A developer runs an application that displays scores for sports games on Amazon EC2 instances.

Why Option C is Correct:Implementing a connection pool in the Redis client reduces connection overhead and avoids frequent connection establishment, which helps to reduce latency and connection failures.

Why Other Options are Incorrect:

Option A:Exponential backoff retry strategies help with transient failures but do not resolve latency caused by frequent connection establishment.

Option B:Storing scores in application memory adds complexity and risks inconsistency.

Option D:Adding more nodes is unnecessary unless the cluster is under heavy load. Latency due to connection failures is better addressed at the application level.
