Which action should a SysOps administrator take to meet these requirements?
Analyze the AWS Cost and Usage Report by using Amazon Athena to identify cost savings.
Create an AWS Budgets alert to alarm when account spend reaches 80% of the budget.
Purchase Reserved Instances through the Amazon EC2 console.
Use AWS Compute Optimizer and take action on the provided recommendations.
Explanations:
Amazon Athena can analyze AWS Cost and Usage Reports, but it does not directly help reduce costs. It is more for reporting and insights rather than actionable savings strategies.
While AWS Budgets can alert you when the spend reaches a threshold, it does not reduce costs. It only provides notifications, but no direct mechanism for cost optimization.
Purchasing Reserved Instances may reduce EC2 costs, but this is a long-term commitment and may not be the most efficient option in terms of cost savings for fluctuating workloads.
AWS Compute Optimizer provides recommendations for EC2 and Lambda optimizations. Following these recommendations can lead to significant cost savings by right-sizing instances and functions.
I evaluate that the answer is:
Use AWS Compute Optimizer and take action on the provided recommendations.
I guess:
Use AWS Compute Optimizer and take action on the provided recommendations.
