Refer to the exhibit. One of the backend systems invoked by an API implementation enforces rate limits on the number of requests a particular client can make. Both the backend system and the API implementation are deployed to several non-production environments in addition to production. Rate limiting of the backend system applies to all non-production environments. The production environment, however, does NOT have any rate limiting. What is the most effective approach to conduct performance tests of the API implementation in a staging (non-production) environment?

1. A. Use MUnit to simulate standard responses from the backend system Then conduct performance tests to identify other bottlenecks in the system
2. B. Create a mocking service that replicates the backend system's production performance characteristics Then configure the API implementation to use the mocking service and conduct the performance tests — đáp án hiện tại
3. C. Conduct scaled-down performance tests in the staging environment against the rate limited backend system Then upscale performance results to full production scale
4. D. Include logic within the API implementation that bypasses invocations of the backend system in a performance test situation, instead invoking local stubs that replicate typical backend system responses Then conduct performance tests using this API implementation
