Which protocol mirrors XML-RPC but uses JSON for data serialization?

• A. REST
• B. JSON-RPC
• C. XML-RPC
• D. SOAP

Answer: (B)

JSON-RPC follows the same remote procedure call idea as XML-RPC, where a client requests the execution of a named method with parameters and the server returns a result. The key distinction is the data format: JSON-RPC uses JSON to encode the request and response, instead of XML. This makes it lighter and easier to parse in modern web apps, especially those built around JavaScript and JSON. REST focuses on resources and standard HTTP verbs rather than invoking methods; SOAP uses a heavy XML-based envelope with extra features; XML-RPC uses XML for encoding RPC calls. So, the protocol that mirrors XML-RPC but uses JSON for data serialization is JSON-RPC.
