The answer is to create a transit virtual interface and associate it with a transit gateway. This is the correct approach because a Direct Connect gateway acts as a regional hub, allowing a single dedicated connection to route traffic to multiple VPCs, while a transit virtual interface (VIF) is the only interface type that can connect to a transit gateway, which then enables transitive routing across all attached VPCs in the same region. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this scenario tests your understanding of the Direct Connect gateway and transit gateway architecture, often appearing as a trap where you might mistakenly choose a private VIF—but remember, a private VIF can only connect to a single VPC. The key memory tip is: for multiple VPCs, think “Transit VIF + Transit Gateway = Multi-VPC connectivity,” and never pair a private VIF with a Direct Connect gateway alone, as that still limits you to one VPC.
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 designing a hybrid network using AWS Direct Connect. The company has a single 1 Gbps dedicated connection and wants to connect to multiple VPCs in the same region. Which THREE steps are necessary to achieve this connectivity?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a Direct Connect gateway.
Options A, C, and D are correct because a Direct Connect gateway allows multiple VPCs, and a transit VIF with a transit gateway is the recommended approach. B is not needed. E is incorrect because a private VIF can only connect to one VPC.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company needs to connect multiple VPCs to a common on-premises network through a single AWS Direct Connect connection. Which AWS service should be used to simplify this architecture?
easy
A.AWS VPN CloudHub
✓ B.AWS Transit Gateway
C.VPC peering
D.Virtual Private Gateway (VGW)
Why B: Option D is correct because Transit Gateway allows connecting multiple VPCs and on-premises networks via a single Direct Connect connection using a transit VIF. Option A is wrong because VPC peering is point-to-point and does not scale to many VPCs. Option B is wrong because VPN CloudHub connects VPNs, not Direct Connect. Option C is wrong because VGW is per-VPC.
Variation 2. A company has multiple VPCs that need to communicate with each other. They want to use a hub-and-spoke model with centralized network management. Which AWS service should they use?
medium
A.AWS Direct Connect
B.VPN CloudHub
C.VPC Peering
✓ D.AWS Transit Gateway
Why D: AWS Transit Gateway (D) is the correct choice because it acts as a central hub that interconnects multiple VPCs and on-premises networks using a hub-and-spoke topology. It simplifies network management by providing a single point of connectivity and supports transitive routing between all attached VPCs, which is exactly what the company needs for centralized network management.
Variation 3. A company has multiple VPCs that need to communicate with each other and with an on-premises network via AWS Transit Gateway. Which THREE of the following are valid attachment types for a transit gateway?
medium
✓ A.Direct Connect Gateway
B.Internet Gateway
✓ C.Site-to-Site VPN connection
✓ D.VPC
E.Network Load Balancer
Why A: Transit gateway supports attachments to VPCs, VPN connections, and Direct Connect gateways. Option D is incorrect because an internet gateway is attached to a VPC, not to a transit gateway. Option E is incorrect because a network load balancer is not directly attached to a transit gateway.
