Quick Answer
The answer is AWS AD Connector. While the term “replicate” in the search intent for Active Directory replication for SAP authentication can be misleading, AD Connector is the correct AWS service because it acts as a proxy that forwards authentication requests from AWS Managed Microsoft AD to your on-premises Active Directory, enabling seamless SAP user authentication without actually copying directory data. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding that AWS does not support native AD replication; instead, you use a trust relationship or a proxy service like AD Connector to bridge on-premises and cloud directories for SAP workloads. A common trap is confusing replication with proxying—AD Connector does not replicate, it relays credentials in real time, which is exactly what SAP authentication requires when you cannot or do not want to synchronize user objects. Memory tip: think of AD Connector as a “phone line” that connects your SAP app to the on-premises directory without moving the directory itself.
This PAS-C01 practice question tests your understanding of migration. 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 SAP applications to AWS and needs to replicate data from on-premises Active Directory to AWS Managed Microsoft AD for authentication. Which AWS service should be used?
AWS Transit Gateway
Why wrong: Transit Gateway is for network connectivity.
AWS Directory Service for Microsoft Active Directory
Why wrong: Managed AD is a separate directory, not replication.
AWS Resource Access Manager (RAM)
Why wrong: RAM is for sharing resources, not directory.
AWS AD Connector
AD Connector allows on-premises users to authenticate to AWS applications.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
AWS AD Connector
AWS AD Connector proxies requests to on-premises AD, not replicate. Option B is wrong because AWS RAM is for sharing resources. Option C is wrong because AWS Transit Gateway is for network connectivity. Option D is wrong because AWS Directory Service for Microsoft AD is a managed directory, but the requirement is replication, not proxy. The correct answer is AWS AD Connector for directory synchronization, but note: AD Connector does not replicate, it proxies. However, the best option for 'replicate' might be to use AWS Directory Service's two-way trust, but that is not listed. The question is tricky: AD Connector is for authentication proxy, not replication. Actually, the correct service for replication is AWS Managed Microsoft AD with a trust relationship. But among options, none directly replicate. However, AD Connector is the closest for authentication purposes. The question says 'replicate data', which might be misinterpreted. Actually, AWS does not replicate Active Directory data; it can create a trust. For the purpose of this exam, AD Connector is used to allow on-premises users to authenticate to AWS applications. So I'll stick with AD Connector.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
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
Transit Gateway is for network connectivity.
AWS Directory Service for Microsoft Active Directory
Why it's wrong here
Managed AD is a separate directory, not replication.
AWS Resource Access Manager (RAM)
Why it's wrong here
RAM is for sharing resources, not directory.
AWS AD Connector
Why this is correct
AD Connector allows on-premises users to authenticate to AWS applications.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
