The answer is to use Windows containers on Amazon ECS with the ECS-optimized Windows Server AMI, because this is the only approach that fully supports .NET Framework 4.7 applications with COM+ components and Windows authentication. Windows containers on ECS run on Windows Server Core, which provides the necessary Windows kernel and COM+ infrastructure that Linux containers and serverless options lack. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your understanding of the hard boundary between .NET Framework (Windows-only) and .NET Core/.NET 5+ (cross-platform), and it often appears as a distractor where candidates mistakenly choose Elastic Beanstalk or Lambda. A common trap is assuming that any "container" solution works, but Linux containers cannot host COM+ or full .NET Framework. Memory tip: "COM+ means Windows+ — never try to run legacy COM on Linux."
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 legacy .NET Framework 4.7 application to AWS. The application uses Windows authentication and COM+ components. Which migration approach is most suitable?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Windows containers on Amazon ECS with Amazon ECS-optimized Windows Server AMI
Windows containers on Amazon ECS with Windows Server Core support .NET Framework applications and COM+. Option A is wrong because Linux containers do not support .NET Framework. Option B is wrong because Elastic Beanstalk with Linux does not support .NET Framework. Option D is wrong because Lambda does not support full .NET Framework.
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.
✗
Replatform to .NET Core on AWS Elastic Beanstalk (Linux)
Why it's wrong here
.NET Core is not fully compatible with .NET Framework and COM+.
✓
Use Windows containers on Amazon ECS with Amazon ECS-optimized Windows Server AMI
Why this is correct
Windows containers support .NET Framework and COM+ components.

✗
Refactor to run on AWS Lambda with .NET Core 3.1
Why it's wrong here
Lambda does not support full .NET Framework or COM+.
✗
Containerize with Linux containers on Amazon ECS
Why it's wrong here
.NET Framework requires Windows containers.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.

Variation 1. A company is migrating a legacy .NET Framework 4.8 application to AWS. The application uses Windows authentication integrated with Active Directory and relies on a shared file system for configuration files. The company wants to minimize operational overhead and use managed services. Which combination of AWS services should the company use to modernize the application?
hard
A.AWS Managed Microsoft AD, Amazon EFS, and AWS Elastic Beanstalk for .NET on Windows
B.Amazon Cognito, Amazon RDS for SQL Server, and AWS Lambda
C.AWS Directory Service for Microsoft AD, Amazon S3, and AWS App Runner
✓ D.AWS Managed Microsoft AD, Amazon FSx for Windows File Server, and AWS Elastic Beanstalk for .NET on Windows
Why D: Option C is correct: AWS Managed Microsoft AD provides Windows authentication, FSx for Windows File Server provides a managed shared file system, and App Runner is not suitable for .NET; Elastic Beanstalk with Windows platform supports .NET and reduces overhead. Option A uses EFS which does not support Windows authentication natively. Option B uses RDS for SQL Server which is not needed. Option D uses S3 which cannot replace a shared file system for Windows apps.
Variation 2. A company is migrating a .NET application from Windows Server to Linux on EC2. The application uses a proprietary COM+ component that cannot be recompiled. Which migration path should they take?
medium
A.Rehost the application on Linux EC2 using Wine
✓ B.Rehost the application on Windows Server EC2 instances
C.Refactor the COM+ component to a REST API
D.Replatform the application to .NET Core and run on Linux
Why B: Since the COM+ component cannot be recompiled and is Windows-specific, the only viable option is to remain on Windows using EC2 (Rehost). Option A (Replatform to .NET Core on Linux) is impossible because COM+ does not run on Linux. Option B (Refactor the component) violates the constraint. Option D (Rehost using Linux) is invalid.
