質問 1：
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.

質問 2：
(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.
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?
SELECT ONE OPTION
A. 11,700
B. 9,000
C. 23,400
D. 8,500

質問 3：
Scenario
James is participating in a project In which a web portal is being developed to sell tickets for different types of events.
Once the sale has been made and confirmed by the payment channel, the information must be available to the rest of the types of user (for example, the managers of each event) In a maximum time of 2 seconds (It Is expected that this temporal constraint will be met in 95% of the transactions and that 90% of the transactions will be completed at 100%).
Ticket sales take place during a time window (start date and time, end date and time) that is announced in advance. At the beginning of this window, there are peaks of 150 users per minute, for 5 minutes.
Question
Choose the option that enables James to meet the performance target.
SELECT ONE OPTION
A. Establish the acceptance criteria for response times.
B. Create a baseline corresponding to the total number of users registered in the production database.
C. Create a baseline for maximum attendance for the ticketing transaction.
D. There is no need to set a baseline for the peak attendance, it is a known value.
