The method __________ is called to start asynchronous processing in a servlet.
- asynchronous()
- beginAsync()
- initAsync()
- startAsync()
The startAsync() method is called to initiate asynchronous processing in a servlet.
The __________ method of AsyncContext is used to dispatch the request to another servlet.
- dispatch()
- forward()

- sendRedirect()
The dispatch() method of AsyncContext is used to dispatch the request to another servlet during asynchronous processing.
What is the primary use of RequestDispatcher in servlets?
- Forwarding requests
- Initializing servlets
- Processing GET requests
- Sending redirect responses
The primary use of RequestDispatcher in servlets is for forwarding requests to another resource (servlet, JSP, or HTML) on the server.
What method is used to complete the asynchronous process and send a response?
- complete()
- finalize()
- finish()
- sendResponse()
The complete() method is used to complete the asynchronous process and send a response in asynchronous servlets.
How can a servlet determine if an incoming request supports asynchronous processing?
- canAsyncProcess()
- isAsyncRequest()
- isAsyncSupported()
- supportsAsync()
The isAsyncSupported() method is used by a servlet to determine if an incoming request supports asynchronous processing.
How does asynchronous processing in servlets improve server resource utilization?
- Increases server load
- Increases thread blocking
- No impact on thread blocking
- Reduces thread blocking
Asynchronous processing reduces thread blocking, allowing the server to handle more requests without waiting for each to complete, thus improving resource utilization.
Which HTTP status code is typically sent by an HTTP servlet to indicate a successful response?
- 200 OK
- 302 Found
- 404 Not Found
- 500 Internal Server Error
The HTTP status code 200 OK is typically sent by an HTTP servlet to indicate a successful response. This status code signals that the request has been successfully processed, and the server is returning the requested resource.
