Zorluk: OrtaAWS Trusted Advisor Cost Optimization Checks

An organization has several development environments running in AWS. To reduce monthly expenditures, a SysOps administrator is analyzing AWS Trusted Advisor Cost Optimization recommendations. The administrator wants to identify resources that are either idle or underutilized based on the default criteria of Trusted Advisor checks. Which of the following conditions will cause AWS Trusted Advisor to flag resources as cost optimization opportunities? (Select TWO.)

  1. An Amazon RDS DB instance that has had no database connections for the past 77 consecutive days.Cevap
  2. An Amazon EBS volume that has been unattached or has had less than 1 IOPS1\text{ IOPS} of daily activity for the past 77 consecutive days.Cevap
  3. C
    An Amazon EC2 instance that has had a daily average CPU utilization below 10%10\% and network I/O below 5 MB5\text{ MB} for at least 22 days within a 77-day window.
  4. D
    An Amazon S3 bucket containing objects that have not been accessed for 3030 days and are missing a transition lifecycle rule.
  5. E
    An Elastic Load Balancer that has processed fewer than 100100 requests over the last 1414 days.

Cevap

The options stating that an Amazon RDS DB instance has had no database connections for the past 77 consecutive days, and that an Amazon EBS volume has been unattached or has had less than 1 IOPS1\text{ IOPS} of daily activity for the past 77 consecutive days are correct.
The correct options are the ones stating that an Amazon RDS DB instance has had no database connections for the past 77 consecutive days, and that an Amazon EBS volume has been unattached or has had less than 1 IOPS1\text{ IOPS} of daily activity for the past 77 consecutive days. AWS Trusted Advisor evaluates RDS DB instance connections over a 77-day rolling window to identify idle resources. It also checks EBS volumes over a 77-day rolling window, flagging those that are unattached or have negligible I/O activity (less than 1 IOPS1\text{ IOPS} daily) to help reduce storage costs.

Adım Adım Çözüm

1
Analyze AWS Trusted Advisor Cost Optimization check criteria for Amazon RDS.
Identify that Trusted Advisor monitors active database connections and flags RDS DB instances that have had zero connections for the last 77 days.
This helps determine if the RDS check criteria matches the scenario.
2
Analyze AWS Trusted Advisor Cost Optimization check criteria for Amazon EBS.
Identify that Trusted Advisor monitors volume attachment and daily read/write IOPS, flagging volumes that are unattached or have less than 1 IOPS1\text{ IOPS} per day for the last 77 days.
This helps determine if the EBS check criteria matches the scenario.
3
Evaluate the incorrect options containing EC2 utilization, S3 lifecycle transitions, and load balancer request thresholds.
Identify that the EC2 check requires 44 or more days in the last 1414 days, the ELB check evaluates a 77-day period, and S3 lifecycle rules are not monitored by these specific idle checks.
This rules out the incorrect options based on metrics and evaluation windows.
