Exam 2V0-72.22 topic 1 question 3 discussion

The two options that are REST principles are: A. RESTful applications use a stateless architecture. This means that the server does not keep any client state between requests. Each request from the client to the server must contain all the information needed to understand and process the request. B. RESTful application use HTTP headers and status codes as a contract with the clients. HTTP headers and status codes are used to communicate the status of the request, any errors that occurred, and metadata about the returned resource. This is part of the uniform interface constraint of REST. Options C, D, and E are not principles of REST. RESTful applications can use caching (option C is incorrect), do not keep track of client state (option D is incorrect), and favor loose coupling between clients and servers (option E is incorrect).
