SAP-C02 Practice Question: Accelerate Workload Migration and Modernization

The company has a complex Active Directory structure with multiple domains, group policies, and trusts with external directories. Which migration approach should the company use?
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
✓
Establish a forest trust between the on-premises AD and AWS Managed Microsoft AD, then gradually move resources to AWS
Setting up a trust between the on-premises AD and AWS Managed Microsoft AD allows gradual migration of resources. This maintains existing authentication and group policies during the transition. Replacing AD with IAM is not suitable for Windows workloads. Replicating the entire AD structure via AD Connector is not possible. A full rebuild is complex and risky.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Replace Active Directory with AWS Identity and Access Management (IAM) for all authentication
Why it's wrong here
IAM is not a replacement for AD features like group policies and domain-joined machines.
- ✓
Establish a forest trust between the on-premises AD and AWS Managed Microsoft AD, then gradually move resources to AWS
Why this is correct
Correct. A trust allows seamless coexistence and incremental migration.
- ✗
Rebuild the entire Active Directory structure from scratch in AWS Managed Microsoft AD
Why it's wrong here
Rebuilding from scratch is error-prone and causes disruption.
- ✗
Use AD Connector to proxy authentication requests from AWS to the on-premises AD
Why it's wrong here
AD Connector does not provide a full AD directory; it only proxies authentication.
