What is the put method within HTTP?

It replaces data at the destination.. The HTTP PUT method is used to update or replace a resource at a known URI. It is not a read-only operation; GET is read-only. It is generally treated as idempotent, meaning repeating the same PUT request should leave the resource in the same final state. It also does not simply display a web site. Cisco CCNA 200-301 v1.1 Automation and Programmability expects engineers to map REST operations to CRUD behavior: POST creates, GET reads, PUT updates or replaces, PATCH partially updates, and DELETE removes. The corrected answer is that PUT replaces data at the destination. That is the REST behavior being tested by this question.
