- A
Create Transit Gateway peering attachments between the Transit Gateways in each Region.
Peering attachments enable inter-Region connectivity.
- B
Create VPN attachments between each Transit Gateway and the inspection VPC.
Why wrong: VPN attachments are not required; peering attachments are used.
- C
Use VPC peering connections between VPCs in different Regions.
Why wrong: VPC peering does not scale for many VPCs.
- D
Route traffic through a central inspection VPC in one Region using Transit Gateway route tables.
Central inspection can be done via route tables.
- E
Disable cross-Region peering on the Transit Gateway.
Why wrong: Cross-Region peering is needed.

ANS-C01 Network Design Practice Question
This ANS-C01 practice question tests your understanding of network design. 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 connect multiple VPCs in different AWS Regions using AWS Transit Gateway. The company requires full mesh connectivity with centralized inspection of inter-Region traffic. Which TWO actions should the company take? (Choose 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
✓
Create Transit Gateway peering attachments between the Transit Gateways in each Region.
Option A is correct because AWS Transit Gateway supports inter-Region peering attachments, which allow you to connect Transit Gateways in different Regions and route traffic between them using the AWS global network. Option D is correct because you can centralize traffic inspection by routing inter-Region traffic through a dedicated inspection VPC attached to one Transit Gateway, using separate route tables to force traffic through that VPC before forwarding it to the destination Region.
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 trap here is that candidates often confuse Transit Gateway peering with VPC peering, assuming VPC peering can provide transitive routing across multiple VPCs, or they mistakenly think VPN attachments are required for centralized inspection instead of using route tables and attachments.
Detailed technical explanation
How to think about this question
Transit Gateway inter-Region peering uses the AWS global network backbone, providing higher bandwidth and lower latency than internet-based VPNs. The centralized inspection model relies on Transit Gateway route tables with blackhole routes or specific entries to force traffic through a security appliance (e.g., firewall) in an inspection VPC, which then forwards the traffic back to the Transit Gateway for delivery to the peered Region. This design avoids the complexity of managing multiple VPN tunnels and allows for consistent security policy enforcement across Regions.
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.
