- A
Create a Transit Gateway in the central networking account
A central Transit Gateway is created in the networking account.
- B
Use AWS Resource Access Manager (RAM) to share the Transit Gateway with other accounts
RAM allows sharing the Transit Gateway with other accounts.
- C
Create a separate Transit Gateway in each account and peer them together
Why wrong: Using a single shared Transit Gateway is simpler and more scalable.
- D
Create a Transit Gateway route table and associate VPC attachments
Route tables control traffic between attachments.
- E
Create a VPC peering connection between each VPC and the Transit Gateway
Why wrong: VPCs attach to the Transit Gateway, not via VPC peering.

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 multi-account AWS environment using AWS Transit Gateway. They want to centralize network management and ensure that VPCs in different accounts can communicate. Which THREE steps are required to achieve this? (Select THREE.)
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
✓
Create a Transit Gateway in the central networking account
Option A is correct because the Transit Gateway must be created in a central networking account to serve as the hub for all VPC traffic. This centralizes routing and simplifies network management across the multi-account environment.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Create a VPC peering connection between each VPC and the Transit Gateway
Why it's wrong here
VPCs attach to the Transit Gateway, not via VPC peering.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates might think each account needs its own Transit Gateway (Option C) or that VPC peering is required to connect to the Transit Gateway (Option E), when in fact a single shared Transit Gateway with VPC attachments is the correct approach.
Detailed technical explanation
How to think about this question
AWS Transit Gateway uses a hub-and-spoke model where VPC attachments are associated with route tables to control traffic flow. When sharing the Transit Gateway via AWS Resource Access Manager (RAM), the Transit Gateway remains in the owner account, and participant accounts can create attachments without needing to manage the Transit Gateway itself. This design supports transitive routing between all attached VPCs, which is not possible with VPC peering alone.
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.
