Câu 25: 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. In a previous test, significant performance issues were seen when high volumes of outbound shipments were recorded to the database in near-concurrent time. This probably has been remedied by implementing a distributed database across multiple regional servers. You are now ready to run a new performance test with the distributed environment. What should be a key part of your test acceptance criteria in your performance test plan?

1. A. Convincing technical and business stakeholders to provide realistic performance goals for the regional servers
2. B. Describing the system under test in order to provide context to the metrics
3. C. Highlighting any technical differences in the hardware between the test environment and the production environment
4. D. Documenting previously baselined performance metrics in order to compare these to the new performance measurements — đáp án hiện tại
