A large multi-media company is hosting their application on AWS. The application is currently using DynamoDB table for storage and retrieval of data. The data access for items in the table is currently in milliseconds, but the company wants to improve further on the access times. How can this be achieved?

Answer options:

A.Use larger DynamoDB tables.
B.Increase the Read capacity on the tables.
C.Increase the Write capacity on the tables.
D.Make use of the DAX feature.

Answer - D
The AWS Documentation mentions the following.
Amazon DynamoDB is designed for scale and performance. In most cases, the DynamoDB response times can be measured in single-digit milliseconds. However, certain use cases require response times in microseconds. DynamoDB Accelerator (DAX) delivers fast response times for accessing eventually consistent data for these use cases.
Option A is incorrect because using a larger table means providing more capacity, which does not help improve access times.
Options B and C are incorrect because the read and write capacities specify the number of reads and writes per second required for the application. This does not help to improve the access time.
