Zorluk: ZorAWS Trusted Advisor Cost Optimization Checks

A company is reviewing its AWS Trusted Advisor Cost Optimization recommendations to reduce monthly expenditures. The SysOps administrator identifies multiple findings in the dashboard:

- Several Amazon Elastic Block Store (Amazon EBS) volumes are flagged under the `Underutilized Amazon EBS Volumes` check because they have been unattached for more than 1414 days.
- Multiple Amazon Relational Database Service (Amazon RDS) DB instances are flagged under the `Amazon RDS Idle DB Instances` check because they have had 00 active database connections for the last 77 days.

The administrator wants to configure an automated solution to remediate these specific findings with minimal administrative effort.

Which of the following remediation workflows should the administrator implement? (Select TWO.)

  1. Configure an Amazon EventBridge rule that filters for `aws.trustedadvisor` events with the check name `Underutilized Amazon EBS Volumes` and status `WARN` or `ERROR`, and target an AWS Systems Manager (SSM) Automation document to snapshot and delete the flagged volumes.Cevap
  2. Configure an Amazon EventBridge rule that filters for `aws.trustedadvisor` events with the check name `Amazon RDS Idle DB Instances` and status `WARN` or `ERROR`, and target an AWS Systems Manager (SSM) Automation document to stop the flagged DB instances.Cevap
  3. C
    Configure a custom AWS Config rule that monitors the RDS `DatabaseConnections` metric, and configure an automatic remediation target to transition the idle RDS DB instances to Multi-AZ deployments.
  4. D
    Enable Detailed Monitoring in Amazon CloudWatch for all EBS volumes, and configure a CloudWatch alarm that triggers an AWS Budgets action to automatically delete the volumes when average read/write IOPS falls below 11 IOPS.
  5. E
    Configure an Amazon EventBridge rule that detects the Trusted Advisor check results, and target an AWS Billing policy to automatically purchase an EC2 Instance Savings Plan to cover the idle RDS instances.

Cevap

Configure an Amazon EventBridge rule targeting an AWS Systems Manager (SSM) Automation document to snapshot and delete the flagged underutilized EBS volumes, and configure an EventBridge rule targeting an SSM Automation document to stop the flagged idle RDS DB instances.
Remediation of underutilized EBS volumes and idle RDS instances can be automated by creating Amazon EventBridge rules filtering for AWS Trusted Advisor findings and triggering targeted AWS Systems Manager (SSM) Automation documents. The rule for underutilized EBS volumes correctly targets an SSM document to snapshot and delete the unattached volumes to stop storage costs. The rule for idle RDS DB instances targets an SSM document to stop the database instances, saving compute costs.

Adım Adım Çözüm

1
Analyze the event source for Trusted Advisor findings.
Identify that AWS Trusted Advisor publishes event notifications to Amazon EventBridge under the source `aws.trustedadvisor` with specific check names in the event details.
Establishing the source of the automation trigger is necessary to filter for cost optimization alerts.
2
Select the correct remediation target and action for unattached EBS volumes.
Use an Amazon EventBridge rule matching `Underutilized Amazon EBS Volumes` to trigger an AWS Systems Manager (SSM) Automation document that takes a snapshot and deletes the volumes.
This removes the unattached volumes, stopping storage costs while preserving data if needed.
3
Select the correct remediation target and action for idle RDS DB instances.
Use an Amazon EventBridge rule matching `Amazon RDS Idle DB Instances` to trigger an SSM Automation document that stops the RDS instances.
Stopping the database instances halts the compute charges immediately while keeping the data intact.

Anahtar Kavram

AWS Trusted Advisor integrates with Amazon EventBridge to publish check status notifications. You can build automated, event-driven remediation workflows by routing these events to AWS Systems Manager Automation documents or AWS Lambda functions.
