Zorluk: ZorAWS Cost Explorer and Cost Anomaly Detection

A SysOps administrator needs to implement a cost-monitoring solution for a multi-account organization. The company recently adopted a tagging policy requiring all project resources to carry a Project tag. The administrator has the following requirements:
1. Detect anomalous spend associated with individual projects using machine learning and send alerts to an existing Amazon SNS topic.
2. Analyze daily cost trends and forecast future spending for the next 3 months grouped by the Project tag using AWS Cost Explorer.

Which combination of actions must the administrator take to meet these requirements? (Select TWO.)

  1. Activate the Project tag as a cost allocation tag in the AWS Billing and Cost Management console.Cevap
  2. Create a cost monitor in AWS Cost Anomaly Detection using the Resource tags monitor type with the Project tag key, and create an alert subscription pointing to the Amazon SNS topic.Cevap
  3. C
    Create a cost monitor in AWS Cost Anomaly Detection using the Linked accounts monitor type, and use Amazon EventBridge to route anomaly events to the Amazon SNS topic based on the Project tag value.
  4. D
    Configure an AWS Budget with a daily cost filter for the Project tag, and define an action to publish alerts to the Amazon SNS topic when the budget threshold is exceeded.
  5. E
    Configure AWS Cost Explorer to enable daily granularity, and create a custom CloudWatch metric filter for the Project tag to feed cost data to CloudWatch alarms.

Cevap

Activate the Project tag as a cost allocation tag in the Billing console, and create a Resource tags cost monitor in AWS Cost Anomaly Detection with an alert subscription pointing to the Amazon SNS topic.
To monitor and forecast costs based on a specific tag, the tag must first be activated as a cost allocation tag in the AWS Billing and Cost Management console. Once activated, the tag key becomes available as a dimension in AWS Cost Explorer and AWS Cost Anomaly Detection. To detect anomalous spend on tagged resources using machine learning, a Resource tags monitor must be created in AWS Cost Anomaly Detection with the specified tag key. An alert subscription linked to this monitor is then used to send notifications to the target Amazon SNS topic.

Adım Adım Çözüm

1
Activate the cost allocation tag.
The Project tag becomes available as a dimension in AWS Cost Explorer and AWS Cost Anomaly Detection.
Before user-defined tags can be used in billing tools, they must be explicitly activated in the AWS Billing and Cost Management console.
2
Create the Cost Anomaly Detection monitor.
A monitor is created using the Resource tags monitor type, configured with the Project tag key.
This tells AWS Cost Anomaly Detection to apply machine learning models to track cost anomalies segmented by the different values of the Project tag.
3
Configure the alert subscription.
An alert subscription is linked to the tag monitor, specifying the target Amazon SNS topic ARN.
This establishes the delivery pathway so that any detected anomaly automatically generates a notification to the automation system.
4
Run daily forecasting in Cost Explorer.
Historical daily trends are analyzed and future spending is forecasted for up to 3 months using the activated tag filter.
Cost Explorer supports daily granularity forecasting for up to 3 months when filtering by active cost allocation tags.
