An entertainment company is using Amazon DynamoDB to store media metadata.The application is read intensive and experiencing delays.The company does not have staff to handle additional operational overhead and needs to improve the performance efficiency of DynamoDB without reconfiguring the application.

What should a solutions architect recommend to meet this requirement?

Use Amazon ElastiCache for Redis.

Use Amazon DynamoDB Accelerator (DAX).

Replicate data by using DynamoDB global tables.

Use Amazon ElastiCache for Memcached with Auto Discovery enabled.

Explanations:

Amazon ElastiCache for Redis is a caching solution that requires additional operational management and may not integrate seamlessly with DynamoDB without reconfiguration.

Amazon DynamoDB Accelerator (DAX) is designed to improve the performance of DynamoDB by providing in-memory caching without requiring changes to the existing application. It reduces read latencies significantly.

While DynamoDB global tables allow for data replication across regions, this approach does not specifically address read performance and could introduce additional complexity.

Amazon ElastiCache for Memcached would also add operational overhead and is not specifically optimized for DynamoDB, which could lead to additional management requirements.
