Exam AZ-104 topic 4 question 51 discussion

Correct Answer: B Here we need to modify the size of the VM to increase the number of vCPU's assigned to the VM. This can be included as a task in the runbook. The VM size property can be modified by a runbook that is triggered by metrics, but you can schedule it monthly. C: Scheduled vertical scaling could be a solution, but then you don't need a scheduled runbook and it states that it does not support multiple active instances. Scale Set is not a n option. E: DSC is only useful to keep the resources on a VM (OS, File shares, etc.) in a consistent state, not to change VM properties.

not correct. Answer is B. Scale up the VM using Automation virtual scale set runbooks which trigger a webhook

Bcz it does not support multiple active instances.

it´s B

Why not add vm1 to scale set because scale sets are designed for applications that can run multiple instances simultaneously, allowing for automatic scaling based on demand. However, your financial reporting app (App1) does not support multiple active instances. Therefore, adding VM1 to a scale set would not be effective in this case. Why not DSC, Because DSC is useful for maintaining consistent configurations, it does not directly address the need to increase processor performance during peak usage periods.

B is right

This question was in exam 15/01/24

Desired State Configuration (DSC) extension can be used to configure and manage the desired state of a virtual machine (VM) in Azure. DSC allows you to define the configuration of a machine in a declarative way, and it can be used to automate tasks such as adjusting the processor performance.

Answer B

Correct Answer: C

Can anyone explain why the Desired State Configuration (DSC) extension to VM1 is selected as answer, because i don't see any relevant information increase the capacity of VM B: is most voted answer, but resizing the VM, we have to stop the VM

Correct answer: C Azure Virtual Machine Scale Sets let you create and manage a group of load balanced VMs. The number of VM instances can automatically increase or decrease in response to demand or a defined schedule. Scale sets provide the following key benefits: https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/overview

B. Modify the VM size property of VM1. By modifying the VM size, you can choose a higher-tier virtual machine that offers more CPU resources, which can help handle the increased CPU usage during peak times. This allows you to scale up the VM's processing power temporarily to meet the demands of the financial reporting app (App1) at the end of each month.

i think the question is asking after you change the VM size.....how do you ensure after reboot, all the service are running. Hence, DSC come into the picture.

B. Modify the VM size property of VM1.
