Answer: Enable DynamoDB point-in-time recovery for precise RPO restoration.
Option B is the correct answer. Amazon DynamoDB point-in-time recovery (PITR) allows you to back up your table data continuously and restore to any point in time within the last 35 days. This meets the 15-minute Recovery Point Objective (RPO) as it allows for near real-time data recovery. Additionally, restoring data from a point in time can typically be done within an hour, meeting the Recovery Time Objective (RTO) of 1 hour. Thus, configuring DynamoDB point-in-time recovery is the optimal solution.
