Question 9 of 75 | ← Chapter 2

Q159. A solutions architect wants to cost-optimize and appropriately size Amazon EC2 instances in a single AWS account. The solutions architect wants to ensure that the instances are optimized based on CPU, memory, and network metricsWhich combination of steps should the solutions architect take to meet these requirements? (Select TWO.)

• A. Purchase AWS Business Support or AWS Enterprise Support for the account
• B. Turn on AWS Trusted Advisor and review any "Low Utilization Amazon EC2 Instances" recommendations
• C. Install the Amazon CloudWatch agent and configure memory metric collection on the EC2 instances ✓
• D. Configure AWS Compute Optimizer in the AWS account to receive findings and optimization recommendations ✓
• E. Create an EC2 Instance Savings Plan for the AWS Regions, instance families, and operating systems of interest

Correct Answer: C. Install the Amazon CloudWatch agent and configure memory metric collection on the EC2 instances, D. Configure AWS Compute Optimizer in the AWS account to receive findings and optimization recommendations

Explanation

To cost-optimize and appropriately size Amazon EC2 instances based on CPU, memory, and network metrics, the solutions architect should take the following steps: C. Install the Amazon CloudWatch agent and configure memory metric collection on the EC2 instances. The CloudWatch agent enables the collection and monitoring of metrics, logs, and events from EC2 instances. By configuring memory metric collection, the solutions architect can gather memory utilization data for optimization purposes. D. Configure AWS Compute Optimizer in the AWS account to receive findings and optimization recommendations. Compute Optimizer analyzes the resource utilization of EC2 instances and provides recommendations for suitable instance types, sizes, and purchasing options based on CPU, memory, and network metrics. By configuring Compute Optimizer, the solutions architect can receive optimization recommendations specific to their EC2 instances.
