This ANS-C01 practice question tests your understanding of network design. 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 company wants to connect its on-premises data center to AWS using a dedicated, private network connection. Which AWS service should be used to establish a 1 Gbps dedicated connection?
AWS Direct Connect
Direct Connect provides a dedicated private connection.
AWS Transit Gateway
Why wrong: Transit Gateway is a hub for VPCs and VPN, not a dedicated connection.
VPC Peering
Why wrong: VPC Peering connects VPCs, not on-premises.
AWS Site-to-Site VPN
Why wrong: VPN uses public internet, not dedicated.
Answer choices
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 service for establishing a dedicated, private network connection from an on-premises data center to AWS. It provides a 1 Gbps (or higher) physical Ethernet link that bypasses the public internet, delivering consistent network performance and reduced bandwidth costs for high-volume data transfer.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
AWS Direct Connect
Why this is correct
Direct Connect provides a dedicated private connection.

AWS Transit Gateway
VPC Peering
Why it's wrong here
VPC Peering connects VPCs, not on-premises.
AWS Site-to-Site VPN
Why it's wrong here
VPN uses public internet, not dedicated.
Common exam traps
AWS often tests the misconception that a VPN can provide a dedicated private connection, but VPNs traverse the public internet and lack the physical isolation and consistent latency of Direct Connect.
Detailed technical explanation
AWS Direct Connect uses IEEE 802.1Q VLANs to segregate traffic across a single physical connection, supporting multiple virtual interfaces (VIFs) for public and private connectivity. The 1 Gbps speed is typically delivered over single-mode fiber using 1000BASE-LX optics, and the connection is established through an AWS Direct Connect location (colocation facility) where the customer's router is cross-connected to an AWS router. In real-world scenarios, enterprises often combine Direct Connect with a VPN as a backup for high availability.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
