AWS Certified Solutions Architect – Associate (SAA-C03) — Question 829

A company runs its application on Oracle Database Enterprise Edition. The company needs to migrate the application and the database to AWS. The company can use the Bring Your Own License (BYOL) model while migrating to AWS. The application uses third-party database features that require privileged access.

A solutions architect must design a solution for the database migration.

Which solution will meet these requirements MOST cost-effectively?

Answer options

• A. Migrate the database to Amazon RDS for Oracle by using native tools. Replace the third-party features with AWS Lambda.
• B. Migrate the database to Amazon RDS Custom for Oracle by using native tools. Customize the new database settings to support the third-party features.
• C. Migrate the database to Amazon DynamoDB by using AWS Database Migration Service (AWS DMS). Customize the new database settings to support the third-party features.
• D. Migrate the database to Amazon RDS for PostgreSQL by using AWS Database Migration Service (AWS DMS). Rewrite the application code to remove the dependency on third-party features.

Correct answer: B

Explanation

Amazon RDS Custom for Oracle is the ideal solution because it supports the BYOL model and grants the privileged OS and database-level access required by the third-party features. Standard Amazon RDS for Oracle does not provide the administrative privileges needed for these features, while migrating to DynamoDB or PostgreSQL would incur significant costs and effort to rewrite the application code.
