AZ-104 Certification Practice Question #175

Question

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?

Accepted Answer

To increase the processor performance of a single virtual machine (VM1), you must scale it up (vertical scaling) by resizing it to a size with more vCPUs. This is accomplished by modifying the VM size property of VM1. Horizontal scaling (Option C - Virtual Machine Scale Sets) cannot be used because the application (App1) does not support multiple active instances. Desired State Configuration (Option E) is used to manage OS-level settings, not VM size hardware properties.
