Topic 1 Question 61
A company has a stateful, long-running workload on a single xlarge general purpose Amazon EC2 On-Demand Instance Metrics show that the service is always using 80% of its available memory and 40% of its available CPU. A SysOps administrator must reduce the cost of the service without negatively affecting performance. Which change in instance type will meet these requirements?
Change to one large compute optimized On-Demand Instance.
Change to one large memory optimized On-Demand Instance.
Change to one xlarge general purpose Spot Instance.
Change to two large general purpose On-Demand Instances.

For me its C. You can reduce teh cost using a spot instance. Here more about spot instance https://www.amazonaws.cn/en/ec2/spot-instances/faqs/

B. CPU utilisation is rather low for using an xlarge instance, so a memory optimized large instance is a cheaper option that should meet the workload requirements.
