Which is a valid description of REST?

Question

Options

• AREST provides the same architectural properties as SOAP.
• BREST is a library that is part of JEE called JAX-RS.
• CREST is the conventional way of interacting with information resources.
• DREST is a Web Services standard supported by JEE and JAX-RS.

• A
  6% (2)
• C
  3% (1)
• D
  91% (32)

Explanation

Option D is correct because REST (Representational State Transfer) is recognized as a web services architectural approach formally supported within the Java Enterprise Edition (JEE) ecosystem through the JAX-RS specification (Java API for RESTful Web Services), making it a legitimate standard for building web services in enterprise Java.

Why the distractors are wrong:

• A is incorrect because REST and SOAP have very different architectural properties - REST is stateless and resource-oriented (often using JSON), while SOAP is a strict XML-based protocol with its own envelope format.
• B confuses what REST is with how it's implemented - JAX-RS is the JEE API that enables REST, but REST itself is an architectural style, not a library.
• C is too vague and informal - while REST does involve interacting with resources, describing it as simply "the conventional way" ignores its definition as a standards-backed web services approach.

Memory tip: Remember the acronym - JAX-RS literally stands for Java API for RESTful Web Services, so whenever you see JAX-RS, think "this is JEE's way of implementing REST as a supported web services standard."
