Which statement best characterizes REST in terms of complexity and transparency?

• A. REST is easier to understand and use because it leverages HTTP and CRUD.
• B. SOAP is always simpler.
• C. REST requires more complex contracts via WSDL.
• D. REST cannot be used with JSON.

Answer: (A)

REST’s simplicity comes from using the existing HTTP protocol and mapping actions directly to CRUD operations on resources. Because you perform standard HTTP methods (like GET, POST, PUT, DELETE) and address resources via URLs, the behavior is familiar, predictable, and easy to test with everyday web tools. This makes REST more transparent and approachable than other approaches that add extra layers or messaging formats. The other statements don’t fit because SOAP typically involves more boilerplate, envelopes, and contracts, which adds complexity. WSDL is a description tool tied to SOAP’s contract-style interfaces, not REST. And REST isn’t limited to JSON—while JSON is common, REST can work with XML or other representations as well.
