A. B. C. D. E.AB.
A stateless application is an application that does not store any data or information about the previous requests made by a user. Instead, each request made by the user contains all the necessary information to process the request, and the response sent back to the user is based solely on the information contained in the request. Here are the explanations for the true statements about stateless applications:
A. Different requests can be processed by different servers: This is true because each request contains all the necessary information to process it, and the server does not need to rely on any information stored about previous requests. As a result, requests can be distributed across multiple servers without any issues, making it easier to scale the application horizontally.
B. Requests are based only on information relayed with each request: This is also true because a stateless application does not store any information about previous requests. Each request is independent and contains all the necessary information to process it. This makes it easier to build distributed applications because requests can be handled by any server in the network.
C. Information about earlier requests must be kept and must be accessible: This statement is false because a stateless application does not store any information about previous requests. Each request is independent, and the server does not rely on any information from previous requests to process the current request.
D. The same server must be used to process all requests that are linked to the same state: This statement is false because a stateless application does not store any information about previous requests. Each request is independent, and the server does not rely on any information from previous requests to process the current request. Therefore, it does not matter which server processes the request, as long as the necessary information is contained in the request.
E. No state information can be shared across servers: This statement is true because a stateless application does not store any information about previous requests. Each request is independent, and the server does not rely on any information from previous requests to process the current request. Therefore, state information cannot be shared across servers because there is no state information to share.
