- A
AWS Site-to-Site VPN
Why wrong: Site-to-Site VPN encrypts traffic but still routes it over the public internet — it doesn't provide the consistent latency and dedicated bandwidth of Direct Connect.
- B
Amazon CloudFront
Why wrong: CloudFront is a CDN for content delivery — it doesn't provide dedicated private connectivity from on-premises to AWS.
- C
AWS Direct Connect
Direct Connect provides dedicated private network connections to AWS, bypassing the internet for consistent performance, lower latency, and reduced data transfer costs.
- D
AWS Transit Gateway
Why wrong: Transit Gateway routes traffic between VPCs and VPN connections — it's a network hub, not the physical connectivity solution from on-premises to AWS.

CLF-C02 Cloud Technology and Services Practice Question
This CLF-C02 practice question tests your understanding of cloud technology and services. 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.
Which AWS service provides a private connection from an on-premises network to AWS that bypasses the public internet and provides consistent network performance?
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 answer because it provides a dedicated, private network connection from an on-premises data center to AWS, completely bypassing the public internet. This ensures consistent network performance, lower latency, and higher bandwidth, as the connection is established through a standard 1 Gbps or 10 Gbps Ethernet fiber-optic cable linked to an AWS Direct Connect location.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS Site-to-Site VPN (which also connects on-premises to AWS) with a private connection, but VPN still traverses the public internet and cannot guarantee consistent performance, whereas Direct Connect is the only option that physically bypasses the internet.
Detailed technical explanation
How to think about this question
AWS Direct Connect operates over a dedicated Ethernet VLAN using 802.1Q tagging, with the customer or partner router establishing a BGP session (using eBGP) to exchange routes with the AWS router. This eliminates the overhead of IPsec encryption and the variability of internet routing, making it ideal for latency-sensitive workloads like real-time data replication or large-scale data migrations. A real-world scenario is a financial institution transferring terabytes of transaction logs daily to Amazon S3, where consistent throughput and low jitter are critical for compliance.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
