A company launches several Amazon EC2 instances in the AWS Cloud. The company needs to determine whether the Amazon EC2 instances are the appropriate size and type.
Which AWS services will provide this information? (Select TWO.)
A
AWS Auto Scaling
B
AWS Compute Optimizer
C
AWS Control Tower
D
AWS Trusted Advisor
E
AWS X-Ray
Explanation:
AWS Compute Optimizer analyzes the configuration and resource utilization of your EC2 instances and provides recommendations for optimal instance types and sizes based on historical usage patterns. It helps identify rightsizing opportunities to improve performance and reduce costs.
AWS Trusted Advisor provides real-time guidance to help provision your resources following AWS best practices. It includes checks for cost optimization, performance, security, and fault tolerance. Trusted Advisor can identify underutilized EC2 instances and recommend appropriate instance types.
Why not the other options:
AWS Auto Scaling: Automatically adjusts capacity to maintain steady performance at the lowest possible cost, but doesn't provide specific recommendations about instance sizing
AWS Control Tower: Provides governance and multi-account management, not instance optimization
AWS X-Ray: Helps analyze and debug distributed applications, not for instance sizing recommendations
