Question 8

____________pricing offers significant savings over the normal price of DynamoDB provisioned throughput capacity.

Accepted Answer

Reserved Capacity pricing offers significant savings over the normal price of DynamoDB provisioned throughput capacity by allowing customers to commit to a certain amount of capacity for a term, typically one or three years.

Question 9

Question 17

In order for a table write to succeed, the provisioned throughput settings for the table and global secondary indexes, in DynamoDB, must have__________; otherwise, the write to the table will be throttled.

Accepted Answer
