[All Professional Cloud Developer Questions]

You are building an application that will store frequently accessed data in a Memorystore for Redis Cluster instance. You would like to make the application resilient to network issues. You need to ensure that the application handles client disconnections from a Redis instance gracefully to minimize disruption and ensure stability of the application. What should you do?

A. Immediately terminate the application instance upon detecting a Redis disconnection to force a restart, and wait for clients to reconnect to the cache as soon as the application becomes available.
B. Configure the Redis client to reconnect after a fixed delay of 60 seconds.
C. Use Memorystore’s automatic failover mechanisms to make the Redis cache available in a secondary zone.
D. Implement exponential backoff with a jitter when reconnecting after a disconnection. Configure client-side caching to serve data during brief outages.
