SOA-C02 Question 303
Select 3An organization has noticed that their monthly AWS bill is higher than expected. Upon investigation, they suspect there are underutilized or unused resources in the account. Which combination of AWS services and tools should the SysOps Administrator use to identify and remediate these resources?
- A
Use AWS Trusted Advisor to check for underutilized EC2 instances and idle load balancers.
- B
Use AWS Compute Optimizer to review recommendations for rightsizing EC2 instances.
- C
Use AWS Cost Explorer to analyze cost trends and unused resources over time.
- D
Use Amazon CloudWatch to terminate unused EC2 instances automatically.
- E
Use AWS Config to create a rule to detect unused resources and delete them automatically.
Show answer and explanation
Correct answers: A, B, C
Explanation
To identify and remediate underutilized or unused resources, AWS provides tools like Trusted Advisor, Compute Optimizer, and Cost Explorer. Trusted Advisor highlights resource inefficiencies, Compute Optimizer provides instance rightsizing recommendations, and Cost Explorer helps analyze cost and usage trends. While CloudWatch and Config are powerful monitoring tools, they do not natively handle automated resource termination or deletion without additional configurations.
- A. Correct.
Correct: AWS Trusted Advisor provides checks for identifying underutilized resources such as EC2 instances, idle load balancers, and unused EBS volumes.
- B. Correct.
Correct: AWS Compute Optimizer offers recommendations for optimizing EC2 instances based on usage patterns, helping to reduce costs.
- C. Correct.
Correct: AWS Cost Explorer allows you to analyze cost trends, identify unused or underutilized resources, and make informed decisions for cost optimization.
- D. Incorrect.
Incorrect: Amazon CloudWatch is primarily used for monitoring and alerting, but it does not directly terminate unused resources. Automated termination would require additional logic, such as Lambda functions.
- E. Incorrect.
Incorrect: AWS Config can identify non-compliance with rules, but it does not delete resources automatically. Automated resource deletion would require custom workflows or Lambda integrations.
