Explanation:
To optimize and appropriately size Amazon EC2 instances based on CPU, memory, and network metrics, the solutions architect needs to both configure comprehensive monitoring and leverage optimization tools. Option C is correct because installing the Amazon CloudWatch agent and configuring memory metric collection will provide the necessary detailed metrics on memory, which is not collected by default. Option D is also correct because enabling AWS Compute Optimizer provides insights and recommendations to optimize the EC2 instances. While options A, B, and E are related to cost optimization and support, they do not specifically address the requirement to optimize based on detailed metrics as effectively as options C and D.
