SAP-C02 Question #520: Real Exam Question with Answer & Explanation

Question

An entertainment company recently launched a new game. To ensure a good experience for players during the launch period, the company deployed a static quantity of 12 r6g.16xlarge (memory optimized) Amazon EC2 instances behind a Network Load Balancer. The company's operations team used the Amazon CloudWatch agent and a custom metric to include memory utilization in its monitoring strategy. Analysis of the CloudWatch metrics from the launch period showed consumption at about one quarter of the CPU and memory that the company expected. Initial demand for the game has subsided and has become more variable. The company decides to use an Auto Scaling group that monitors the CPU and memory consumption to dynamically scale the instance fleet. A solutions architect needs to configure the Auto Scaling group to meet demand in the most cost- effective way. Which solution will meet these requirements?

Options

• AConfigure the Auto Scaling group to deploy c6g.4xlarge (compute optimized) instances. Configure
• BConfigure the Auto Scaling group to deploy m6g.4xlarge (general purpose) instances. Configure a
• CConfigure the Auto Scaling group to deploy r6g.4xlarge (memory optimized) instances. Configure
• DConfigure the Auto Scaling group to deploy r6g.8xlarge (memory optimized) instances. Configure

Explanation

From the question, app is running on memory-optimized instances (r6g.16xlarge) but only utilizing about one quarter of the CPU and memory. So cost-effective to use smaller instances (r6g.4xlarge), which provide a quarter of r6g.16xlarge instances.
