問題文

A bank has separate environments for development, test and production. The same orders API has to carry a generous request limit in test so that load runs are not throttled, and a strict limit in production. A developer proposes one API instance whose limit is edited before each release. What should the architect recommend instead?

選択肢

1. One API instance per environment, each with its own policy configuration, so that the production limit is never edited to suit a load run in test and each environment keeps its own credentials and access rights
2. One API instance per consuming application, each with its own policy configuration, so that a load-testing application can be given a limit that production callers do not get
3. One API instance with two policy sets, one for test and one for production, so that the platform applies whichever set matches the caller's environment
4. One API instance per release branch, each with its own policy configuration, so that the production limit is never edited to suit a load run in test and each branch keeps its own credentials
