- A
Migrate the application to run on Amazon EC2 instances joined to AWS Managed Microsoft AD.
AWS Managed Microsoft AD supports Windows Authentication with minimal code changes.
- B
Rewrite the application to .NET Core and deploy on AWS Elastic Beanstalk with Amazon RDS for SQL Server.
Why wrong: .NET Core is not backward compatible with .NET Framework 4.7; this requires major rewrite.
- C
Store session data in Amazon ElastiCache for Redis using the Redis Session State Provider.
ElastiCache for Redis with the Redis Session State Provider can replace in-process sessions with minimal code changes.
- D
Use Amazon Cognito with an Active Directory connector for authentication.
Why wrong: Cognito is designed for external identity providers, not for Windows Authentication within a Windows domain.
- E
Use Amazon DynamoDB to persist session state.
Why wrong: DynamoDB is not a native session store; custom code would be required.
Quick Answer
The correct answer combines AWS Managed Microsoft AD for Windows Authentication and Amazon ElastiCache for Redis with the Redis Session State Provider to migrate .NET Windows Authentication session state to AWS with minimal code changes. AWS Managed Microsoft AD integrates directly with EC2 or Elastic Beanstalk, preserving the existing Kerberos-based authentication flow without altering application code, while ElastiCache for Redis replaces in-process session storage by offloading state to a distributed, highly available cache using the same provider interface the .NET Framework already supports. On the SAP-C02 exam, this scenario tests your ability to modernize legacy authentication and session state using managed services while avoiding unnecessary rewrites—a common trap is choosing DynamoDB or Cognito, which require custom code or break Windows Authentication. Remember the mnemonic “AD for Auth, Redis for Rest” to recall that Active Directory handles identity and Redis handles state, keeping your migration clean and code-light.
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 migrating a legacy .NET Framework 4.7 application to AWS. The application currently uses Windows Authentication and stores session state in-process. The company wants to minimize code changes and use AWS managed services. Which TWO strategies should the company adopt?

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
Migrate the application to run on Amazon EC2 instances joined to AWS Managed Microsoft AD.
Option A is correct because AWS Managed Microsoft AD supports Windows Authentication and can integrate with EC2 or Elastic Beanstalk without code changes. Option D is correct because ElastiCache for Redis can be used as a distributed session store, replacing in-process session state with minimal code changes (using Redis Session State Provider). Option B is wrong because .NET Core is not compatible with .NET Framework 4.7 without significant rewrite. Option C is wrong because Cognito is for external identity providers, not Windows Authentication. Option E is wrong because DynamoDB is not a drop-in replacement for in-process sessions; it requires custom code.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Why it's wrong here
DynamoDB is not a native session store; custom code would be required.
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 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.
