Câu 14: 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 rate of 25 transactions per hour from 1:00pm to 4:00pm daily and an average of 10 transactions for non-peak hours. How should the construction of this load profile appear?

3. C. Multiple graphs representing each server, illustrating peaks of 25 transactions per hour for a sustained for a 24-hour period
4. D. One graph representing an aggregate of all servers, illustrating a constant load of 15.6 transactions per hour sustained for an 8-hour period
