SAP-C02 第 69 题
题目
A financial services company in North America plans to release a new online web application to its customers on AWS. The company will launch the application in the us-east-1 Region on Amazon EC2 instances. The application must be highly available and must dynamically scale to meet user traffic. The company also wants to implement a disaster recovery environment for the application in the us-west-1 Region by using active-passive failover. Which solution will meet these requirements?

北美的一家金融服务公司计划在 AWS 上向其客户发布新的在线 Web 应用程序。该公司将在 us-east-1 区域的 Amazon EC2 实例上启动该应用程序。应用程序必须具有高可用性,并且必须动态扩展以满足用户流量。该公司还希望通过使用主动-被动故障转移为 us-west-1 区域中的应用程序实施灾难恢复环境。哪种解决方案可以满足这些要求?
选项
A. Create a VPC in us-east-1 and a VPC in us-west-1. Configure VPC peering. In the us-east-1 VPC, create an Application Load Balancer (ALB) that extends across multiple Availability Zones in both VPCs. Create an Auto Scaling group that deploys the EC2 instances across the multiple Availability Zones in both VPCs. Place the Auto Scaling group behind the ALB.

在 us-east-1 中创建一个 VPC,在 us-west-1 中创建一个 VPC。配置 VPC 对等互连。在 us-east-1 VPC 中,创建一个跨两个 VPC 中的多个可用区扩展的应用程序负载均衡器 (ALB)。创建一个 Auto Scaling 组,用于跨两个 VPC 中的多个可用区部署 EC2 实例。将 Auto Scaling 组放置在 ALB 后面。
B. Create a VPC in us-east-1 and a VPC in us-west-1. In the us-east-1 VPC, create an Application Load Balancer (ALB) that extends across multiple Availability Zones in that VPC. Create an Auto Scaling group that deploys the EC2 instances across the multiple Availability Zones in the us-east-1 VPC. Place the Auto Scaling group behind the ALSet up the same configuration in the us-west-1 VPC. Create an Amazon Route 53 hosted zone. Create separate records for each ALEnable health checks to ensure high availability between Regions.

在 us-east-1 中创建一个 VPC,在 us-west-1 中创建一个 VPC。在 us-east-1 VPC 中,创建一个跨该 VPC 中的多个可用区扩展的应用程序负载均衡器 (ALB)。创建一个 Auto Scaling 组,用于跨 us-east-1 VPC 中的多个可用区部署 EC2 实例。将 Auto Scaling 组放在 AL 后面,在 us-west-1 VPC 中设置相同的配置。创建 Amazon Route 53 托管区域。为每个 ALEnable 运行状况检查创建单独的记录,以确保区域之间的高可用性。
C. Create a VPC in us-east-1 and a VPC in us-west-1. In the us-east-1 VPC, create an Application Load Balancer (ALB) that extends across multiple Availability Zones in that VPC. Create an Auto Scaling group that deploys the EC2 instances across the multiple Availability Zones in the us-east-1 VPPlace the Auto Scaling group behind the ALB. Set up the same configuration in the us-west-1 VPC. Create an Amazon Route 53 hosted zone. Create separate records for each ALB. Enable health checks and configure a failover routing policy for each record.

Create an Auto Scaling group that deploys the EC2 instances across the multiple Availability Zones in both VPCs. Place the Auto Scaling group behind the ALB. Create an Amazon Route 53 hosted zone. Create a record for the ALB.
