SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is migrating a legacy application to AWS. The application uses a proprietary database that is not supported by Amazon RDS. The company wants to minimize changes and use a managed service. Which TWO options should the company consider? (Choose TWO.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Run the database on Amazon EC2 with Amazon EBS volumes.
Options C and E are correct. Option C allows running the database on EC2 with EBS, providing full control and compatibility with any database engine, minimizing changes. Option E uses an AWS Marketplace third-party solution that offers a managed service for the specific database. Option A is incorrect because Amazon RDS does not support custom engines; it only supports specific database engines. Option B is incorrect because Amazon S3 is object storage, not a database, and S3 Select is for querying objects, not suitable as a database replacement. Option D is incorrect because DynamoDB is a NoSQL database that would require significant application changes.
