalability testing

3.Capacity testing

4.Stress testing

5.Concurrency testing

1.Type of testing focused on the ability of a system to meet future efficiency requirements.

2.Type of testing used to evaluate a system's ability to handle reduced availability of resources.

3.Type of testing focused on the stability of the system over a specific time frame.

4.Type of testing used to determine the number of transactions a given system will support while still meeting established performance objectives.

5.Type of testing focused on the impact of situations where specific actions occur simultaneously.

Base Scenario 1: This Base Scenario 1 is used for 2 questions throughout this exam. When you refer to Base Scenario 1, you are referring to this description and only this description, without any modification.

k given project for the development of a management software that will have a multilayer architecture will enable Its users to Install it in multiple locations, nationally and internationally - each installation can operate Independently and communicate with other instances in a selective way. Each installation shall have a high processing capacity.

Question

Assuming there is one boarding every 5 minutes, what should be the minimum front-end processing capacity of the system for the "departing passenger* user? It is assumed that there will be 12 peaks or maximums per hour.
