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?

• A.Preferably at the end of system testing
• B.Preferably during system integration testing
• C.Preferably at the end of unit testing
• D.Preferably during each phase in the lifecycle

What is the primary purpose of a load generator?

• A.Record and analyze the behavior of the system as it is executing the prescribed tests
• B.Simulate user behavior in accordance with the defined operational profile
• C.Create a steady and consistent background load on the system
• D.Support root cause analysis when performance degradation is encountered

Which of the following is the most economical solution to minimize costs and time for performance testing for a high-end production client-server platform?

• A.Cloud-based environment
• B.No environment
• C.Mainframe environment
• D.Isolated lab environment

Which of the following is a typical performance risk associated with mobile, browser-based, and embedded real-time architectures?

• A.Misconfigured host machine
• B.Slow hard disk speed
• C.Unexpected loads due to API accessibility
• D.Internet connectivity issues

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?

• A.Based on the power purchaser information, create operational profiles for low and medium purchasers and use equal proportions of those profiles during the testing.
• B.Review and adjust the profile with key stakeholders prior to using it.
• C.Execute the performance test with the operational profile and adjust the parameters as needed.
• D.Aggregate the specific operational profiles into a single generic profile and use that generic profile for load testing.
