The correct approach is to port the application to .NET Core and deploy on Amazon ECS with Linux containers. This works because .NET Core (now .NET 5+) is a cross-platform framework that supports Linux natively, allowing existing WCF services to be migrated with minimal code changes by targeting the CoreWCF library, which provides WCF compatibility on Linux. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of modernization trade-offs: the key trap is confusing compute platforms (like Fargate) with frameworks, or assuming Windows containers are required for WCF. The exam emphasizes minimizing refactoring while achieving Linux compatibility, so remember that .NET Core is the bridge, not a container type or serverless function. A useful memory tip is “CoreWCF on CoreOS” — if the goal is Linux and minimal changes, think .NET Core plus containers, not Lambda or Windows.
SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 modernizing a .NET Framework application to run on AWS. The application currently uses Windows Communication Foundation (WCF) services. The company wants to minimize code changes and run on Linux. Which approach should the company take?
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 the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Port the application to .NET Core and deploy on Amazon ECS with Linux containers.
Option B is correct because .NET Core (now .NET 5+) is cross-platform and supports Linux, allowing the company to run on Linux with minimal code changes. Option A is wrong because AWS Fargate is a compute platform, not a framework. Option C is wrong because Windows containers require Windows, not Linux. Option D is wrong because Lambda with custom runtime requires significant refactoring.
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.
✗
Use AWS App2Container to generate Windows containers and run on Amazon ECS with Windows.
Why it's wrong here
This keeps the application on Windows, not Linux.
✗
Rewrite the WCF services as AWS Lambda functions using a custom runtime.
Why it's wrong here
Rewriting as Lambda functions requires significant refactoring, not minimal changes.
✓
Port the application to .NET Core and deploy on Amazon ECS with Linux containers.
Why this is correct
.NET Core runs on Linux, enabling deployment on Linux containers with minimal changes.
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.
✗
Containerize the application using AWS Fargate and run on Windows containers.
Why it's wrong here
Fargate supports Windows containers, but the goal is to run on Linux, not Windows.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
