CLF-C02 Cloud Technology and Services Practice Question
Which AWS service provides a private, dedicated network connection between an organization's on-premises environment and AWS through a colocation facility or telecommunications partner?
⚠ Common exam trap
Many candidates confuse AWS Direct Connect with AWS VPN solutions (like VPN CloudHub) because both can connect on-premises networks, but only Direct Connect offers a private, dedicated physical link that avoids the public internet entirely.

Correct answer & explanation
✓
AWS Direct Connect
AWS Direct Connect is the correct answer because it provides a private, dedicated network connection from an on-premises data center to AWS, bypassing the public internet. This connection is established through a colocation facility or a telecommunications partner using industry-standard 802.1Q VLANs, offering consistent latency and higher bandwidth than internet-based VPNs.

AWS VPN CloudHub
Why it's wrong here
AWS VPN CloudHub is a hub-and-spoke architecture that uses multiple IPSec VPN tunnels over the public internet to connect remote sites to an AWS VPN gateway. It is useful for managing inter-site communication among branch offices, but each tunnel's performance depends on internet variables like latency, packet loss, and jitter. Because it is not a private, dedicated circuit, it cannot guarantee the consistent, low-latency performance or predictable data transfer costs that a dedicated connection would provide.

AWS Direct Connect
Why this is correct
AWS Direct Connect provides a dedicated, private network connection from your on-premises data center to AWS, with supported bandwidths of 1 Gbps, 10 Gbps, or 100 Gbps. By bypassing the public internet, it delivers lower latency, more consistent network performance, and reduced data transfer costs for high-volume hybrid workloads. This makes it the correct answer for scenarios requiring reliable, dedicated connectivity between a corporate environment and AWS.

Amazon CloudFront Private Content
Why it's wrong here
Amazon CloudFront Private Content is a content delivery network (CDN) feature that restricts access to origin assets using signed URLs or signed cookies. While this protects and controls who can view your content, it operates at the application layer to accelerate and secure HTTP(S) delivery at edge locations. It does not create a dedicated network path between your on-premises infrastructure and your VPC, so it cannot satisfy a requirement for private, high-bandwidth, consistent network connectivity.
- ✗
AWS PrivateLink
Why it's wrong here
AWS PrivateLink enables private connectivity between virtual private clouds (VPCs), AWS services, and on-premises networks via interface endpoints. However, its primary use case is allowing you to access AWS services or customer services hosted in another VPC without traversing the public internet. It does not provide a dedicated physical or logical connection from an on-premises data center to AWS; instead, it relies on existing VPC networking, so it is not a standalone hybrid connectivity solution.
