   A company is decommissioning a set of VMs that were used for a short-term project. The project is complete, and the VMs are no longer needed. What is the correct order of steps in the decommissioning process?

   • AFirst, identify all resources associated with the project (VMs, disks, IPs, etc.), then delete them in a dependency-aware order.
   • BDelete the VMs, then remove any associated resources like disks and network interfaces.
   • CPower off the VMs and leave them for a week to ensure they are not needed before deleting them.
   • DJust delete the VMs, as the cloud provider will automatically clean up all other resources.

   A company runs a stateless web application on a group of VMs. The application experiences sudden, unpredictable spikes in traffic. The company wants to ensure that the application can handle these spikes without manual intervention. Which scaling approach is most appropriate?

   • AA scheduled scaling policy that adds VMs at specific times of the day.
   • BA manual scaling process where an administrator adds VMs when they notice the traffic increasing.
   • CA dynamic scaling policy that adds VMs when CPU utilization or request count exceeds a defined threshold.
   • DA scaling policy that only scales down, removing VMs when traffic is low.

   A company runs a batch processing job that currently uses a single virtual machine with 8 vCPUs and 32 GB of RAM. The job takes 4 hours to complete and is run once a day. The company wants to reduce the time the job takes to finish. What is the most direct way to achieve this using cloud resource scaling?

   • ADecommission the current VM and create a new one with the same specifications but in a different availability zone.
   • BIncrease the VM's vCPU count and RAM to a larger size.
   • CMove the job to a smaller VM with fewer resources to force better code optimization.
   • DConfigure an autoscaling policy to add more VMs when CPU usage exceeds 80%.
