   A team is testing a new online payment system. They have a test environment that is a scaled-down version of production, with half the CPU and memory. The team has run functional tests successfully, but performance tests show response times that are 3 times higher than expected. The business owner is concerned that the system will not meet performance targets in production. Which action is most appropriate?

   • AConclude that the system will fail performance targets in production and halt the release.
   • BRun the performance test again with more virtual users to see if the response times improve.
   • CImmediately escalate the issue to the development team to optimize the code.
   • DAnalyze the performance test results in the context of the scaled-down environment before concluding the system is too slow.

   A performance test team is preparing to validate a new e-commerce checkout service. They have a test script that sends HTTP requests, but they have not yet executed it against the running application. The team lead insists that the script must be run against the deployed build before any performance metrics can be reported. Which statement best explains why the team lead's requirement is correct?

   • ABecause the script must be compiled into a test harness before any metrics can be collected.
   • BBecause the application's source code must be instrumented with logging before any performance test can begin.
   • CBecause static analysis of the script can reveal performance bottlenecks without needing a running system.
   • DBecause dynamic testing requires executing the software to observe its actual behavior and collect measurements under load.

   A test team is working on a legacy system that has no automated test infrastructure. They need to validate a new feature that calculates shipping costs based on weight and destination. The team has a running instance of the application and a list of test cases. Which approach best applies dynamic testing in this context?

   • AReview the shipping cost calculation code to verify the logic is correct.
   • BManually execute the test cases through the application's user interface and record the calculated shipping costs.
   • CAsk the business analyst to confirm the shipping cost rules are correct.
   • DCreate a spreadsheet to calculate expected shipping costs and compare them to the code's logic.

   A performance test team is preparing to test a new online streaming service. The service is expected to have a baseline load of 1,000 concurrent users and a peak load of 5,000 concurrent users during major events. The team has a limited test window of 4 hours. They need to validate both functional correctness and performance under these loads. Which approach best balances the need for functional validation and performance measurement within the time constraint?

   • ARun the performance test at peak load first, then run the functional test suite at baseline load.
   • BRun a functional test suite at baseline load first, then run a performance test at peak load.
   • CRun only the performance test at peak load, as functional testing is not relevant to performance testing.
   • DRun the functional test suite and performance test simultaneously at peak load to save time.

   How is dynamic testing applied in performance testing?

   • ABy reviewing the performance requirements document for completeness
   • BBy analyzing the database schema for potential bottlenecks
   • CBy inspecting the load testing tool configuration
   • DBy executing the system under load to measure its behavior and performance metrics
