SAP-C02 Design for New Solutions Practice Question
A company is designing a hybrid cloud solution that extends its on-premises data center to AWS. The company has a 10 Gbps AWS Direct Connect connection and needs to securely connect multiple VPCs and on-premises networks with transitive routing. The solution must be highly available and use AWS managed services. Which TWO components should the company include in the design? (Choose TWO.)
⚠ Common exam trap
Candidates often confuse VPC peering with transitive routing, or assume that Direct Connect alone provides transitive connectivity, but neither VPC peering nor a standalone Direct Connect connection offers the transitive routing required for a multi-VPC hybrid architecture.
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 Transit Gateway with attachments for each VPC and the Direct Connect Gateway.
AWS Transit Gateway provides transitive routing between multiple VPCs and on-premises networks, eliminating the need for complex peering meshes. Option E is correct because attaching a Direct Connect Gateway to the Transit Gateway allows the single 10 Gbps Direct Connect connection to be shared across all attached VPCs, enabling centralized, highly available connectivity.
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 Global Accelerator endpoints in each VPC.
Why it's wrong here
Global Accelerator is for traffic acceleration, not connectivity.
- ✓
AWS Transit Gateway with attachments for each VPC and the Direct Connect Gateway.
Why this is correct
Transit Gateway enables transitive routing and central management.
- ✗
AWS Site-to-Site VPN connections from on-premises to each VPC.
Why it's wrong here
Does not provide transitive routing; complex to manage.
- ✗
VPC peering between each VPC and the on-premises network.
Why it's wrong here
VPC peering does not support transitive routing.
- ✓
AWS Direct Connect Gateway attached to the Transit Gateway.
Why this is correct
Direct Connect Gateway allows connectivity to multiple VPCs via Transit Gateway.

Variation 1. A company is designing a new hybrid cloud solution that requires low-latency access to on-premises data from AWS. The connection must be highly available and encrypted. The company has multiple VPCs and on-premises locations. Which combination of services meets these requirements?
hard- A.AWS Site-to-Site VPN and VPC Endpoints
- ✓ B.AWS Transit Gateway and AWS Direct Connect with VPN backup
- C.VPC Peering and AWS Site-to-Site VPN
- D.AWS Client VPN and VPC Peering
Why B: AWS Transit Gateway acts as a central hub to interconnect multiple VPCs and on-premises networks, simplifying the hybrid architecture. AWS Direct Connect provides a private, low-latency, and consistent network path, while a Site-to-Site VPN over the Direct Connect link (or as a separate backup) adds encryption and high availability. This combination meets all requirements: low latency (Direct Connect), encryption (VPN), high availability (dual connections or failover), and support for multiple VPCs and on-premises locations (Transit Gateway).
