Your company asked you to create a mobile application. The application is built to work with DynamoDB as the backend and Javascript as the frontend. During the application`s usage, you notice that sometimes during the daytime, the write requests are throttled because of low provisioned write capacity. How can you effectively resolve this problem of the DynamoDB in the easiest way?

Answer options:

A.Enable DynamoDB Auto Scaling to meet the requirements.
B.Increase write capacity of DynamoDB to meet the peak loads.
C.Use the SQS service to read messages in the queue and write these to DynamoDB.D.Launch DynamoDB in Multi-AZ configuration with a global index to balance writes.

Answer: A
Option A is correct because users can enable Auto Scaling in DynamoDB. Please refer to the below link-
https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/AutoScaling.html
Option B is incorrect because just increasing the write capacity of the DynamoDB table would not satisfy the requirement "effectively manage DynamoDB". The problem only happens during the daytime. So there is a waste of provisioned resources when there are few requests in the night.
Option C is incorrect. Because you have to create a new SQS queue and modify the related logic for DynamoDB. This option is not the easiest one.
Option D is incorrect because launching a DynamoDB table in a Multi-AZ configuration with a global index would only increase data availability and would not solve the write contention issue.

Note:
The question is asking "....how to manage DynamoDB"
The new feature that has been added recently is "autoscaling of dynamodb" which would help to solve this issue
Please refer to the link- https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/AutoScaling.html
