NEW QUESTION # 18
Your application relies on a backend database service. Using Istio, you want to configure a circuit breaker pattern to prevent cascading failures if the database becomes unresponsive. How would you implement this?

A. Utilize Istio's 'fault injection' feature to simulate failures and test the circuit breaker
B. Deploy a separate health check pod to monitor the database service and trigger the circuit breaker if needed
C. Use the 'timeout' setting in the Istio configuration to limit the duration of requests to the database
D. Create a custom Istio VirtualService with a 'destinationRule' specifying a fallback service in case of failure
E. Configure the 'retry' policy in the Istio configuration to automatically retry failed requests

Answer: D

Explanation:
Istio's VirtualService and DestinationRule features allow you to configure fallback services. In the case of the database being unavailable, you can define a fallback service or mechanism to handle the request. Option B helps test circuit breaker behavior but doesn't implement it. Option C could be used for retries, but doesn't address the circuit breaker pattern. Option D is related to request timeouts, not circuit breaking. Option E is a manual approach, while Istio provides a more integrated solution.
