Scenario: In a load testing scenario for a banking application, you observe that the database response times degrade as the number of concurrent users increases. What could be the possible reason, and how would you address it?

The possible reason for degraded database response times could be poorly optimized database queries. Inefficient or poorly constructed queries can result in increased resource consumption and slower response times, especially under heavy loads. To address this issue, you would need to optimize the database queries by analyzing and restructuring them for better performance, ensuring appropriate indexing, and possibly rewriting inefficient queries. Additionally, monitoring and optimizing server resources and addressing network latency issues can further improve database performance.
