Q2 Single choice

A developer runs an application that displays scores for sports games on Amazon EC2 instances. The application uses a Redis client to retrieve the scores from an Amazon ElastiCache (Redis OSS) cluster.

The developer observes increased latency during operations on the cache because of connection failures to the cluster. The developer needs to resolve the latency issues.

A
Configure the Redis client to use an exponential backoff retry strategy to establish cache connections.
B
Store the scores in the application's memory. Perform bulk set operations on the scores that are stored in memory.
C
Configure the Redis client in the application to persist connections to the cluster by implementing a connection pool.
D
Deploy more nodes in the ElastiCache cluster. Update the Redis client to discover the new nodes.
