   A stock trading platform experiences sudden, sharp increases in trading volume when major market events occur. The team has already verified that the platform can handle the expected peak load and remains stable over extended periods. Now, they want to verify that the platform can handle a sudden, sharp increase in trading volume without crashing. Which type of performance test should they run?

   • AStress testing, by continuously increasing volume until the system fails.
   • BSpike testing, by simulating a sudden, sharp increase in trading volume.
   • CLoad testing, by gradually increasing the trading volume to the expected peak.
   • DReliability testing, by running the platform at a sustained load for 24 hours.

   A team wants to determine if adding more servers to a system will allow it to handle more users without performance degradation. Which type of performance testing is most appropriate?

   • AStress testing
   • BSpike testing
   • CVolume testing
   • DScalability testing

   A mobile banking application has been stable under normal load. The operations team is concerned about two scenarios: (1) a sudden surge of users right after a major product launch, and (2) the possibility of a distributed denial-of-service (DDoS) attack that pushes traffic far beyond any expected level. The team has limited time and budget and can only run one performance test. Which test would provide the most useful information for both concerns?

   • ASpike testing, by suddenly increasing load to a high level and then returning to normal.
   • BStress testing, by gradually increasing load beyond expected levels until the system fails.
   • CLoad testing, by simulating the expected peak load during the product launch.
   • DEndurance testing, by running the system at a moderate load for 24 hours.

   An e-commerce platform must remain available and error-free during a 48-hour promotional period. The team has already verified that the system can handle the expected peak load and that it does not have memory leaks over extended periods. Now, they want to confirm that the system will remain stable and error-free for the entire 48-hour period under a realistic, sustained load. Which type of performance test should they run?

   • AScalability testing, by adding servers to see if performance improves.
   • BReliability testing, by running the system under a sustained, realistic load for the full 48-hour period and monitoring for errors and failures.
   • CStress testing, by pushing the system to its breaking point to see how it fails.
   • DSpike testing, by suddenly increasing the load to see if the system recovers.

   A retail company is preparing for its annual Black Friday sale. Historical data shows that traffic typically builds gradually over several hours, peaks at roughly 3x the normal load for about 90 minutes, and then declines. The team wants to verify that the checkout service remains responsive and does not return errors when the load reaches that 3x peak. Which performance testing approach should the team use?

   • ARun a load test that gradually ramps up to the expected 3x peak and sustains it for the expected duration.
   • BRun a spike test that instantly jumps from normal load to 3x load without a gradual ramp.
   • CRun an endurance test at 3x load for 24 hours to check for memory leaks.
   • DRun a stress test that immediately pushes the system to 5x the normal load to find the breaking point.
