Correct answer & explanation
✓
PUT
GET and PUT are both idempotent. Idempotent methods produce the same result when called multiple times. GET is idempotent because it retrieves a resource without side effects. PUT is idempotent because multiple identical PUT requests result in the same resource state. POST is not idempotent because it creates new resources. PATCH is not idempotent because the same patch may have different effects on different resource states. DELETE is also idempotent, but the question specifically asks for two methods, and GET and PUT are universally recognized as idempotent.
