• B.Different stakeholders can see the speed at which a specific business process Is performed end-to-end.
• C.Performance trends can be identified
• D.Business and project stakeholders can see the overall status of system performance.

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

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

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).

2. Scalability testing
3. Capacity testing
4. Stress testing
5. Concurrency testing

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.

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.Create a baseline corresponding to the total number of users registered in the production database.
• B.There is no need to set a baseline for the peak attendance, it is a known value.
• C.Establish the acceptance criteria for response times.
• D.Create a baseline for maximum attendance for the ticketing transaction.
