D . CONNECT

Answer: A, C

Explanation:

REST APIs use HTTP methods to perform different operations on resources. In the context of RPC (Remote Procedure Call) requests:

GET: This method is used to retrieve data from the server. In a REST API, it is commonly used to fetch information about resources, such as the current configuration or operational state.

POST: This method is used to send data to the server to create or update a resource. In the context of RPC, POST is often used to execute a procedure on the server that may result in the modification of a resource or triggering of an action.

Options B (HEAD) and D (CONNECT) are not typically used for executing RPC requests:

HEAD is similar to GET but only retrieves the headers, not the body of the response.

CONNECT is used to establish a tunnel to the server, primarily for SSL-encrypted communication, and is not commonly associated with RESTful RPC operations.
