What is the primary use of the GET method in REST?

• A. To create a new resource
• B. To replace an existing resource
• C. To request data from a specified resource
• D. To remove a specified resource

Answer: (C)

The GET method in REST is primarily used to request data from a specified resource. This aligns with the design principles of REST, which emphasize that GET requests should be idempotent, meaning multiple identical requests will have the same effect as a single request and do not change the state of the resource on the server. When a client sends a GET request to a server, it is essentially asking for data, like retrieving a specific resource or collection of resources without making any modifications to them. This behavior facilitates read operations, providing a way to interact with the existing data while keeping the server's resource state unchanged. The nature of GET requests is such that they might return representations of the requested resource, typically in formats like JSON or XML, which are easy to use in application development.
