DVA-C02 · Question #587
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 correct answer is C. Configure the Redis client in the application to persist connections to the cluster by implementing. Implementing a connection pool in the Redis client reduces connection overhead and avoids frequent connection establishment, which helps to reduce latency and connection failures.
Question
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. Which solution will meet this requirement?
Options
- AConfigure the Redis client to use an exponential backoff retry strategy to establish cache
- BStore the scores in the application's memory. Perform bulk set operations on the scores that are
- CConfigure the Redis client in the application to persist connections to the cluster by implementing
- DDeploy more nodes in the ElastiCache cluster. Update the Redis client to discover the new
