- A
AWS Transit Gateway
AWS Transit Gateway is a central hub that connects VPCs and on-premises networks. It supports hub-and-spoke topology, scales to hundreds of VPCs, and works with Direct Connect and VPNs. This meets the requirement for simplified, scalable connectivity with centralized routing.
- B
Amazon VPC peering
Why wrong: Amazon VPC peering creates a one-to-one connection between two VPCs. To connect many VPCs, you would need a full mesh of peering connections, which does not scale well and increases complexity. It also cannot directly connect to on-premises networks via Direct Connect.
- C
AWS PrivateLink
Why wrong: AWS PrivateLink provides private connectivity to services hosted on AWS by exposing endpoints within a VPC. It is designed for accessing specific services, not for routing traffic between multiple VPCs or connecting to on-premises networks.
- D
AWS Site-to-Site VPN
Why wrong: AWS Site-to-Site VPN connects on-premises networks to a single VPC. While it can be part of a hybrid solution, it does not interconnect multiple VPCs. Managing multiple VPN connections to each VPC does not simplify the architecture.
Quick Answer
The answer is AWS Transit Gateway, which is the correct choice because it acts as a single, scalable network hub that connects multiple VPCs and on-premises networks with centralized routing, eliminating the need for complex, meshed VPC peering connections. By using a centralized routing table, Transit Gateway provides transitive routing across all attached networks, including those connected via AWS Direct Connect, allowing you to scale seamlessly to hundreds of VPCs without the management overhead of individual peering links. On the AWS Certified Cloud Practitioner CLF-C02 exam, this scenario tests your understanding of network connectivity services and the difference between point-to-point VPC peering and hub-and-spoke architectures—a common trap is choosing VPC Peering or Direct Connect alone, but remember that Transit Gateway is the only service that offers transitive routing at scale. A simple memory tip: think of Transit Gateway as a "network roundabout" where all traffic flows through a central hub, unlike peering which is like a direct road between just two locations.
CLF-C02 Cloud Technology and Services Practice Question
This CLF-C02 practice question tests your understanding of cloud technology and services. 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 operates multiple Amazon VPCs across several AWS accounts for different business units. The company also has an on-premises data center connected to AWS via AWS Direct Connect. The network team wants to simplify the connectivity between all VPCs and the on-premises network. Currently, they manage individual VPC peering connections, which is becoming complex as more VPCs are added. They need a single network hub that can scale to connect hundreds of VPCs and the on-premises network, with centralized routing management. Which AWS service should the network team use?

Correct answer & explanation
AWS Transit Gateway
AWS Transit Gateway acts as a single, scalable network hub that connects multiple VPCs and on-premises networks via Direct Connect, using a centralized routing table. This eliminates the need for complex, meshed VPC peering connections and provides transitive routing across all attached networks, which directly addresses the requirement for a hub that scales to hundreds of VPCs.
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
AWS often tests the misconception that VPC peering can be used as a hub-and-spoke solution, but candidates must remember that VPC peering is non-transitive and requires a full mesh, whereas Transit Gateway provides transitive routing and centralized management.
Detailed technical explanation
How to think about this question
AWS Transit Gateway uses a centralized routing table that supports transitive routing between all attached VPCs and VPN/Direct Connect connections, leveraging BGP for dynamic route exchange. Under the hood, each attachment is associated with a route table, and you can create route propagation rules to control traffic flow, enabling segmentation and isolation between business units. In real-world scenarios, a Transit Gateway can handle up to 5,000 attachments per region, making it ideal for large-scale multi-account architectures.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
