  • Topic 1 Question 201

    A company has an application that stores data in Amazon RDS instances. The application periodically experiences surges of high traffic that cause performance problems. During periods of peak traffic, a developer notices a reduction in query speed in all database queries.

    The team’s technical lead determines that a multi-threaded and scalable caching solution should be used to offload the heavy read traffic. The solution needs to improve performance.

    Which solution will meet these requirements with the LEAST complexity?

    • Use Amazon ElastiCache for Memcached to offload read requests from the main database.

    • Replicate the data to Amazon DynamoDSet up a DynamoDB Accelerator (DAX) cluster.

    • Configure the Amazon RDS instances to use Multi-AZ deployment with one standby instance. Offload read requests from the main database to the standby instance.

    • Use Amazon ElastiCache for Redis to offload read requests from the main database.
