What task should you include in the runbook?

You have an Azure subscription that contains an Azure virtual machine named VM1. VM1 runs a financial reporting app named App1 that does not support multiple active instances.

At the end of each month, CPU usage for VM1 peaks when App1 runs.

You need to create a scheduled runbook to increase the processor performance of VM1 at the end of each month.

What task should you include in the runbook?
A . Add the Azure Performance Diagnostics agent to VM1.
B . Modify the VM size property of VM1.
C . Add VM1 to a scale set.
D . Increase the vCPU quota for the subscription.
E . Add a Desired State Configuration (DSC) extension to VM1.

Answer: B

Explanation:

To create a scheduled runbook to increase the processor performance of VM1 at the end of each month, you need to modify the VM size property of VM1. This will allow you to scale up the VM to a larger size that has more CPU cores and memory. You can use Azure Automation to create a PowerShell runbook that changes the VM size using the Set-AzVM cmdlet. You can then schedule the runbook to run at the end of each month using the Azure portal or Azure PowerShell.
