Câu 15: 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. You have confirmed the test objectives with all stakeholders. In addition, you have constructed and verified an operational profile that emulates entities that submit large, bulk orders of 1600 tires or more per transaction. You have also verified and constructed this profile for peak processing at an average of rate of 25 transactions per hour with a processing time of 0.5 milliseconds per transaction. Assuming you are using 16 virtual users, which is the correct formula to calculate system throughput?

1. A. 1600 / 25 * 0.5 + [think time]
2. B. 16 / 0.05 + [think time]
3. C. 16 * 25 + [think time] — đáp án hiện tại
4. D. 0.5 * 25 - [think time]
