Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 991

Why are stateless calls executed by REST API useful in cloud applications?

Answer options

• A. They control URL decoding.
• B. They rely on data stored on the server for calls.
• C. They are easy to redeploy and to scale.
• D. They use HTTPS to implement all calls.

Correct answer: C

Explanation

The correct answer, C, highlights that stateless calls allow for easier redeployment and scaling because each request is independent and does not rely on previous interactions. Option A is incorrect as URL decoding is not specific to stateless calls. Option B is wrong because stateless interactions do not depend on stored data on the server. Option D is not a defining feature of stateless calls, even though HTTPS is used for secure communications.
