   How does a mock differ from service virtualization in terms of usage?

   • AMocks are typically used in unit tests to verify interactions between objects, while service virtualization is used in integration tests to simulate complete dependent systems.
   • BMocks are used to simulate network latency, while service virtualization is used to simulate application logic.
   • CMocks are created by testers, while service virtualization is created by developers.
   • DMocks are used only in manual testing, while service virtualization is used only in automated testing.

   A team is implementing service virtualization for the first time. They have limited experience and need to ensure the virtual services are maintained effectively. What is a key consideration for the team?

   • ACreate virtual services for all external dependencies, regardless of their stability.
   • BAssign ownership and establish a process for updating virtual services when the real services change.
   • CAvoid using service virtualization for legacy systems because they are too complex.
   • DUse service virtualization only for testing, not for development environments.

   A team is using service virtualization to simulate a payment gateway. They notice that the virtual service does not accurately simulate the timeout behavior of the real gateway. What is the most likely impact on testing?

   • ATests will be more reliable because the virtual service is more predictable.
   • BTests will fail because the virtual service does not match the real gateway's response format.
   • CTests will run faster because the virtual service is faster than the real gateway.
   • DTests may not cover error handling for timeouts, leading to undetected defects in the application.

   A team is using service virtualization to simulate a database service in their test environment. They notice that the virtual service does not accurately simulate the database's performance characteristics, such as slow queries. What is the most likely impact on testing?

   • APerformance issues in the application may not be detected until later stages.
   • BThe team will need to use the real database for all tests.
   • CFunctional tests will fail because the virtual service is too slow.
   • DThe virtual service will consume more resources than the real database.

   A team is using service virtualization to enable parallel development. The frontend team can start building against a virtual API while the backend team develops the real API. What is a potential risk of this approach?

   • AThe backend team will be forced to follow the virtual API's design.
   • BThe virtual API may not accurately reflect the real API's behavior, leading to integration issues later.
   • CThe frontend team will not be able to test error scenarios.
   • DThe virtual API will slow down the frontend team's development.
