SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is migrating a legacy .NET application to AWS. The application uses Windows authentication and stores session state in-memory. The company wants to minimize code changes and use AWS managed services. Which combination of AWS services should the company use to modernize the application's authentication and session management?
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
✓
AWS Managed Microsoft AD and Amazon ElastiCache for Redis
AWS Managed Microsoft AD allows the application to continue using Windows authentication with minimal code changes, and Amazon ElastiCache for Redis provides a distributed, high-performance session store that can replace in-memory session state. Option A is incorrect because AD Connector only proxies authentication requests to an on-premises Active Directory, not providing a managed AD service, and Amazon RDS is not designed for session storage. Option B is incorrect because Amazon Cognito is intended for external identity federation (e.g., social logins), not Windows authentication. Option C is incorrect because AWS IAM is for managing access to AWS resources, not for application-level Windows authentication.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Directory Service for Microsoft Active Directory (AD Connector) and Amazon RDS
Why it's wrong here
AD Connector proxies to on-premises AD, not a managed directory; RDS is not for session storage.
- ✗
Amazon Cognito and Amazon DynamoDB
Why it's wrong here
Cognito is for external identity providers, not Windows authentication; DynamoDB can store sessions but requires code changes.
- ✗
AWS IAM and Amazon DynamoDB
Why it's wrong here
IAM is for AWS API authentication, not Windows authentication; DynamoDB requires code changes for session storage.
- ✓
AWS Managed Microsoft AD and Amazon ElastiCache for Redis
Why this is correct
Managed Microsoft AD provides native Windows authentication; ElastiCache for Redis supports session management with minimal code changes.
