A. Hardcode the credentials use Amazon S3 to host the web application, and enable server-side encryption
B. Run the web application in an Amazon EC2 instance with the instance profile configured
C. Configure Amazon Cognito identity pools and exchange the JSON Web Token (JWT) for temporary credentials

NEW QUESTION # 286
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 in the application to persist connections to the cluster by implementing a connection pool.
B. Configure the Redis client to use an exponential backoff retry strategy to establish cache connections.
C. Store the scores in the application's memory. Perform bulk set operations on the scores that are stored in memory.
D. Deploy more nodes in the ElastiCache cluster. Update the Redis client to discover the new nodes.

Answer: A

Explanation:
* 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.
* AWS Documentation References:
* Amazon ElastiCache Best Practices
