- A
Internet Gateway attached to the VPC
Why wrong: Internet Gateway is for internet access, not private connectivity.
- B
Direct Connect Gateway associated with the Transit Gateway
This allows the Direct Connect connection to be propagated to the Transit Gateway.
- C
Direct Connect private virtual interface attached to a Direct Connect Gateway
This provides a dedicated connection without internet.
- D
Site-to-Site VPN connection to the Transit Gateway
Why wrong: VPN uses the internet; the requirement is to avoid the internet.
- E
CloudFront distribution in front of the web application
Why wrong: CloudFront is a CDN and does not provide private connectivity.

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 is using AWS Transit Gateway to connect multiple VPCs and on-premises networks. They have a VPC with a subnet that hosts a web application. They need to ensure that traffic from the on-premises network to the web application does not traverse the internet. Which TWO components are required? (Select TWO.)
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
✓
Direct Connect Gateway associated with the Transit Gateway
Option B is correct because a Direct Connect Gateway associated with the Transit Gateway allows traffic from on-premises networks to reach VPCs attached to the Transit Gateway without traversing the internet. This association enables the Transit Gateway to route traffic between Direct Connect virtual interfaces and VPC attachments using private IP addresses, ensuring the path remains over the AWS private network.
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 a Site-to-Site VPN can provide private connectivity, but the trap here is that VPNs still traverse the public internet (even if encrypted), whereas Direct Connect provides a dedicated private path that avoids internet transit entirely.
Detailed technical explanation
How to think about this question
A Direct Connect Gateway acts as a global transit hub that can be associated with up to three Transit Gateways in different AWS Regions, enabling inter-region private connectivity. The private virtual interface (VIF) terminates on the Direct Connect Gateway, which then propagates routes to the Transit Gateway via BGP, allowing the Transit Gateway to learn on-premises prefixes and route traffic accordingly. This setup supports jumbo frames (MTU 9001) over Direct Connect, which can improve throughput for large data transfers compared to VPN-based solutions.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
