What is the difference between static and dynamic web servers
A dynamic web server consists of a static web server plus extra software, most commonly an application server and a database.
It’s called "dynamic" because the application server updates the hosted files before sending them to your browser via the HTTP server.

Describe the 3 different methods you can follow to achieve the concurrent aproach
Multi-processing
In this a single process (parent process) initiates several single-threaded child processes and distribute incoming requests to these child processes. Each of the child processes are responsible for handling single request.
It is the responsibility of parent process to monitor the load and decide if processes should be killed or forked.
Multi-threaded
Unlike Multi-process, it creates multiple single-threaded process.
Hybrid
It is combination of above two approaches. In this approach multiple process are created and each process initiates multiple threads. Each of the threads handles one connection. Using multiple threads in single process results in less load on system resources.
