Oracle Cloud Infrastructure 2023 AI Foundations Associate — Question 26

You are planning the migration of a 19c Oracle Database from Amazon Web Services Relational Database Service (AWS RDS) using RMAN backups.
What is the correct sequence of operations?

Answer options

• A. Install the DB Cloud Backup Module on the AWS RDS instance and perform a backup directly to an Oracle Cloud Infrastructure (OCI) Object Storage bucket. Restore the backup from the OCI bucket to an OCI DB Service instance.
• B. Take an RMAN backup of the RDS DB local file system using the AWS tooling, and copy it directly to an Oracle Cloud Infrastructure (OCI) Object Storage bucket. Restore the backup from the OCI bucket to an OCI DB Service instance.
• C. Install the Oracle Secure Backup Cloud Module on the AWS RDS Instance and take an RMAN backup directly to an AWS S3 bucket. Copy the content of the S3 bucket to an Oracle Cloud Infrastructure (OCT) Object Storage bucket. Restore the backup from the OCI bucket to an OCI DB Service Instance.
• D. Take an RMAN backup of the RDS DB local file system using the AWS tooling, and move it to an AWS S3 bucket. Copy the content of the S3 bucket to an Oracle Cloud Infrastructure (OCI) Object Storage bucket. Restore the backup from the OCI bucket to an OCI DB Service instance.

Correct answer: D

Explanation

The correct sequence is to first take an RMAN backup using AWS tooling, then move it to an AWS S3 bucket before transferring to an OCI Object Storage bucket, and finally restore it to an OCI DB Service instance. Options A and C incorrectly suggest backing up directly to OCI or using the wrong backup module, while option B misses the step of moving the backup to the S3 bucket first.
