You have deployed a three-tier web application in a VPC with a CIDR block of 10.0.0.0/28. You initially deploy two web servers, two application servers, two database servers and one NAT instance for a total of seven EC2 instances. The web, application and database servers are deployed across two Availability Zones (AZs). You also deploy an ELB in front of the two web servers, and use Route 53 for DNS. Web traffic gradually increases in the first few days following the deployment, so you attempt to double the number of instances in each tier of the application to handle the new load. Unfortunately some of these new instances fail to launch. Which of the following could be the root cause? (Choose 2 answers)
您已在 CIDR 块为 10.0.0.0/28 的 VPC 中部署了三层 Web 应用程序。您最初部署两台 Web 服务器、两台应用程序服务器、两台数据库服务器和一个 NAT 实例，总共七个 EC2 实例。 Web、应用程序和数据库服务器跨两个可用区 (AZ) 部署。您还在两个 Web 服务器前面部署 ELB，并使用 Route 53 作为 DNS。部署后的最初几天，Web 流量逐渐增加，因此您尝试将应用程序每一层中的实例数量加倍以处理新负载。不幸的是，其中一些新实例无法启动。以下哪一项可能是根本原因？ （选择 2 个答案）
AWS reserves the first and the last private IP address in each subnet's CIDR block so you do not have enough addresses left to launch all of the new EC2 instances.
AWS 保留每个子网 CIDR 块中的第一个和最后一个私有 IP 地址，因此您没有足够的地址来启动所有新的 EC2 实例。

您的 VPC 的互联网网关 (IGW) 已进行扩展，添加了更多实例来应对流量高峰，减少了新实例启动时可用的私有 IP 地址的数量。
The ELB has scaled-up, adding more instances to handle the traffic spike, reducing the number of available private IP addresses for new instance launches.
ELB 已进行了扩展，添加了更多实例来应对流量高峰，减少了新实例启动时可用的私有 IP 地址的数量。
AWS reserves one IP address in each subnet's CIDR block for Route 53 so you do not have enough addresses left to launch all of the new EC2 instances.
AWS 在每个子网的 CIDR 块中为 Route 53 保留一个 IP 地址，因此您没有足够的地址来启动所有新的 EC2 实例。

One of the criteria for a new deployment is that the customer wants to use AWS Storage Gateway. However you are not sure whether you should use gateway-cached volumes or gateway-stored volumes or even what the differences are. Which statement below best describes those differences?
新部署的标准之一是客户想要使用 AWS Storage Gateway。但是，您不确定是否应该使用网关缓存卷或网关存储卷，甚至不确定它们之间的区别是什么。以下哪项陈述最能描述这些差异？
Gateway-cached lets you store your data in Amazon Simple Storage Service (Amazon S3) and retain a copy of frequently accessed data subsets locally. Gateway-stored enables you to configure your on-premises gateway to store all your data locally and then asynchronously back up point-in-time snapshots of this data to Amazon S3.
网关缓存可让您将数据存储在 Amazon Simple Storage Service (Amazon S3) 中，并在本地保留经常访问的数据子集的副本。网关存储使您能够将本地网关配置为在本地存储所有数据，然后将该数据的时间点快照异步备份到 Amazon S3。
Gateway-cached is free whilst gateway-stored is not.
网关缓存是免费的，而网关存储则不是。
Gateway-cached is up to 10 times faster than gateway-stored.
网关缓存的速度比网关存储的速度快 10 倍。
Gateway-stored lets you store your data in Amazon Simple Storage Service (Amazon S3) and retain a copy of frequently accessed data subsets locally.
