Which of the following is considered a characteristic of stress testing?

Which of the following performance script types measures network response times?

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 are constructing an operational profile that emulates entities that submit large, bulk orders of greater than or equal to 1600 tires per transaction. You feel the profile you are constructing accurately reflects this type of power purchaser.
Which of the following steps must you take to ensure your operational profile is accurate?

What is the primary purpose of a load generator?

Which of the following is a typical performance risk associated with mainframe architectures?

Which of the following is considered a common web service protocol?

You are managing a project that is testing a system that manages a newly redesigned jet engine for heavy aircraft. Given the fact that this engine is specifically engineered to reduce noise, it is important that the software maintains enough thrust for lift for a period of 5 minutes without exceeding 87.5dB. The software must achieve this independent of other internal systems such as fuel or navigation management.
Given the risk for the ability of the aircraft to meet the noise abatement regulations while still being able to fly, when is the optimum time in the software lifecycle to apply the performance testing?

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 are preparing a presentation for a group of technical stakeholders, outlining your performance testing strategy. Which of the following is appropriate to present to this audience?

Which of the following is an advantage of using performance monitoring tools?

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?

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?

What is typically the result of oversaturation of system resources during performance testing?

What should be captured for batch processing performance metrics?

During performance testing, in addition to the transaction response time, which of the following is needed to accurately reflect the total time to complete a transaction?

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.
Your performance test plan outlines running tests using multiple virtual users for better control of transaction times. However, you have analyzed the test data after execution and there are inconsistencies in the results.
Which of the following could lead to such results?

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.
However, western regions typically demonstrate more transactions on Tuesdays. You must be able to isolate excessive loads on servers based on region in order to ensure acceptable performance across the entire distributed server network.
With this in mind, what must you consider when selecting a performance testing tool?
