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
✓
Rehost the application on Amazon EC2 with MySQL installed on the same instance
Rehost (lift-and-shift) migrates the application as-is to EC2, keeping MySQL on the same instance to minimize code changes. Option B (Retire) is not a migration strategy. Option C (Refactor) requires code changes to adapt to serverless and DynamoDB. Option D (Replatform) moves the database to RDS, which may require code changes due to different database configuration or features.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Rehost the application on Amazon EC2 with MySQL installed on the same instance
Why this is correct
Rehosting moves the application without changes, minimizing risk.
- ✗
Retire the application and replace it with a SaaS alternative
Why it's wrong here
Retiring is not appropriate as the company wants to migrate the application.
- ✗
Refactor the application to use a serverless architecture with AWS Lambda and Amazon DynamoDB
Why it's wrong here
Refactoring requires significant code changes, increasing risk and effort.
- ✗
Replatform the application by moving the database to Amazon RDS for MySQL
Why it's wrong here
Replatforming the database may require connection string changes and additional testing.
