该解决方案架构师应该使用哪种架构来确保最大的可用性？

A

创建一个自动扩展组，在两个区域的每个区域使用三个实例。

B

修改自动扩展组，在两个可用区的每个区使用三个实例。

C

创建一个自动扩展模板，可以用来在另一个区域快速创建更多的实例。

D

在轮流配置中改变亚马逊EC2实例前面的ALB，以平衡到网络层的流量。

单选题
The web application of a business makes use of many Linux Amazon EC2 instances and data is stored on Amazon Elastic Block Store (Amazon EBS) volumes. The organization is searching for a solution that will boost the application's resilience in the event of a failure and will offer storage that adheres to the atomicity, consistency, isolation, and durability requirements (ACID).
What actions should a solutions architect take to ensure that these criteria are met?

单选题

A solutions architect is developing a web application that will be hosted on Amazon EC2 instances and managed by an Application Load Balancer (ALB). The organization places a high premium on the application's resilience to hostile internet activities and assaults, as well as its protection against newly discovered vulnerabilities and exposures.
What recommendations should the solutions architect make?

单选题

A solutions architect is developing a solution that will allow users to browse a collection of photos and make requests for customized images. Parameters for image customisation will be included in each request made to an AWS API Gateway API. The personalized picture will be created on demand, and consumers will get a link to see or download it. The solution must be very user-friendly in terms of viewing and modifying photos.

Which approach is the MOST cost-effective in meeting these requirements?

一个解决方案的架构师正在开发一个解决方案，该方案将允许用户浏览照片集，并提出定制图片的请求。图片定制的参数将包括在向AWS API网关API提出的每个请求中。个性化的图片将按需创建，消费者将得到一个链接来查看或下载它。该解决方案在查看和修改照片方面必须非常方便用户。

在满足这些要求方面，哪种方法的成本效益最高？

A

使用亚马逊EC2实例，将原始图像处理成所要求的定制。在Amazon S3中存储原始图像和操作过的图像。在EC2实例的前面配置一个弹性负载平衡器。

B

使用AWS Lambda将原始图像处理成所要求的定制。在Amazon S3中存储原始图像和操作过的图像。配置一个以S3桶为原点的Amazon CloudFront分发。

C

使用AWS Lambda对原始图像进行操作，以达到要求的定制。将原始图像存储在Amazon S3中，将处理后的图像存储在Amazon DynamoDB中。在亚马逊EC2实例前配置一个弹性负载平衡器。

D

使用Amazon EC2实例将原始图像处理成所要求的定制。在Amazon S3中存储原始图像，在Amazon DynamoDB中存储处理后的图像。配置一个以S3桶为原点的Amazon CloudFront分布。

单选题

A company runs an internal browser-based application. The application runs on Amazon EC2 instances behind an Application Load Balancer. The instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones. The Auto Scaling group scales up to 20 instances during work hours, but scales down to

2 instances overnight. Staff are complaining that the application is very slow when the day begins, although it runs well by mid-morning.

How should the scaling be changed to address the staff complaints and keep costs to a minimum?

一家公司运行一个基于浏览器的内部应用程序。该应用在应用负载平衡器后面的亚马逊EC2实例上运行。这些实例在一个亚马逊EC2自动扩展组中运行，跨越多个可用区。自动扩展组在工作时间内可扩展到20个实例，但在夜间可扩展到 2个实例过夜。工作人员抱怨说，当一天开始的时候，应用程序非常慢，尽管到了上午的时候运行良好。

应该如何改变扩展方式以解决员工的抱怨，并将成本保持在最低水平？

A

实施一个预定的行动，在办公室开放前不久将期望的容量设置为20。

B

实施一个在较低的CPU阈值上触发的阶梯式扩展动作，并减少冷却期。

C

实施一个在较低的CPU阈值上触发的目标跟踪动作，并减少冷却期。

D

实施一个预定动作，在办公室开放前不久将最小和最大容量设置为20。
