Question
A cloud administrator is provisioning infrastructure to run an application with the following requirements:
- Ten midsize instances need to run as a cluster most of the day.
- Sixteen midsize instances are required during peak hours.
- Costs must be kept low.
- The instances must be deployed in an IaaS model.
- The application has no tolerance for service disruptions.
Which of the following steps should the cloud architect take to host the application?
Options
- AReserve 16 instances but turn off the unused instances outside of peak hours.
- BUse ten pay-as-you-go instances and add six spot instances during peak hours.
- CDeploy reserved instances for normal operation and add pay-as-you-go instances during peak
- DConfigure the workload to use spot instances with scheduled scaling for normal operation,

Explanation
This solution provides a cost-effective and highly available approach to meet the application’s Reserved instances are a good fit for the ten midsize instances that run most of the day, as they are typically offered at a discounted rate and are guaranteed. During peak hours, pay-as-you-go instances can be added to handle the additional six instances required. This ensures scalability without committing to additional reserved capacity for off-peak times, which helps in reducing costs.
