AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

Enabling DynamoDB Point-in-Time Recovery (PITR) provides continuous backups that let administrators restore the table to any second in the preceding 35 days. Restores create a new table in minutes, easily meeting a 15-minute RTO without manual backup scheduling or additional infrastructure. Hourly on-demand backups would still leave gaps of up to 59 minutes and would increase storage and API costs. Streaming table updates to S3 and replaying them would require building and operating custom pipelines and would not guarantee the target RTO. Creating a global table offers high availability but does not give the ability to roll back to an arbitrary point in the past; it also incurs additional write-replication costs. Therefore, enabling PITR is the most economical and operationally simple solution.
