AWS Transit Gateway
AWS Transit Gateway is a network transit hub that connects VPCs, VPN connections, and AWS Direct Connect connections. It supports transitive routing, allowing all attached networks to communicate through a single gateway, which simplifies network architecture.
- B
Amazon Route 53
Why wrong: Amazon Route 53 is a scalable Domain Name System (DNS) web service. It resolves domain names to IP addresses but does not provide network routing between VPCs or on-premises networks.
- C
AWS Direct Connect Gateway
Why wrong: AWS Direct Connect Gateway allows a Direct Connect connection to access VPCs in any AWS Region, but it does not provide transitive routing between those VPCs. For VPC-to-VPC communication, additional components like Transit Gateway or VPC peering are needed.
- D
AWS PrivateLink
Why wrong: AWS PrivateLink provides private connectivity between VPCs and AWS services, or between VPCs and on-premises applications, but it does not offer transitive routing across multiple VPCs or act as a central hub for network traffic.
CLF-C02 Cloud Technology and Services Practice Question
This CLF-C02 practice question tests your understanding of cloud technology and services. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 runs a multi-region application on AWS with separate VPCs in us-east-1 and eu-west-1. The company also has an on-premises data center connected to AWS via AWS Direct Connect. The network team wants to simplify the routing topology so that traffic between all VPCs and the on-premises network flows through a central hub. They need a service that can manage many VPC attachments and provide transitive routing across all connected networks. Which AWS service should the network team use?
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
AWS Transit Gateway is the correct choice because it acts as a central hub that connects multiple VPCs and on-premises networks via a single gateway, enabling transitive routing between all attached networks. It supports many VPC attachments (up to thousands per gateway) and simplifies routing topology by eliminating the need for complex peering or VPN mesh configurations. This directly meets the requirement for a service that manages many VPC attachments and provides transitive routing across all connected networks.
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 Route 53
Why it's wrong here
Amazon Route 53 is a scalable Domain Name System (DNS) web service. It resolves domain names to IP addresses but does not provide network routing between VPCs or on-premises networks.
When this WOULD be correct
A company wants to route traffic to an on-premises data center using a domain name, and needs DNS resolution to return the correct IP address based on the health and location of endpoints. Route 53 would be the correct answer for a DNS-based traffic management scenario.
- ✗
AWS Direct Connect Gateway
Why it's wrong here
AWS Direct Connect Gateway allows a Direct Connect connection to access VPCs in any AWS Region, but it does not provide transitive routing between those VPCs. For VPC-to-VPC communication, additional components like Transit Gateway or VPC peering are needed.
When this WOULD be correct
A company has multiple VPCs in the same or different regions that need to connect to a single on-premises data center via AWS Direct Connect. The requirement is to simplify the connection of multiple VPCs to the Direct Connect link without needing transitive routing between VPCs.
- ✗
AWS PrivateLink
Why it's wrong here
AWS PrivateLink provides private connectivity between VPCs and AWS services, or between VPCs and on-premises applications, but it does not offer transitive routing across multiple VPCs or act as a central hub for network traffic.
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 network transit hub that connects VPCs, VPN connections, and AWS Direct Connect connections. It supports transitive routing, allowing all attached networks to communicate through a single gateway, which simplifies network architecture.
✗Amazon Route 53Wrong answer — click to see why▾
Why this is wrong here
Amazon Route 53 is a DNS service, not a network transit or routing service. It cannot provide transitive routing between VPCs and on-premises networks.
★ When this WOULD be the correct answer
A company wants to route traffic to an on-premises data center using a domain name, and needs DNS resolution to return the correct IP address based on the health and location of endpoints. Route 53 would be the correct answer for a DNS-based traffic management scenario.
Why candidates choose this
Candidates may confuse 'routing' in the context of DNS (routing traffic to endpoints) with network-layer routing, leading them to select Route 53 when the question is about VPC-to-VPC and on-premises connectivity.
✗AWS Direct Connect GatewayWrong answer — click to see why▾
Why this is wrong here
AWS Direct Connect Gateway is used to connect multiple VPCs to a Direct Connect connection, but it does not provide transitive routing between VPCs or between VPCs and on-premises networks across different regions; it only facilitates private connectivity to a single Direct Connect link.
★ When this WOULD be the correct answer
A company has multiple VPCs in the same or different regions that need to connect to a single on-premises data center via AWS Direct Connect. The requirement is to simplify the connection of multiple VPCs to the Direct Connect link without needing transitive routing between VPCs.
Why candidates choose this
Candidates may confuse Direct Connect Gateway with Transit Gateway because both can connect multiple VPCs to on-premises networks, but they overlook that Direct Connect Gateway lacks transitive routing capabilities between attached networks.
✗AWS PrivateLinkWrong answer — click to see why▾
Why this is wrong here
AWS PrivateLink does not provide transitive routing between VPCs or between VPCs and on-premises networks; it only enables private connectivity to specific services or endpoints within a VPC.
★ When this WOULD be the correct answer
A company needs to privately access a third-party SaaS application hosted in another AWS account without using public internet, VPC peering, or VPN. AWS PrivateLink would be the correct service to create a VPC endpoint for that service.
Why candidates choose this
Candidates may confuse PrivateLink's ability to connect VPCs to services with the need for transitive routing, or they may think it can replace a transit gateway for hub-and-spoke topologies.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS Direct Connect Gateway with Transit Gateway, assuming Direct Connect Gateway can provide transitive routing between VPCs, but it only connects Direct Connect circuits to multiple VPCs and does not enable VPC-to-VPC routing or act as a central hub for all network attachments.
Detailed technical explanation
How to think about this question
AWS Transit Gateway uses a hub-and-spoke architecture where each VPC or on-premises network attaches to the gateway via a VPC attachment or VPN attachment, and routing is managed through route tables that can propagate and filter routes. Under the hood, Transit Gateway leverages AWS's internal network infrastructure to forward traffic between attachments without traversing the public internet, supporting protocols like BGP for dynamic route exchange with on-premises networks. In a real-world scenario, a company with dozens of VPCs across multiple regions can use a single Transit Gateway in a central region (e.g., us-east-1) and peer it with another Transit Gateway in eu-west-1 to enable inter-region transitive routing, all while maintaining a simplified routing topology.
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.
