   A team is automating tests for an API that uses a third-party geolocation service. The service has a monthly quota, and the team is concerned about exhausting it during test runs. What is the best way to manage this dependency?

   • AUse the real service for all tests to ensure accuracy.
   • BIncrease the quota by purchasing a higher plan.
   • CUse a stub that returns a fixed geolocation response for most tests, and reserve real API calls for a few critical tests.
   • DCache the geolocation responses in the test environment to avoid repeated calls.

   A team is automating tests for an API that depends on a notification service. The notification service sometimes returns a 500 error, but the API is designed to retry the call. The team wants to verify that the API's retry logic works correctly. What is the best way to test this?

   • AUse the real notification service and hope it fails during the test.
   • BMock the notification service to always return success.
   • CUse a stub that returns a 500 error on the first call and a success on the second call.
   • DIncrease the retry count in the API configuration to ensure success.

   A team is automating tests for an API that depends on a legacy system that is being decommissioned. The team has a limited time to run tests before the system is shut down. What is the most important consideration for the test automation strategy?

   • ADelay automation until the new system is in place.
   • BFocus on tests that validate the API's normal behavior with the legacy system.
   • CSpend time setting up service virtualization for the legacy system.
   • DPrioritize tests that validate the API's behavior when the legacy system is unavailable.

   A team is automating tests for a healthcare API that must comply with data privacy regulations. The API depends on a patient database that contains sensitive data. The team wants to use realistic data in tests but must avoid using production patient data. What is the best approach?

   • AMock the database entirely to avoid using any real data.
   • BUse production data but anonymize it before using it in tests.
   • CGenerate synthetic test data that mimics the structure and variety of production data.
   • DUse a small subset of production data with a signed agreement from the data owner.
