Certified Cloud Security Professional (CCSP) — Question 329

With an API, various features and optimizations are highly desirable to scalability, reliability, and security.
What does the REST API support that the SOAP API does NOT support?

Answer options

• A. Acceleration
• B. Caching
• C. Redundancy
• D. Encryption

Correct answer: B

Explanation

The correct answer is B, as REST APIs support caching mechanisms that enhance performance by storing responses for reuse. SOAP APIs, while secure and reliable, do not inherently offer caching features, which can limit efficiency. The other options, such as Acceleration, Redundancy, and Encryption, are not exclusive to REST APIs and can be implemented in both REST and SOAP contexts.
