Difficulty: EasyAWS Trusted Advisor Cost Optimization Checks

A SysOps administrator is reviewing recommendations to optimize AWS infrastructure spending. The administrator wants to identify underutilized resources using AWS Trusted Advisor checks.

Which two of the following findings are reported by AWS Trusted Advisor cost optimization checks? (Select TWO.)

  1. Unassociated Elastic IP AddressesAnswer
  2. Idle Load BalancersAnswer
  3. C
    Detailed CloudWatch monitoring enabled on EC2 instances
  4. D
    Amazon S3 lifecycle rules that attempt to transition objects to a warmer storage class
  5. E
    Amazon S3 buckets containing untagged resources that have not been activated in the billing console

Answer

Unassociated Elastic IP Addresses and Idle Load Balancers
AWS Trusted Advisor includes specific cost optimization checks to identify resources that are running but not being utilized effectively. The checks for 'Unassociated Elastic IP Addresses' and 'Idle Load Balancers' directly identify unused network resources that incur ongoing hourly charges, allowing administrators to release or delete them to reduce costs.

Step-by-Step Solution

1
Review the purpose of AWS Trusted Advisor cost optimization checks, which focus on identifying unused, underutilized, or idle active resources that incur fees.
Identify that checks such as idle load balancers and unassociated Elastic IP addresses are primary sources of unnecessary spend flagged by Trusted Advisor.
This establishes the scope of Trusted Advisor cost checks.
2
Differentiate between actual Trusted Advisor active resource cost checks and general configuration mistakes (such as lifecycle policies, tagging errors, or standard vs. detailed monitoring configurations).
Recognize that invalid transitions, untagged resources, and CloudWatch detailed monitoring settings are not checked by Trusted Advisor's cost module.
This eliminates the distractors.
