SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 .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?
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 Windows Server EC2 instances
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.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Rehost the application on Linux EC2 using Wine
Why it's wrong here
Wine is not supported for production workloads on AWS.
✓
Rehost the application on Windows Server EC2 instances
Why this is correct
Keeping the application on Windows Server EC2 avoids changes to the COM+ component.
Related concept
Static NAT maps one inside address to one outside address.
✗
Refactor the COM+ component to a REST API
Why it's wrong here
The stem says the component cannot be recompiled, so refactoring is not an option.
✗
Replatform the application to .NET Core and run on Linux
Why it's wrong here
COM+ components cannot run on Linux, so replatforming is not possible.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SAP-C02 NAT questions on configuration and troubleshooting.
