The correct solution is to set up AWS Managed Microsoft AD with a two-way trust to on-premises Active Directory over Direct Connect. This works because the two-way trust allows the .NET application running on Amazon ECS to authenticate users against AWS Managed Microsoft AD while the actual credential validation occurs on-premises via the trust relationship, ensuring credentials never leave the corporate network as required. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of hybrid identity integration, specifically how to migrate .NET applications using Windows authentication without compromising security. A common trap is choosing AD Connector, which proxies authentication but does not keep credentials on-premises—it passes them to AWS. Remember the key distinction: a two-way trust keeps the authentication source on your side of the Direct Connect link, while a proxy sends credentials across. Memory tip: “Trust keeps it local, proxy sends it over.”
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 legacy .NET application by containerizing it on Amazon ECS. The application currently uses Windows authentication against on-premises Active Directory. After migrating, the application needs to authenticate users against AWS Managed Microsoft AD. The security team requires that credentials never leave the corporate network. Which solution should the company implement?

Correct answer & explanation
✓
Set up AWS Managed Microsoft AD with a two-way trust to on-premises AD over Direct Connect.
Option A is correct because AWS Managed Microsoft AD connects via Direct Connect. Option B is wrong because AD Connector proxies but does not keep credentials on-premises. Option C is wrong because Simple AD lacks features. Option D is wrong because on-premises AD is not integrated.
Key principle: 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.
