AWS Certified Solutions Architect – Associate (SAA-C03) — Question 65

A company runs an Oracle database on premises. As part of the company’s migration to AWS, the company wants to upgrade the database to the most recent available version. The company also wants to set up disaster recovery (DR) for the database. The company needs to minimize the operational overhead for normal operations and DR setup. The company also needs to maintain access to the database's underlying operating system.
Which solution will meet these requirements?

Answer options

• A. Migrate the Oracle database to an Amazon EC2 instance. Set up database replication to a different AWS Region.
• B. Migrate the Oracle database to Amazon RDS for Oracle. Activate Cross-Region automated backups to replicate the snapshots to another AWS Region.
• C. Migrate the Oracle database to Amazon RDS Custom for Oracle. Create a read replica for the database in another AWS Region.
• D. Migrate the Oracle database to Amazon RDS for Oracle. Create a standby database in another Availability Zone.

Correct answer: C

Explanation

The correct answer is C because Amazon RDS Custom for Oracle allows for maintaining the underlying operating system, which meets the requirement of operational access. Option A does not provide the same level of managed service benefits as RDS. Option B does not allow access to the underlying OS, and option D, while providing a standby database, does not meet the requirement for a different AWS Region for disaster recovery.
