Which two statements are true about REST? (Choose two.)

Question

Options

• AREST is a Protocol.
• BREST is Stateful.
• CREST is Reliable.
• DREST is Interoperable.
• EREST is Relative.

• A
  3% (1)
• C
  91% (30)
• E
  6% (2)

Explanation

REST (Representational State Transfer) is Reliable (C) because it operates over HTTP/HTTPS, which sits on top of TCP - a transport protocol that guarantees packet delivery and error detection. It is Interoperable (D) because it uses universal HTTP methods (GET, POST, PUT, DELETE) and standard data formats (JSON, XML) that any language, platform, or device can consume without special tooling.

Why the distractors are wrong:

• A (Protocol): REST is an architectural style or set of constraints, not a protocol - HTTP is the protocol REST typically runs on.
• B (Stateful): The opposite is true; statelessness is a core REST constraint - each request must carry all the information needed to process it.
• E (Relative): A nonsense distractor with no basis in REST principles.

Memory tip: REST Rests on Interoperability and Reliability (think RIR), but it is NOT a Protocol, NOT Stateful - remembering that "State" in REST stands for Representational State Transfer, not that it keeps state, helps lock in the statelessness principle.
