Certified Cloud Security Professional (CCSP) — Question 482

The REST API is a widely used standard for communications of web-based services between clients and the servers hosting them.
Which protocol does the REST API depend on?

Answer options

• A. HTTP
• B. SSH
• C. SAML
• D. XML

Correct answer: A

Explanation

The correct answer is HTTP, as REST APIs are built on top of the HTTP protocol to enable communication over the web. SSH is a secure shell protocol used for secure remote logins, SAML is a standard for single sign-on, and XML is a markup language, none of which are directly related to the functioning of REST APIs.
