SAP-C02 第 116 题
题目
A retail company has an on-premises data center in Europe. The company also has a multi-Region AWS presence that includes the eu-west-1 and us-east-1 Regions. The company wants to be able to route network traffic from its on-premises infrastructure into VPCs in either of those Regions. The company also needs to support traffic that is routed directly between VPCs in those Regions. No single points of failure can exist on the network. The company already has created two 1 Gbps AWS Direct Connect connections from its on-premises data center. Each connection goes into a separate Direct Connect location in Europe for high availability. These two locations are named DX-A and DX-B, respectively. Each Region has a single AWS Transit Gateway that is configured to route all inter-VPC traffic within that Region. Which solution will meet these requirements?

一家零售公司在欧洲拥有一个本地数据中心。该公司还拥有多区域 AWS 业务，其中包括 eu-west-1 和 us-east-1 区域。该公司希望能够将网络流量从其本地基础设施路由到这两个区域中的 VPC。该公司还需要支持在这些区域的 VPC 之间直接路由的流量。网络上不能存在单点故障。该公司已经从其本地数据中心创建了两个 1 Gbps AWS Direct Connect 连接。每个连接都会进入欧洲的一个单独的 Direct Connect 位置，以实现高可用性。这两个位置分别命名为 DX-A 和 DX-B。每个区域都有一个 AWS Transit Gateway，配置为路由该区域内的所有 VPC 间流量。哪种解决方案可以满足这些要求？
选项
A. Create a private VIF from the DX-A connection into a Direct Connect gateway. Create a private VIF from the DX-B connection into the same Direct Connect gateway for high availability. Associate both the eu-west-1 and us-east-1 transit gateways with the Direct Connect gateway. Peer the transit gateways with each other to support cross-Region routing.
中文翻译：
创建从 DX-A 连接到 Direct Connect 网关的专用 VIF。创建从 DX-B 连接到同一 Direct Connect 网关的专用 VIF，以实现高可用性。将 eu-west-1 和 us-east-1 中转网关与 Direct Connect 网关关联。将中转网关彼此对等以支持跨区域路由。
B. Create a transit VIF from the DX-A connection into a Direct Connect gateway. Associate the eu-west-1 transit gateway with this Direct Connect gateway. Create a transit VIF from the DX-8 connection into a separate Direct Connect gateway. Associate the us-east-1 transit gateway with this separate Direct Connect gateway. Peer the Direct Connect gateways with each other to support high availability and cross-Region routing.

创建从 DX-A 连接到 Direct Connect 网关的中转 VIF。将 eu-west-1 中转网关与此 Direct Connect 网关关联。创建从 DX-8 连接到单独的 Direct Connect 网关的中转 VIF。将 us-east-1 中转网关与此单独的 Direct Connect 网关关联。将 Direct Connect 网关彼此对等以支持高可用性和跨区域路由。
C. Create a transit VIF from the DX-A connection into a Direct Connect gateway. Create a transit VIF from the DX-B connection into the same Direct Connect gateway for high availability. Associate both the eu-west-1 and us-east-1 transit gateways with this Direct Connect gateway. Configure the Direct Connect gateway to route traffic between the transit gateways.

创建从 DX-A 连接到 Direct Connect 网关的中转 VIF。创建从 DX-B 连接到同一 Direct Connect 网关的中转 VIF，以实现高可用性。将 eu-west-1 和 us-east-1 中转网关与此 Direct Connect 网关关联。配置 Direct Connect 网关以在中转网关之间路由流量。
D. Create a transit VIF from the DX-A connection into a Direct Connect gateway. Create a transit VIF from the DX-B connection into the same Direct Connect gateway for high availability. Associate both the eu-west-1 and us-east-1 transit gateways with this Direct Connect gateway. Peer the transit gateways with each other to support cross-Region routing.
