What is the main purpose of spike testing?

To detect memory leaks over a long period

To assess the system's response to sudden, sharp increases in load

To find the system's breaking point under gradually increasing load

To verify system behavior under a steady, expected load

A company's web application is deployed on a fixed number of servers. Management wants to know two things: (1) the maximum load the current configuration can handle before failing, and (2) whether adding more servers would allow the system to handle even more load. The team can run only one test. Which test provides the most useful information for both questions?

Stress testing the current configuration to find its breaking point, then using that data to estimate the potential benefit of adding servers.

Volume testing with a large amount of data.

Scalability testing by adding servers and measuring the improvement.

Load testing at the expected peak load.

What is the primary goal of load testing?

To find the exact point at which the system crashes

To test the system with an extremely large database

To verify system behavior under expected load conditions

To verify the system can run for 24 hours without failure
