Topic 1 Question 177
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.

DAX stands for DynamoDB Accelerator, and it's like a turbo boost for your DynamoDB tables. It's a fully managed, in-memory cache that speeds up the read and write performance of your DynamoDB tables, so you can get your data faster than ever before.
👍 10techhb2022/12/25 B DAX is a fully managed, highly available, in-memory cache for DynamoDB that delivers lightning-fast performance and consistent low-latency responses. It provides fast performance without requiring any application reconfiguration

To improve the performance efficiency of DynamoDB without reconfiguring the application, a solutions architect should recommend using Amazon DynamoDB Accelerator (DAX) which is Option B as the correct answer.
DAX is a fully managed, in-memory cache that can be used to improve the performance of read-intensive workloads on DynamoDB. DAX stores frequently accessed data in memory, allowing the application to retrieve data from the cache rather than making a request to DynamoDB. This can significantly reduce the number of read requests made to DynamoDB, improving the performance and reducing the latency of the application.
