- 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.
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?

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
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.

Related concept
Read the scenario before looking for a memorised answer.
- ✗
Amazon VPC peering
Why it's wrong here
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.
When this WOULD be correct
When a company needs to connect a small number of VPCs (e.g., 2-5) with simple, direct connectivity and does not require centralized routing or integration with on-premises networks. The question would specify a limited number of VPCs and no need for hub-and-spoke architecture.
- ✗
AWS PrivateLink
Why it's wrong here
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.
When this WOULD be correct
A company needs to expose a service privately from one VPC to multiple consumer VPCs without VPC peering or transit gateway, ensuring traffic does not traverse the public internet. PrivateLink would be the correct answer.
- ✗
AWS Site-to-Site VPN
Why it's wrong here
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.
When this WOULD be correct
A company needs to connect a single VPC to an on-premises data center over the internet with encrypted tunnels, and does not require inter-VPC connectivity or a hub-and-spoke architecture.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CLF-C02 exam frequently reuses these exact scenarios with slightly different constraints.
✓AWS Transit GatewayCorrect answer▾
Why this is correct
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.
✗Amazon VPC peeringWrong answer — click to see why▾
Why this is wrong here
VPC peering requires managing individual connections between each pair of VPCs, which does not scale to hundreds of VPCs and lacks centralized routing management. It also does not natively integrate with on-premises networks via Direct Connect.
★ When this WOULD be the correct answer
When a company needs to connect a small number of VPCs (e.g., 2-5) with simple, direct connectivity and does not require centralized routing or integration with on-premises networks. The question would specify a limited number of VPCs and no need for hub-and-spoke architecture.
Why candidates choose this
Candidates may think VPC peering is the default way to connect VPCs and overlook its scalability limitations, especially when the question mentions 'simplify connectivity' without explicitly stating the need for a hub.
✗AWS PrivateLinkWrong answer — click to see why▾
Why this is wrong here
AWS PrivateLink is used for private connectivity between VPCs and services, not for routing traffic between multiple VPCs or to on-premises networks. It does not provide a hub-and-spoke architecture or centralized routing management.
★ When this WOULD be the correct answer
A company needs to expose a service privately from one VPC to multiple consumer VPCs without VPC peering or transit gateway, ensuring traffic does not traverse the public internet. PrivateLink would be the correct answer.
Why candidates choose this
Candidates may confuse PrivateLink's ability to connect VPCs privately with the need for a network hub, overlooking that PrivateLink only supports point-to-point service connections, not full mesh or hub-and-spoke routing.
✗AWS Site-to-Site VPNWrong answer — click to see why▾
Why this is wrong here
AWS Site-to-Site VPN connects individual VPCs to on-premises networks but does not provide a centralized hub for inter-VPC connectivity or simplify peering complexity across multiple VPCs and accounts.
★ When this WOULD be the correct answer
A company needs to connect a single VPC to an on-premises data center over the internet with encrypted tunnels, and does not require inter-VPC connectivity or a hub-and-spoke architecture.
Why candidates choose this
Candidates may confuse Site-to-Site VPN with Transit Gateway because both can connect on-premises networks, but Site-to-Site VPN lacks the centralized routing and multi-VPC aggregation capabilities needed for this scenario.

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.
