- A
Refactor the application to .NET Core and use Amazon RDS for MySQL to eliminate Windows licensing.
Why wrong: Refactoring is significant and MySQL may not support all stored procedures.
- B
Rehost the application on Amazon EC2 and the database on EC2 with SQL Server using Bring Your Own License (BYOL).
This minimizes changes and leverages existing licenses.
- C
Rearchitect the application to microservices and use Amazon DynamoDB for the database.
Why wrong: Rearchitecting is too disruptive for minimizing refactoring.
- D
Replatform the database to Amazon Aurora with PostgreSQL compatibility to reduce licensing costs.
Why wrong: Aurora PostgreSQL would require rewriting stored procedures and may not be compatible.

SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is migrating a monolithic .NET application to AWS. The application uses a SQL Server database with complex stored procedures and tightly coupled components. The migration team wants to minimize refactoring and reduce licensing costs. Which migration strategy should the team use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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 and the database on EC2 with SQL Server using Bring Your Own License (BYOL).
Option B is correct because rehosting (lift-and-shift) the monolithic .NET application on Amazon EC2 and the SQL Server database on EC2 with BYOL minimizes refactoring effort and reduces licensing costs by leveraging existing SQL Server licenses. This strategy avoids the complexity of rewriting stored procedures or decoupling tightly coupled components, which is critical for a migration focused on speed and cost reduction.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Refactor the application to .NET Core and use Amazon RDS for MySQL to eliminate Windows licensing.
Why it's wrong here
Refactoring is significant and MySQL may not support all stored procedures.
- ✓
Rehost the application on Amazon EC2 and the database on EC2 with SQL Server using Bring Your Own License (BYOL).
Why this is correct
This minimizes changes and leverages existing licenses.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Rearchitect the application to microservices and use Amazon DynamoDB for the database.
Why it's wrong here
Rearchitecting is too disruptive for minimizing refactoring.
- ✗
Replatform the database to Amazon Aurora with PostgreSQL compatibility to reduce licensing costs.
Why it's wrong here
Aurora PostgreSQL would require rewriting stored procedures and may not be compatible.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose replatforming (Option D) thinking it reduces licensing costs, but they overlook the need to refactor SQL Server-specific stored procedures for PostgreSQL compatibility, which violates the 'minimize refactoring' requirement.
Detailed technical explanation
How to think about this question
Under the hood, rehosting on EC2 with BYOL allows the company to use their existing SQL Server licenses under Microsoft's License Mobility through Software Assurance, avoiding new licensing costs. The tightly coupled components and complex stored procedures remain unchanged, preserving the application's runtime behavior without requiring schema or query rewrites. In a real-world scenario, this approach is ideal when the migration timeline is tight and the team lacks resources for code modifications, as it leverages the same OS and database engine versions.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
