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 Directory Service for Microsoft Active Directory
AWS Directory Service for Microsoft Active Directory is the correct service because it provides a managed Active Directory in AWS that can be configured with a forest trust to on-premises Active Directory, enabling replication of directory data. This allows authentication using on-premises credentials in AWS. Option A (AWS Transit Gateway) is for network connectivity, not directory replication. Option C (AWS Resource Access Manager) is used for sharing resources across accounts. Option D (AWS AD Connector) only proxies authentication requests and does not replicate data. Therefore, the best answer is AWS Directory Service for Microsoft Active Directory.
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 Transit Gateway
Why it's wrong here
AWS Transit Gateway provides network connectivity between VPCs and on-premises networks, but does not replicate directory data or handle authentication.
- ✓
AWS Directory Service for Microsoft Active Directory
Why this is correct
AWS Directory Service for Microsoft Active Directory is a managed service that can be set up with a trust relationship to on-premises AD, allowing replication of directory objects, meeting the requirement.
- ✗
AWS Resource Access Manager (RAM)
Why it's wrong here
AWS Resource Access Manager is used for sharing resources across AWS accounts, not for directory replication or authentication.
- ✗
AWS AD Connector
Why it's wrong here
AWS AD Connector proxies authentication requests from AWS to on-premises AD but does not replicate directory data, so it does not satisfy the requirement to replicate data.
