SAP-C02 第 524 题
题目
A company migrated to AWS and uses AWS Business Support. The company wants to monitor the cost-effectiveness of Amazon EC2 instances across AWS accounts. The EC2 instances have tags for department, business unit, and environment. Development EC2 instances have high cost but low utilization. The company needs to detect and stop any underutilized development EC2 instances. Instances are underutilized if they had 10% or less average daily CPU utilization and 5 MB or less network I/O for at least 4 of the past 14 days. Which solution will meet these requirements with the LEAST operational overhead?
中文翻译:
一家公司迁移到 AWS 并使用 AWS 业务支持。该公司希望跨 AWS 账户监控 Amazon EC2 实例的成本效益。 EC2 实例具有部门、业务单位和环境的标签。开发EC2实例成本高但利用率低。该公司需要检测并停止任何未充分利用的开发 EC2 实例。如果实例在过去 14 天内至少有 4 天内平均每日 CPU 利用率为 10% 或更低且网络 I/O 为 5 MB 或更低,则实例未得到充分利用。哪种解决方案能够以最少的运营开销满足这些要求?
选项
A. Configure Amazon CloudWatch dashboards to monitor EC2 instance utilization based on tags for department, business unit, and environment. Create an Amazon EventBridge rule that invokes an AWS Lambda function to stop underutilized development EC2 instances.
中文翻译:
配置 Amazon CloudWatch 仪表板以根据部门、业务部门和环境的标签监控 EC2 实例利用率。创建一个 Amazon EventBridge 规则,调用 AWS Lambda 函数来停止未充分利用的开发 EC2 实例。
B. Configure AWS Systems Manager to track EC2 instance utilization and report underutilized instances to Amazon CloudWatch. Filter the CloudWatch data by tags for department, business unit, and environment. Create an Amazon EventBridge rule that invokes an AWS Lambda function to stop underutilized development EC2 instances.
中文翻译:
配置 AWS Systems Manager 以跟踪 EC2 实例利用率并向 Amazon CloudWatch 报告未充分利用的实例。按部门、业务部门和环境的标签筛选 CloudWatch 数据。创建一个 Amazon EventBridge 规则,调用 AWS Lambda 函数来停止未充分利用的开发 EC2 实例。
C. Create an Amazon EventBridge rule to detect low utilization of EC2 instances reported by AWS Trusted Advisor. Configure the rule to invoke an AWS Lambda function that filters the data by tags for department, business unit, and environment and stops underutilized development EC2 instances.
中文翻译:
创建 Amazon EventBridge 规则来检测 AWS Trusted Advisor 报告的 EC2 实例利用率低的情况。配置规则以调用 AWS Lambda 函数,该函数按部门、业务部门和环境的标签筛选数据,并停止未充分利用的开发 EC2 实例。
D. Create an AWS Lambda function to run daily to retrieve utilization data for all EC2 instances. Save the data to an Amazon DynamoDB table. Create an Amazon QuickSight dashboard that uses the DynamoDB table as a data source to identify and stop underutilized development EC2 instances.
中文翻译:
创建每天运行的 AWS Lambda 函数以检索所有 EC2 实例的利用率数据。将数据保存到 Amazon DynamoDB 表。创建一个 Amazon QuickSight 仪表板,使用 DynamoDB 表作为数据源来识别和停止未充分利用的开发 EC2 实例。
答案
C
解析
正确答案:C 解析: 本题应选择 C。 正确选项: C. 创建 Amazon EventBridge 规则来检测 AWS Trusted Advisor 报告的 EC2 实例利用率低的情况。配置规则以调用 AWS Lambda 函数,该函数按部门、业务部门和环境的标签筛选数据,并停止未充分利用的开发 EC2 实例。 选择理由: 该选项最直接地满足题干中的关键约束。做 SAP-C02 题目时,需要同时对照题干里的限定词,例如最高性能、最低...
