- A
Create a VPN connection between each VPC and a central VPN appliance.
Why wrong: Complex and not scalable.
- B
Establish VPC peering connections in a full mesh and manage routes centrally.
Possible but less scalable than Transit Gateway.
- C
Use Direct Connect to connect VPCs.
Why wrong: Direct Connect is for on-premises.
- D
Use an AWS Transit Gateway with a central VPC as the hub.
Native hub-and-spoke architecture.
- E
Use VPC Gateway Endpoints to connect VPCs.
Why wrong: Endpoints are for AWS services.

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.
Which TWO of the following are valid methods to connect multiple VPCs together in a hub-and-spoke topology while maintaining centralized control? (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
✓
Establish VPC peering connections in a full mesh and manage routes centrally.
Option B is correct because VPC peering connections can be arranged in a full mesh, and by centrally managing route tables (e.g., using a centralized route management tool or a central VPC with route propagation), you can enforce a hub-and-spoke routing pattern. Option D is correct because AWS Transit Gateway inherently supports hub-and-spoke topologies by attaching multiple VPCs to a single gateway, which acts as the hub, and allows centralized control over routing and security policies.
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 VPC peering as inherently non-hub-and-spoke, but the question allows for a full mesh of peering connections with centralized route management, which technically satisfies the requirement, while Direct Connect and Gateway Endpoints are frequently misapplied as VPC-to-VPC connectivity solutions.
Detailed technical explanation
How to think about this question
AWS Transit Gateway uses a hub-and-spoke model where each VPC attachment is a separate routing domain, and you can centrally control inter-VPC traffic through route tables and propagation. VPC peering, while point-to-point, can be orchestrated into a hub-and-spoke pattern by using a central VPC as a route reflector and managing routes via AWS Resource Access Manager or custom scripts, but it does not scale as well as Transit Gateway due to the transitive routing limitation (peering is non-transitive). In real-world scenarios, Transit Gateway is preferred for large-scale hub-and-spoke deployments because it supports thousands of VPCs and integrates with Direct Connect and VPN for hybrid connectivity.
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.
