   A team is using service virtualization to simulate a third-party API. They have configured the virtual service to return a specific response for a given request. However, the team notices that the virtual service is not being used in some tests because the tests are directly calling the real API. What is the most likely cause?

   • AThe virtual service is not compatible with the test framework.
   • BThe tests are not configured to route requests to the virtual service.
   • CThe virtual service is not returning the correct response.
   • DThe virtual service is too slow to respond.

   A team is developing a new feature that depends on a partner API. The partner API is not yet available, but the team has a detailed specification. They want to test the integration early. What is the best approach?

   • AUse a mock object in the integration test code to simulate the API.
   • BWait until the partner API is available before testing the integration.
   • CUse a stub that returns a fixed response for all requests.
   • DCreate a service virtualization instance based on the specification to simulate the partner API.

   Which of the following is a key benefit of using service virtualization in agile development?

   • AIt reduces the need for unit testing because virtual services test the code automatically.
   • BIt allows testing to start earlier in the development cycle, even before dependent services are available.
   • CIt eliminates the need for any integration testing with real systems.
   • DIt guarantees that the production system will have zero defects.

   A team is using service virtualization to simulate a legacy system that is difficult to access. They have created a virtual service that mimics the legacy system's responses. However, the team is concerned that the virtual service may not accurately reflect the legacy system's behavior. What is the most effective way to address this concern?

   • APeriodically compare the virtual service's responses with the real legacy system's responses.
   • BAvoid using service virtualization for legacy systems because they are too complex.
   • CUse the real legacy system for all tests to avoid any inaccuracies.
   • DRely on the virtual service's specification to ensure accuracy.

   An agile team is working on a feature that depends on a third-party weather API. The API has rate limits and is only available during business hours. The team wants to run automated tests in the CI pipeline at any time. What is the primary benefit of using service virtualization in this situation?

   • AIt reduces the need for test data management because virtual services generate their own data.
   • BIt eliminates the need to test against the real third-party API entirely.
   • CIt allows tests to run without being constrained by the API's availability and rate limits.
   • DIt ensures the virtual service behaves exactly like the real API in all scenarios.
