CCIE Data Center (legacy) — Question 37

Which three statements are characteristics of REST APIs? (Choose three.)

Answer options

• A. REST can use XML encoding
• B. REST uses HTML-style verbs
• C. REST APIs are stateful
• D. REST uses HTTP-style verbs
• E. REST requires JSON encoding
• F. REST APIs are stateless

Correct answer: A, C, D

Explanation

The correct answers highlight that REST can use XML for encoding, utilizes HTTP-style verbs for operations, and is stateless, meaning each request from the client to the server must contain all the information needed to understand and process the request. Options B, C, E, and F are incorrect as they either misrepresent the characteristics of REST or impose unnecessary restrictions.
