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 instances and migrate the database using AWS Database Migration Service (DMS) with ongoing replication.
Rehosting (lift-and-shift) the application on Amazon EC2 allows the proprietary database to run without modification. Using AWS Database Migration Service (DMS) with ongoing replication minimizes downtime by keeping the database synchronized until cutover. Option A is incorrect because the proprietary database is not supported by Amazon RDS, so migrating to RDS is not feasible without changing the database engine. Option C is incorrect because refactoring to Amazon Aurora would require modifying the application code to use Aurora's query interface, resulting in significant changes. Option D is incorrect because replacing the database with Amazon DynamoDB would necessitate rewriting the entire database access layer, which is not minimal change.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Migrate the database to Amazon RDS with a compatible engine and modify connection strings.
Why it's wrong here
The database is not supported by RDS, so this option is not feasible.
- ✓
Rehost the application on Amazon EC2 instances and migrate the database using AWS Database Migration Service (DMS) with ongoing replication.
Why this is correct
Rehosting on EC2 allows the same database engine, and DMS with replication minimizes downtime.
- ✗
Refactor the application to use Amazon Aurora and modify the code to use the Aurora query interface.
Why it's wrong here
Refactoring would require significant application changes and is not minimal.
- ✗
Replace the database with Amazon DynamoDB and rewrite database access layer.
Why it's wrong here
Replacing the database would require application changes and is not minimal.
