SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is migrating a legacy .NET Framework 4.7 web application to AWS. The application currently runs on Windows Server 2012 R2 with IIS and uses SQL Server Express for local storage. The company wants to minimize re-architecture and reduce operational overhead. Which migration strategy should the company use?
⚠ Common exam trap
Many exam-takers choose replatforming (Option C) thinking it reduces overhead, but it actually requires modifying the database connection string and handling Multi-AZ failover, which adds re-architecture effort beyond a simple lift-and-shift.

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 Windows instances using an AWS Migration Acceleration Program (MAP) partner tool.
Rehosting (lift-and-shift) the .NET Framework 4.7 application to Amazon EC2 Windows instances minimizes re-architecture and reduces operational overhead. The application is tightly coupled to Windows Server and IIS, and SQL Server Express is a local database; rehosting preserves the existing architecture without code changes. Using an AWS MAP partner tool streamlines the migration process, aligning with the goal of minimizing changes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Retire the application and replace it with a SaaS-based solution.
Why it's wrong here
Retiring is not an option since the application is still needed.
- ✗
Refactor the application to use .NET Core and deploy on Linux containers with Amazon ECS.
Why it's wrong here
Refactoring would require significant code changes and does not minimize re-architecture.
- ✗
Replatform the application to use AWS Elastic Beanstalk with a SQL Server Express Multi-AZ RDS instance.
Why it's wrong here
Replatforming would still require changes to the database setup and may not minimize re-architecture.
- ✓
Rehost the application on Amazon EC2 Windows instances using an AWS Migration Acceleration Program (MAP) partner tool.
Why this is correct
Rehosting lifts and shifts the application with minimal changes, reducing operational overhead.

| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
