Topic 1 Question 79
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.

- 正解だと思う選択肢: A
On-demand mode is a good option if any of the following are true:
- You create new tables with unknown workloads.
- You have unpredictable application traffic.
- You prefer the ease of paying for only what you use.

A - On demand is the answer - https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/HowItWorks.ReadWriteCapacityMode.html#HowItWorks.OnDemand B - not related with the unpredictable traffic C - provisioned capacity is recommended for known patterns. Not the case here. D - same as C

Use pattern is not unknown, it was well laid out in the question. I think C is the correct answer.
