Question

Each web server process can invoke one or more __________ to handle the request.

Select one:
a. Database server processes
b. Application server processes
c. None of the others
d. Web server processes

Answer 1

A web server process can invoke application server processes to handle requests. Application servers run the logic and potentially interact with databases, returning the generated content to the web server.

Step-by-step explanation:

Each web server process can invoke one or more application server processes to handle the request. The correct answer is option b: Application server processes. When a web server receives a request, especially for dynamic content, it often forwards the request to an application server. The application server runs the necessary logic, interacts with databases if needed, and returns the generated content back to the web server which then delivers it to the client. This separation of concerns allows for greater scalability and the ability to specialize server roles to optimize performance.

Each web server process can invoke one or more Application server processes to handle the request. When a web server receives a request for a webpage, it can use an application server process to process and respond to the request. An application server is responsible for executing the application logic and retrieving data from databases if needed. It can handle multiple requests concurrently, making it efficient for handling multiple client requests.
