The correct answer is to combine AWS Managed Microsoft AD with AD Connector. AWS Managed Microsoft AD allows you to deploy fully managed Active Directory in multiple AWS regions, creating a mesh of domain controllers that provide low-latency authentication for users across geographic boundaries. AD Connector then acts as a proxy to bridge these AWS-based directories back to your existing on-premises Active Directory, enabling seamless SSO without requiring complex trust relationships or directory synchronization. On the SAP-C02 exam, this scenario tests your understanding of hybrid identity architectures under high-availability constraints; a common trap is selecting AWS SSO or Cognito, but those handle external federation or customer identities, not core multi-region AD authentication for internal users. Remember the key pairing: Managed AD for the multi-region footprint, AD Connector for the on-premises bridge. Memory tip: think “Managed for the map, Connector for the connection.”
SAP-C02 Practice Question: Design Solutions for Organizational Complexity
This SAP-C02 practice question tests your understanding of design solutions for organizational complexity. 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 multinational corporation is migrating its on-premises Active Directory to AWS. The company requires a solution that supports multi-region authentication for thousands of users and integrates with existing on-premises Active Directory for seamless SSO. The solution must be highly available and provide low-latency authentication. Which TWO AWS services should be combined to meet these requirements? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AD Connector
AWS Managed Microsoft AD can be deployed in multiple regions and linked to on-premises Active Directory via AD Connector. AWS Identity and Access Management (IAM) integrates with AD for SSO. Option A (AWS SSO) is a separate service that can also be used but is not required; Option C (Cognito) is for external users; Option E (Direct Connect) is a network service. Correct: B and D.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Amazon Cognito
Why it's wrong here
Amazon Cognito is for external identity providers and user pools, not for on-premises AD integration.
✗
AWS Direct Connect
Why it's wrong here
Direct Connect provides dedicated network connection but does not handle authentication or SSO.
✓
AD Connector
Why this is correct
AD Connector connects AWS services to on-premises AD, enabling SSO and authentication.
Related concept
Static NAT maps one inside address to one outside address.
✗
AWS Single Sign-On (SSO)
Why it's wrong here
AWS SSO is a separate SSO service that can integrate with AD, but it is not required when using AD Connector and IAM.
✓
AWS Managed Microsoft AD
Why this is correct
AWS Managed Microsoft AD provides a fully managed Active Directory in multiple regions, supports multi-region authentication.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SAP-C02 NAT questions on configuration and troubleshooting.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A multinational corporation is migrating its on-premises Active Directory (AD) to AWS Managed Microsoft AD. The company has a hub-and-spoke VPC topology with a central transit gateway. The AD domain controllers must be deployed in two different AWS Regions for disaster recovery. The corporate security policy requires that all AD traffic between Regions must traverse the transit gateway and be inspected by a third-party firewall appliance deployed in the inspection VPC. Which architecture meets these requirements?
medium
A.Deploy AD in two Regions and use a VPN connection between the VPCs to replicate data.
B.Deploy a single AD domain in one Region and use AD replication over a VPC peering connection to a second Region.
C.Deploy AD in two Regions, attach both VPCs to the transit gateway, and enable cross-Region transit gateway peering. Use route tables to direct AD traffic through the inspection VPC.
✓ D.Deploy AD in two Regions, attach both VPCs to a transit gateway in the primary Region, and use a transit gateway inter-Region peering attachment. Configure route tables to force traffic through the inspection VPC in the primary Region.
Why D: Option D is correct because it uses a transit gateway in the primary Region with an inter-Region peering attachment to the secondary Region, allowing AD traffic to be routed through the inspection VPC in the primary Region for firewall inspection. This meets the security policy requirement that all cross-Region AD traffic must traverse the transit gateway and be inspected by the third-party firewall appliance.
Variation 2. A multinational corporation is migrating its on-premises Active Directory to AWS Managed Microsoft AD. The company has multiple VPCs in different AWS Regions, and all VPCs must be able to authenticate against the same directory. The directory must be highly available and support automatic failover. What is the MOST operationally efficient solution?
hard
A.Use AWS Directory Service AD Connector in each VPC and point to an on-premises Active Directory.
✓ B.Deploy AWS Managed Microsoft AD in each Region using multi-Region replication. Configure the directory as a global directory.
C.Deploy AWS Managed Microsoft AD in one Region. Create VPC peering connections to all other VPCs.
D.Deploy AWS Managed Microsoft AD in one Region. Configure VPN connections from each VPC to this directory.
Why B: AWS Managed Microsoft AD with multi-Region replication provides a single global directory that spans multiple Regions, enabling automatic failover and high availability. This is the most operationally efficient solution because it eliminates the need for complex networking (VPC peering or VPNs) and allows all VPCs to authenticate against the same directory natively, with replication handled by AWS.
