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 use AWS Direct Connect to establish a dedicated network connection from their on-premises data center to AWS. They need to connect to a VPC in the us-east-1 region. Which of the following is a required step in the setup process?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a private virtual interface and attach it to a Virtual Private Gateway.
To establish a Direct Connect connection to a VPC, you must create a private virtual interface (VIF) and attach it to a Virtual Private Gateway (VGW) that is attached to the VPC. The private VIF carries traffic over the dedicated connection and uses BGP to exchange routes between the on-premises network and the VPC via the VGW. This is the core requirement for routing traffic from the Direct Connect link into a VPC.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Attach a Transit Gateway to the VPC.
Why it's wrong here
Transit Gateway is not required for a single VPC connection.
✗
Configure CloudFront to route traffic through the Direct Connect.
Why it's wrong here
CloudFront is a CDN service, not used for Direct Connect routing.
Create a private virtual interface and attach it to a Virtual Private Gateway.
Why this is correct
This is the standard procedure for Direct Connect private VIF.

Common exam traps
Common exam trap: answer the scenario, not the keyword
AWS often tests the misconception that a Transit Gateway is mandatory for Direct Connect, but the correct requirement is a Virtual Private Gateway attached to the VPC, not a Transit Gateway.
Detailed technical explanation
How to think about this question
A private virtual interface uses 802.1Q VLAN tagging and BGP to establish Layer 3 connectivity between the customer router and the AWS Direct Connect endpoint. The Virtual Private Gateway acts as a BGP peer and routes traffic from the VIF into the VPC using the VPC route tables. In real-world scenarios, you must ensure the VIF's VLAN ID and BGP ASN are unique and that the VGW's route propagation is enabled to automatically advertise VPC CIDRs to the on-premises network.

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.
