Which of the following actions are examples of rightsizing AWS resources to reduce cloud expenses? (Choose two.)

Rightsizing involves optimizing resource allocation to match actual needs, thereby reducing costs. Choosing Amazon EC2 instance types based on historical utilization patterns directly addresses rightsizing by selecting instances that provide adequate performance without overprovisioning. Similarly, applying Amazon S3 Lifecycle policies to move infrequently accessed objects to lower-cost storage tiers (like S3 Infrequent Access or Glacier) is a classic rightsizing strategy for storage, aligning cost with access frequency. Switching from Amazon RDS to Amazon DynamoDB is a database migration and re-architecture, not rightsizing. Using Multi-AZ deployments for Amazon RDS enhances availability, not cost optimization through rightsizing. Replacing EC2 with Elastic Beanstalk is a change in deployment model, not a direct rightsizing action for existing resources.
