A cloud administrator is upgrading a cloud environment and needs to update the automation script to use a new feature from the cloud provider. After executing the script, the deployment fails. Which of the following is the MOST likely cause?
Answer(s): A
The cloud administrator may need to modify the script to ensure that it is compatible with the new APIs and can successfully use the new feature.Location changes, account permissions, and network failures can also cause deployment failures, but they are less likely to be the cause in this scenario, as these issues typically have a broader impact on the entire cloud environment, not just a single deployment.
A systems administrator has been asked to restore a VM from backup without changing the current VM's operating state. Which of the following restoration methods would BEST fit this scenario?
Answer(s): D
Given In-Place VM restoration is an Azure feature, I'm going with "D". Yes, technically, an alternate location restoration would not affect the state of the VM in questions, but "D" is the most logical answer. CompTIA, I'm sure, wants to make sure you're aware of this cloud capability.

Due to a policy change, a few of a customer's application VMs have been migrated to synchronously replicated storage. The customer now reports that performance is lower. The systems administrator checks the resource usage and discovers CPU utilization is at 60% and available memory is at 30%. Which of the following is the MOST likely cause?
Answer(s): C
Application is running in VM. VM was moved. Storage profile should be transparent to the application and its compatibility, but overall storage behavior adds complexity, so latency. Synchronity means waiting for all storage parties to finish a task. Wait = Latency.Example: Move VM from single SDD to HDD-RAID-1. App will work, but write slower.This caught my attention: "... a FEW of a customer's application VMs have been migrated ...". Does this change anything?
A systems administrator wants to ensure two VMs remain together on the same host. Which of the following must be set up to enable this functionality?
