   A company is accepting a new inventory management system. The business stakeholders have stated that the system should 'handle the expected number of users without slowing down.' The acceptance team needs to define a measurable performance efficiency requirement. Which requirement is most appropriate?

   • BThe system shall have a response time of less than 2 seconds for 99% of all requests, without specifying the load.
   • CThe system shall be fast enough for all users during normal business hours.
   • DThe system shall not slow down noticeably when many users are active.

   A retail company is preparing to accept a new e-commerce platform. The acceptance team has been given a requirement: 'The system must respond to product search requests quickly, even during peak shopping periods.' The team is unsure how to turn this into a measurable acceptance criterion. Which action best defines a testable performance efficiency requirement?

   • ARequire that the system's response time never exceeds 2 seconds under any circumstances, including during system maintenance.
   • BState that the system should be 'fast enough' and verify this by having a few team members manually test the search function during the acceptance period.
   • CSpecify a maximum response time of 2 seconds for 95% of search requests under a defined peak load of 500 concurrent users.
   • DSet a target of 2 seconds average response time for all search requests during a 24-hour period, regardless of load.

   During a performance acceptance test of a web application, the test team observes that response times are increasing steadily over the test duration. The test is still running, and the team needs to decide whether to continue or stop. What is the most appropriate action?

   • AIgnore the trend and continue, as performance tests are meant to run for a fixed duration.
   • BIncrease the load to see if the system recovers or fails faster.
   • CLet the test run to completion, as the acceptance criteria are based on the final average response time.
   • DStop the test and investigate the cause of the increasing response times before continuing.
