Câu 21: CT-PT: Certified Tester Performance Testing

You are managing the testing efforts of an existing distributed system that manages inventories of automobile and light truck tires from multiple warehouses across the country. The system is being enhanced to track incoming restocking shipments at the point of entry to the warehouse and outbound sales shipments at the point of shipment from the warehouse, all of which are executed in real-time. System loads traditionally peak on Mondays due to built-up demand from the previous weekend. The current production platform has been completely upgraded but is having performance problems with reporting that you didn't see during testing. You have done the analysis and determined that your test system has equivalent hardware, a significantly smaller database and you tested with the same number of virtual users as the number of real users in production. Which of the following could lead to this inconsistency?

1. A. Production hardware fatigue
2. B. There is a memory leak in production
3. C. There was data caching in the test environment but not in production
4. D. Not enough virtual users were used during testing so the simulation was not accurate — đáp án hiện tại
