Which HTTP verbs are typically used for CRUD operations in REST?

• A. POST, GET, PUT, DELETE
• B. CONNECT, TRACE, MERGE, RENAME
• C. OPEN, CLOSE, SEND, RECEIVE
• D. GET, PULL, PUSH, SYNC

Answer: (A)

In REST, CRUD operations map to HTTP methods to reflect resource state changes: create uses POST, read uses GET, update uses PUT (and often PATCH for partial updates), and delete uses DELETE. POST creates a new resource on the server, GET retrieves a resource without changing it, PUT replaces the entire resource at a given URL (often used as an upsert in some designs), and DELETE removes the resource. This four-method pairing aligns with how REST handles resource lifecycles. The other options include methods that aren’t part of the standard CRUD pattern (like protocol/debugging methods or nonstandard actions), so they don’t fit the typical REST CRUD mapping.
