[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company’s application is deployed on Amazon EC2 instances and uses AWS Lambda functions for an event-driven architecture. The company uses nonproduction development environments in a different AWS account to test new features before the company deploys the features to production.

The production instances show constant usage because of customers in different time zones. The company uses nonproduction instances only during business hours on weekdays. The company does not use the nonproduction instances on the weekends. The company wants to optimize the costs to run its application on AWS.

Which solution will meet these requirements MOST cost-effectively?

  • A. Use On-Demand Instances for the production instances. Use Dedicated Hosts for the nonproduction instances on weekends only.
  • B. Use Reserved Instances for the production instances and the nonproduction instances. Shut down the nonproduction instances when not in use.
  • C. Use Compute Savings Plans for the production instances. Use On-Demand Instances for the nonproduction instances. Shut down the nonproduction instances when not in use.
  • D. Use Dedicated Hosts for the production instances. Use EC2 Instance Savings Plans for the nonproduction instances.

A Reserved Instance is preferred if you use the reserve capacity for the full duration of the one- or three-year term. You may also find that a Reserved Instance offers cost savings over On-Demand Instances, even if you are only using the instance at half capacity. Reserved Instances also offer guaranteed availability for stop-and-start scenarios. In addition, by utilizing and continuously monitoring Convertible Reserved Instances, you can save more money.

"An Amazon EC2 Dedicated Host is a physical server fully dedicated for your use, so you can help address corporate compliance requirements." https://aws.amazon.com/ec2/dedicated-hosts/ That already eliminates "A" and "D". No need to pay extra since there is no requirement for eligible software licences. B is INCORRECT = no need to use reserved instances for non-prod, since they will only be active during business hours during weekdays.
