SAP-C02 Design for New Solutions Practice Question
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?
⚠ Common exam trap
Candidates often assume a single VPN or Direct Connect alone is sufficient, but the question requires both low latency (Direct Connect) and encryption (VPN) across multiple VPCs and on-premises sites, which only Transit Gateway with Direct Connect and VPN backup fully satisfies.

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 and AWS Direct Connect with VPN backup
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).
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 Site-to-Site VPN and VPC Endpoints
Why it's wrong here
VPC endpoints connect privately to AWS services within a VPC; they do not link on-premises networks to AWS. Hybrid connectivity with encryption and redundancy needs AWS Site-to-Site VPN paired with AWS Transit Gateway or Direct Connect. Endpoints suit private access to S3 or DynamoDB from inside AWS.
- ✓
AWS Transit Gateway and AWS Direct Connect with VPN backup
Why this is correct
Transit Gateway provides a hub-and-spoke model for multiple VPCs and on-premises networks. Direct Connect offers dedicated low-latency connections with encryption, and VPN provides a backup.
- ✗
VPC Peering and AWS Site-to-Site VPN
Why it's wrong here
VPC peering only interconnects VPCs, so it cannot reach on-premises locations at all; the Site-to-Site VPN alone terminates at a single virtual private gateway, giving no multi-location redundancy. Site-to-Site VPN suits a single encrypted tunnel between one on-premises site and one VPC, which is why pairing it with peering is tempting here.
- ✗
AWS Client VPN and VPC Peering
Why it's wrong here
AWS Client VPN terminates remote-user sessions, not site-to-site links between on-premises networks and multiple VPCs, so it cannot provide the required hybrid connectivity. It is tempting because it encrypts traffic and integrates with Microsoft Entra ID for user authentication, making it the right choice when individual remote workers need access to VPC resources.
