ISTQB CT-PT Practice Test - Questions Answers, Page 2

Which of the following is usually identified by a performance test?

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

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

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?

You are heading the testing effort for a system that manages the air/fuel ratio of direct-injection fuel devices built specifically for high-altitude rescue helicopter engines. At altitude, the system must be able to perform in order to make enough air/fuel ratio adjustments per millisecond between fuel and both an on-board source and available ambient air in order to prevent an engine stall due to oxygen starvation. The system is following a sequential development lifecycle.

For this safety-critical software, when is the appropriate point in the lifecycle to identify and define the performance goals?

Stakeholders were unhappy with previous performance test results, which indicated that the adjustments were not made fast enough and engine stall was probable. The developers have now made changes that they believe will significantly improve the performance of the adjustments.

What should you do to ensure the performance test objectives have been properly defined before you run the next set of performance tests?

Which of the following 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.

You are preparing a presentation to the business stakeholders, outlining your performance testing strategy.

Which of the following is appropriate to present to this audience?

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