   In a regression test, the throughput at a given load is 800 requests per second, while the baseline recorded 1000 requests per second. What does this comparison indicate?

   • AA performance regression
   • BNo change in performance
   • CA performance improvement
   • DThe test load was too high

   A load test is run for a new online payment system. The results show that the average response time is 1 second, which is within the objective. However, the response time graph shows periodic spikes to 10 seconds every few minutes. What is the most likely cause of these spikes?

   • AThe load generator is sending requests in bursts.
   • BThe application is meeting its objective, so the spikes are not a concern.
   • CThe network is experiencing intermittent congestion.
   • DA scheduled batch job is competing for resources.

   A team is comparing a new test to a baseline. The baseline showed a throughput of 500 requests per second. The new test shows a throughput of 450 requests per second. The test environment, script, and data are identical. What is the most likely conclusion?

   • AThe application has regressed, showing a 10% decrease in throughput.
   • BThe results are within the acceptable margin of error and show no change.
   • CThe baseline is not reliable because it was from a previous test.
   • DThe application has improved, but the test was run incorrectly.

   During a load test of a web application, the test engineer observes that CPU utilization on the application server reaches 95% and remains there, while the response time curve shows a sharp, hockey-stick increase at the same moment. The database server CPU is at 20%. What is the most likely bottleneck?

   • AThe network bandwidth is saturated, causing the response time spike.
   • BThe load generator is the bottleneck, unable to generate more load.
   • CThe database server is the bottleneck due to low CPU usage.
   • DThe application server's CPU is saturated, limiting throughput.
