Which AWS services or tools can help identify rightsizing opportunities for Amazon EC2 instances? (Choose two.)

AWS Cost Explorer helps identify rightsizing opportunities by providing detailed cost and usage reports. You can analyze your EC2 instance usage patterns over time to see if instances are over-provisioned (running at low utilization) or under-provisioned, allowing you to choose more cost-effective instance types. AWS Compute Optimizer is a dedicated service that analyzes the configuration and utilization metrics of your AWS resources, including EC2 instances, to recommend optimal AWS resources to reduce costs and improve performance. It provides specific rightsizing recommendations, such as changing instance types, based on your actual usage. AWS Billing Conductor is used for custom billing hierarchies and isn't designed for rightsizing recommendations. Amazon CodeGuru is a developer tool for automated code reviews and application profiling, not infrastructure optimization. Amazon SageMaker is a machine learning service for building, training, and deploying models, not for EC2 rightsizing.
