What does it mean for an API endpoint to be IDEMPOTENT?
AThe endpoint can only be called once per IAM user, ever
BMaking the same request multiple times produces the same end state and side effects as making it once
CThe endpoint automatically rate-limits all callers to 1 request per second
DThe endpoint is encrypted with the strongest cipher available
Answer & Solution
Correct answer: B. Making the same request multiple times produces the same end state and side effects as making it once
Idempotency means N identical calls = same result as 1 call. Critical for retry-safe APIs and event-driven systems. The other options describe encryption, single-use endpoints, or rate-limiting — different properties.
