Final answer:
The tool that should be used to identify the maximum number of simultaneous sessions that a server can maintain before performance is negatively impacted is a load tester.
Step-by-step explanation:
The tool that should be used to identify the maximum number of simultaneous sessions that a server can maintain before performance is negatively impacted is a load tester. A load tester is a tool that simulates the behavior of multiple users accessing a website at the same time, allowing you to measure the response time and performance of the server under different loads.
With a load tester, you can simulate a large number of concurrent users accessing your website and monitor how the server handles the load. This will help you identify the maximum number of simultaneous sessions that the server can handle before performance begins to degrade.
By analyzing the data gathered from the load testing, you can optimize your server's configuration and scale your resources, such as increasing the server's capacity or implementing load balancing, to ensure that the website can handle the expected number of simultaneous sessions without negatively impacting performance.
