ANS-C01 Network Design Practice Question
A company is designing a hybrid network architecture that connects multiple VPCs in different AWS regions to an on-premises data center. The company wants to minimize the number of VPN tunnels and reduce management overhead. Which AWS service should be used to simplify this design?
⚠ Common exam trap
Test-takers frequently confuse VPC peering as a viable option for on-premises connectivity, not realizing that VPC peering only works between VPCs and cannot extend to an on-premises network, leading them to overlook the centralized hub-and-spoke model of Transit Gateway.
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 VPN attachments
AWS Transit Gateway with VPN attachments is correct because it acts as a central hub that connects multiple VPCs across different AWS regions and an on-premises data center through a single VPN connection. This minimizes the number of VPN tunnels by eliminating the need for individual VPN connections between each VPC and the on-premises network, and reduces management overhead through a single point of configuration and routing.
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 with VPN attachments
Why this is correct
Transit Gateway provides a central hub that can connect multiple VPCs and on-premises networks via VPN, reducing the number of connections and simplifying management.
- ✗
AWS Direct Connect with multiple virtual interfaces
Why it's wrong here
Direct Connect provides a private connection to AWS but does not automatically connect multiple VPCs; additional routing is needed.
- ✗
AWS VPN CloudHub
Why it's wrong here
VPN CloudHub connects multiple customer gateways, but it does not natively connect VPCs; it is designed for branch offices.
- ✗
VPC peering between each VPC and the on-premises network
Why it's wrong here
VPC peering does not support transitive routing and requires many connections, increasing complexity.
