SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is planning to migrate a legacy application to AWS. The application runs on a single server with a monolithic architecture and uses an Oracle database. The migration team wants to reduce licensing costs and improve scalability. Which TWO strategies should the team consider?
⚠ Common exam trap
A common mix-up: candidates confuse 'replatforming' (option A and C) with 'refactoring' (option B) or assume that rehosting with Oracle BYOL (option E) reduces costs, when in fact BYOL still requires existing licenses and does not eliminate licensing expenses.
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
✓
Replatform the application to use AWS Elastic Beanstalk and Amazon RDS for PostgreSQL.
Replatforming the application to AWS Elastic Beanstalk reduces operational overhead by automating capacity provisioning, load balancing, and scaling, while migrating from Oracle to Amazon RDS for PostgreSQL eliminates Oracle licensing costs and provides a managed database service with built-in high availability and scalability. This approach directly addresses the company's goals of reducing licensing costs and improving scalability without requiring a full application rewrite.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Replatform the application to use AWS Elastic Beanstalk and Amazon RDS for PostgreSQL.
Why this is correct
Reduces operational overhead and licensing costs.
- ✗
Refactor the application into microservices and use Amazon DynamoDB for data storage.
Why it's wrong here
High refactoring effort; not directly reducing licensing costs.
- ✓
Replatform the database to Amazon RDS for PostgreSQL and refactor the application to use it.
Why this is correct
Reduces licensing costs and improves scalability.
- ✗
Rehost the application on Amazon EC2 and use Amazon RDS for Oracle with license-included.
Why it's wrong here
License-included is more expensive.
- ✗
Rehost the application on Amazon EC2 and use Amazon RDS for Oracle with BYOL.
Why it's wrong here
Still uses Oracle licensing; does not reduce costs.
