Question 70 of 100 | ← Chapter 1

A SysOps administrator needs to track the costs of data transfer between AWS Regions. The SysOps administrator must implement a solution to send alerts to an email distribution list when transfer costs reach 75% of a specific threshold. What should the SysOps administrator do to meet these requirements?

• A. Create an AWS Cost and Usage Report. Analyze the results in Amazon Athena. Configure an alarm to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic when costs reach 75% of the threshold. Subscribe the email distribution list to the topic.
• B. Create an Amazon CloudWatch billing alarm to detect when costs reach 75% of the threshold. Configure the alarm to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the email distribution list to the topic.
• C. Use AWS Budgets to create a cost budget for data transfer costs. Set an alert at 75% of the budgeted amount. Configure the budget to send a notification to the email distribution list when costs reach 75% of the threshold. ✓
• D. Set up a VPC flow log. Set up a subscription filter to an AWS Lambda function to analyze data transfer. Configure the Lambda function to send a notification to the email distribution list when costs reach 75% of the threshold.

Correct Answer: C. Use AWS Budgets to create a cost budget for data transfer costs. Set an alert at 75% of the budgeted amount. Configure the budget to send a notification to the email distribution list when costs reach 75% of the threshold.

Explanation

AWS Budgets允许用户根据成本或使用情况创建预算，并设置自定义的警报阈值。根据AWS官方文档，AWS Budgets支持针对特定服务的成本跟踪，包括数据转移费用。用户可以为数据传输成本创建独立预算，配置警报触发条件（如75%阈值），并直接通过电子邮件发送通知。选项C通过AWS Budgets的警报机制直接满足需求，无需额外处理数据或使用其他服务组合。选项A需要手动分析报告，选项B无法针对特定服务费用，选项D监控的是网络流量而非成本数据。
