Zorluk: KolayHybrid and Multi-Account Network Connectivity Design

A company is designing a hybrid network architecture to connect ten VPCs in the us-east-1 region to an on-premises data center. To reduce administrative overhead, the company wants to avoid establishing individual VPN connections or VPC peering connections between all VPCs and the on-premises environment. Additionally, the design must support communication between the VPCs themselves.

Which two AWS networking components should the solutions architect combine to meet these requirements? (Select TWO.)

  1. AWS Transit Gateway to act as a centralized hub for VPC-to-VPC and hybrid trafficCevap
  2. An AWS Site-to-Site VPN connection attached to the Transit Gateway to route on-premises traffic through the hubCevap
  3. C
    A full mesh of VPC Peering connections between all ten VPCs to enable inter-VPC traffic
  4. D
    A Route 53 Private Hosted Zone associated only with a single transit VPC to handle all routing and DNS resolution

Cevap

AWS Transit Gateway to act as a centralized hub for VPC-to-VPC and hybrid traffic, and an AWS Site-to-Site VPN connection attached to the Transit Gateway to route on-premises traffic through the hub
The correct solution combines AWS Transit Gateway and an AWS Site-to-Site VPN connection attached to the Transit Gateway. AWS Transit Gateway acts as a central cloud router that supports transitive routing, enabling the ten VPCs to communicate with one another and with the hybrid connection. Attaching the Site-to-Site VPN to the Transit Gateway allows all connected VPCs to share the same VPN connection to reach the on-premises data center, which minimizes administrative overhead compared to setting up individual VPN tunnels for each VPC.

Adım Adım Çözüm

1
Analyze the requirements for VPC-to-VPC and VPC-to-on-premises connectivity with minimal administrative overhead.
Identify that a hub-and-spoke architecture is required to avoid the complexity of a full-mesh configuration.
Establishing individual VPNs or peering connections scales poorly and increases management complexity.
2
Select the hub component that supports transitive routing.
AWS Transit Gateway is chosen as the central cloud router.
Transit Gateway allows multiple VPCs and VPNs to attach to it, enabling centralized traffic routing.
3
Establish the hybrid connectivity to the on-premises data center.
An AWS Site-to-Site VPN connection is attached to the Transit Gateway.
This allows all VPCs attached to the Transit Gateway to share the same VPN connection to access the on-premises network, minimizing overhead.

Anahtar Kavram

AWS Transit Gateway acts as a cloud router to simplify network topology by connecting multiple VPCs and hybrid networks through a single hub, eliminating the need for complex mesh configurations.
