- A
AWS Global Accelerator endpoints in each VPC.
Why wrong: Global Accelerator is for traffic acceleration, not connectivity.
- B
AWS Transit Gateway with attachments for each VPC and the Direct Connect Gateway.
Transit Gateway enables transitive routing and central management.
- C
AWS Site-to-Site VPN connections from on-premises to each VPC.
Why wrong: Does not provide transitive routing; complex to manage.
- D
VPC peering between each VPC and the on-premises network.
Why wrong: VPC peering does not support transitive routing.
- E
AWS Direct Connect Gateway attached to the Transit Gateway.
Direct Connect Gateway allows connectivity to multiple VPCs via Transit Gateway.

SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. 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 cloud solution that extends its on-premises data center to AWS. The company has a 10 Gbps AWS Direct Connect connection and needs to securely connect multiple VPCs and on-premises networks with transitive routing. The solution must be highly available and use AWS managed services. Which TWO components should the company include in the design? (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
✓
AWS Transit Gateway with attachments for each VPC and the Direct Connect Gateway.
Option B is correct because AWS Transit Gateway provides transitive routing between multiple VPCs and on-premises networks, eliminating the need for complex peering meshes. Option E is correct because attaching a Direct Connect Gateway to the Transit Gateway allows the single 10 Gbps Direct Connect connection to be shared across all attached VPCs, enabling centralized, highly available connectivity.
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 with transitive routing, or assume that Direct Connect alone provides transitive connectivity, but neither VPC peering nor a standalone Direct Connect connection offers the transitive routing required for a multi-VPC hybrid architecture.
Detailed technical explanation
How to think about this question
Under the hood, AWS Transit Gateway uses a hub-and-spoke model where each VPC and the Direct Connect Gateway are attached as separate attachments, and route tables control traffic flow. The Direct Connect Gateway acts as a bridge between the on-premises network (via Direct Connect) and the Transit Gateway, allowing BGP to propagate routes from on-premises into the Transit Gateway route tables. This design supports high availability by using multiple Direct Connect virtual interfaces (VIFs) and Transit Gateway attachments across different Availability Zones.
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.
