AWS Transit Gateway for Simplified VPC and On-Premises Connectivity

CLF-C02 By islever Editorial Last updated

Identify AWS network services.

Short answer

B AWS Transit Gateway serves as a cloud router to connect multiple VPCs and on-premises networks, simplifying peering relationships.

Question

A company is connecting multiple VPCs and on-premises networks. The company needs to use an AWS service as a cloud router to simplify peering relationships. Which AWS service can the company use to meet this requirement?
  1. AWS Direct Connect
  2. AWS Transit Gateway Correct Answer
  3. Amazon Connect
  4. Amazon Route 53

Key Takeaways

The question tests knowledge of network connectivity services, with the common trap being confusion between direct dedicated connections (Direct Connect) and hub-and-spoke routing (Transit Gateway).

This page explains how AWS Transit Gateway acts as a cloud router to simplify connections between multiple VPCs and on-premises networks, reducing the complexity of peering relationships.

Common mistake: Users often select AWS Direct Connect because it connects on-premises to AWS, but they miss the requirement to connect 'multiple VPCs' and 'simplify peering', which is the specific domain of Transit Gateway.

Expert Analysis

Why the Answer Is Correct

AWS Transit Gateway is a fully managed service that acts as a cloud router, allowing you to connect thousands of VPCs and on-premises networks through a central hub. This architecture significantly simplifies network management by eliminating the need for complex mesh-like VPC peering connections, making option B the correct choice.

Why the Other Options Are Wrong

AWS Direct Connect (A) provides dedicated network connections from on-premises to AWS but does not inherently simplify VPC-to-VPC peering or act as a central router for multiple VPCs. Amazon Connect (C) is a cloud-based contact center service, unrelated to networking. Amazon Route 53 (D) is a scalable DNS web service, not a network router for VPC interconnectivity.

Community Comment Notes

Community consensus strongly supports option B, with users noting that Transit Gateway eliminates the need for complex peering relationships. One commenter highlighted that it allows connecting multiple VPCs and on-premises networks through a central hub, while another confirmed it acts as a cloud router. There was minimal dissent, with only one user incorrectly suggesting Direct Connect.

Exam Strategy

When questions mention 'simplifying peering' or 'connecting multiple VPCs', immediately think of Transit Gateway. If the focus is solely on 'dedicated connection from on-premises', consider Direct Connect, but remember it doesn't solve the VPC peering complexity issue.

Frequently Asked Questions

Why is Direct Connect not the answer?

Direct Connect connects on-premises to AWS but does not simplify VPC-to-VPC peering. Transit Gateway is needed for multi-VPC hub-and-spoke architecture.

Does Transit Gateway replace VPC Peering entirely?

It doesn't replace peering technically, but it simplifies the topology by acting as a central hub, avoiding the need for full-mesh peering connections.

    AWS Direct Connect makes it easy to establish a dedicated connection from an on-premises network to one or more VPCs. AWS Direct Connect can reduce network costs, increase bandwidth throughput, and provide a more consistent network experience than internet-based connections.
