How are operations on REST APIs performed as compared to RPC APIs?

1. A. In a REST API, operations are performed on an object (node) that is identified by a URL, but RPC APIs are operation-oriented.
2. B. In a REST API, operations are performed on an external resource that is defined on the API, but the RCP APIs are resource-oriented.
3. C. In a REST API, operations are performed on a platform that is identified by the URL, but RPC APIs are platform-oriented.
4. D. In a REST API, operations are performed on an internal resource that is defined on the API, but RPC APIs are resource-oriented.

Correct Answer: D
In a REST API, operations are performed on resources, which are accessed and manipulated using HTTP verbs such as GET, POST, PUT, and DELETE. These resources are identified by a URL and are defined within the API. For example, an API may define a resource called "customers", which can be accessed using the URL "http://api.example.com/customers". To retrieve a list of customers, the client could make a GET request to this URL. To create a new customer, the client could make a POST request to the same URL with the necessary data in the request body. In contrast, in an RPC API, operations are performed by making function calls. The client makes a request to the server, specifying the function to be called and any necessary parameters. The server then executes the function and returns the result to the client. RPC APIs are operation-oriented, meaning that the focus is on the function being called rather than the resource being accessed.
