Show answer and explanation
Correct answers: A, B, D
Explanation
Identifying and remediating underutilized or unused resources requires a combination of tools that provide cost optimization and usage analysis capabilities. AWS Trusted Advisor highlights underutilized EC2 instances and EBS volumes, AWS Compute Optimizer provides detailed rightsizing recommendations, and AWS Cost Explorer enables cost trend analysis to identify potential inefficiencies. Together, these services are effective for addressing underutilized or unused resources, while CloudWatch and AWS Shield are not directly applicable for this use case.
- A. Correct.
AWS Trusted Advisor provides recommendations for cost optimization, including identifying underutilized resources like EC2 instances and EBS volumes. It is effective for spotting unused resources.
- B. Correct.
AWS Compute Optimizer analyzes the usage patterns of EC2 instances and other resources and provides rightsizing recommendations, helping to reduce costs by suggesting optimal configurations.
- C. Incorrect.
Amazon CloudWatch is primarily used for monitoring and alerting. While it can provide metrics and alarms, it does not directly identify or terminate unused resources.
- D. Correct.
AWS Cost Explorer helps analyze spending and usage patterns, allowing you to identify trends and underutilized resources. It is a key tool for cost analysis and optimization.
- E. Incorrect.
AWS Shield is primarily used for DDoS protection and security. It does not provide any functionality for optimizing or identifying underutilized compute resources.
