Discuss VMware 2V0-72.22 Exam Topic 9 Question 85

Which two options are REST principles? (Choose two.)

ARESTful applications use a stateless architecture.

BRESTful application use HTTP headers and status codes as a contract with the clients.

CRESTful applications cannot use caching.

DRESTful application servers keep track of the client state.

ERESTful applications favor tight coupling between the clients and the servers.

Suggested Answer: A, B

REST stands for Representational State Transfer, which is an architectural style for designing web services that adhere to certain principles. One of these principles is statelessness, which means that each request from a client to a server must contain all the information necessary to understand the request, and that no session state is maintained on the server side. Another principle is uniform interface, which means that clients and servers communicate using a standardized protocol, such as HTTP, and use its features, such as headers and status codes, to exchange information about the resources and their representations.
