You are working as an AWS consultant in an E-Commerce organization. Your organization is planning to migrate its database from on-premises data centers to Amazon RDS. The automated backup helps to restore the Database to any specific time during the backup retention period in Amazon RDS. Which of the following actions are performed as a part of the Amazon RDS automated backup process?

Answer options:

A.AWS creates a storage volume snapshot of the database instance during the backup window once a day. AWS RDS also captures transactions logs and uploads them to S3 buckets every 5 minutes.
B.AWS creates a full snapshot of the database every 12 hours during the backup window, captures transactions logs throughout the day, and stores them in S3 buckets.
C.AWS creates a full daily snapshot during the backup window. With the snapshot, the RDS instance can be restored at any time.
D.AWS creates a storage volume snapshot of the database instance every 12 hours during the backup window, captures transactions logs throughout the day, and stores them in S3 buckets.

Correct Answer – A
During automated backup, Amazon RDS creates a storage volume snapshot of the entire Database Instance. RDS uploads transaction logs for DB instances to Amazon S3 every 5 minutes. To restore a DB instance at a specific point in time, a new DB instance is created using the DB snapshot.
You can also use AWS Backup to manage backups of Amazon RDS DB instances. If your DB instance is associated with a backup plan in AWS Backup, that backup plan is used for point-in-time recovery. 
Option B is incorrect as RDS automated backup does not take a full snapshot every 12 hours.
Option C is incorrect as this option does not mention the transaction logs captured in the automated backup process.
Option A is more accurate.
Option D is incorrect as AWS performs storage volume snapshots daily, not every 12 hours.
