ANS-C01 Network Design Practice Question
A company is designing a hybrid network architecture that requires a dedicated, private, and consistent connection between its on-premises data center and AWS. The connection must support multiple VLANs and provide a service-level agreement (SLA) of 99.99% availability. Which AWS service should be used to meet these requirements?
⚠ Common exam trap
AWS often tests the misconception that AWS Transit Gateway itself provides the dedicated connection, but it is only a logical aggregation point and requires Direct Connect or VPN as the underlying transport to meet the physical connectivity and SLA requirements.
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 Direct Connect
AWS Direct Connect is the correct choice because it provides a dedicated, private, and consistent network connection from an on-premises data center to AWS, bypassing the public internet. It supports multiple VLANs via 802.1Q tagging over a single physical connection, and offers a 99.99% service-level agreement (SLA) when configured with redundant connections at separate Direct Connect locations.

AWS Direct Connect
Why this is correct

AWS Client VPN
Why it's wrong here
Incorrect; AWS Client VPN is for remote client access, not for connecting data centers.
