To improve the game’s performance, which AWS service can you use to reduce DynamoDB response times from milliseconds to microseconds?

A popular mobile game uses CloudFront, Lambda, and DynamoDB for its backend services. The player data is persisted on a DynamoDB table and the static assets are distributed by CloudFront. However, there are a lot of complaints that saving and retrieving player information is taking a lot of time.

To improve the game’s performance, which AWS service can you use to reduce DynamoDB response times from milliseconds to microseconds?
A . Amazon DynamoDB Accelerator (DAX)
B . DynamoDB Auto Scaling
C . Amazon ElastiCache
D . AWS Device Farm

Answer: A

Explanation:

Amazon DynamoDB Accelerator (DAX) is a fully managed, highly available, in-memory cache that can reduce Amazon DynamoDB response times from milliseconds to microseconds, even at millions of requests per second.

Amazon ElastiCache is incorrect because although you may use ElastiCache as your database cache, it will not reduce the DynamoDB response time from milliseconds to microseconds as compared with DynamoDB DAX.

AWS Device Farm is incorrect because this is an app testing service that lets you test and interact with

your Android, iOS, and web apps on many devices at once, or reproduce issues on a device in real time.

DynamoDB Auto Scaling is incorrect because this is primarily used to automate capacity management

for your tables and global secondary indexes.
