A company is planning to use an Amazon DynamoDB table for data storage.The company is concerned about cost optimization.The table will not be used on most mornings.In the evenings, the read and write traffic will often be unpredictable.When traffic spikes occur, they will happen very quickly.
What should a solutions architect recommend?
Create a DynamoDB table in on-demand capacity mode.
Create a DynamoDB table with a global secondary index.
Create a DynamoDB table with provisioned capacity and auto scaling.
Create a DynamoDB table in provisioned capacity mode, and configure it as a global table.
Explanations:
On-demand capacity mode is ideal for unpredictable and sporadic traffic patterns, allowing cost control.
Global secondary indexes improve query flexibility but do not address cost optimization or traffic spikes.
Provisioned capacity with auto scaling can manage traffic but may incur higher costs due to idle capacity.
Global tables provide multi-region availability but do not optimize for unpredictable traffic or cost.
My best guess is:
Create a DynamoDB table in on-demand capacity mode.
I conclude that the answer is:
Create a DynamoDB table in on-demand capacity mode.
