   An administrator reviews the monthly cloud bill and notices that a large portion of the cost comes from a storage account that is rarely accessed. The administrator wants to reduce storage costs without affecting the application's ability to retrieve the data when needed. What should the administrator do?

   • AIncrease the redundancy of the storage account to protect against data loss.
   • BMove the data to a lower-cost storage tier, such as cool or archive, based on access frequency.
   • CMove the storage account to a different region with lower storage prices.
   • DDelete the storage account and recreate it when needed.

   A company runs a development environment that is only used during business hours. The VMs are left running 24/7, resulting in high costs. The administrator wants to automate cost savings without manual intervention. What should the administrator do?

   • AMove the VMs to a different availability zone to take advantage of lower pricing.
   • BReduce the VM sizes to the smallest available instance type.
   • CCreate a schedule that automatically deallocates the VMs after business hours and starts them before the next business day.
   • DManually shut down the VMs at the end of each day and start them in the morning.

   An administrator is analyzing the performance of a cloud application. The monitoring data shows that CPU utilization is consistently below 10% for 90% of the time, but spikes to 100% for a few minutes each day. The application is not latency-sensitive and can tolerate brief delays. The administrator wants to reduce costs. What should the administrator do?

   • AMove the application to a serverless function to eliminate the VM cost.
   • BIncrease the VM size to handle the spikes more efficiently.
   • CKeep the current VM size and enable autoscaling to add a second VM when CPU exceeds 90%.
   • DRight-size the VM to a smaller instance and rely on the occasional spike being handled by the smaller instance's burst capacity.
