ANS-C01 Network Implementation Practice Question
This ANS-C01 practice question tests your understanding of network implementation. 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 establish a dedicated, private connection between their on-premises data center and AWS. They require consistent, low-latency performance and support for multiple VLANs. Which AWS service should they use?
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 network connection from on-premises to AWS, bypassing the public internet to deliver consistent, low-latency performance. It supports multiple VLANs via 802.1Q tagging over a single physical connection, enabling segmentation of traffic (e.g., for private VIFs, public VIFs, and transit VIFs). This meets the requirement for a private, high-performance link with VLAN support.
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 ANS-C01 exam often tests the misconception that Transit Gateway provides the dedicated connection itself, when in fact it is a logical routing construct that requires a physical or virtual underlay (Direct Connect or VPN) to reach on-premises.
Detailed technical explanation
How to think about this question
AWS Direct Connect uses 802.1Q VLAN tagging to support multiple virtual interfaces (VIFs) over a single physical circuit: a private VIF for VPC access, a public VIF for AWS public services, and a transit VIF for use with Transit Gateway. The connection is established through a cross-connect at a Direct Connect location, and the underlying physical link is typically a 1 Gbps or 10 Gbps Ethernet fiber, providing consistent latency as low as 1-5 ms depending on proximity. In real-world scenarios, enterprises often combine Direct Connect with a backup VPN for redundancy, but the primary requirement for dedicated, low-latency, multi-VLAN connectivity mandates Direct Connect.
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.
