You have an Azure subscription that contains 100 virtual machines. You regularly create and delete virtual machines.
You need to identify unattached disks that can be deleted. What should you do?
Correct Answer:A
You can find unused disks in the Azure Storage Explorer console.Once you drill down to the Blob containers under a storage account, you can see the lease state of the residing VHD (the lease state determines if the VHD is being used by any resource) and the VM to which it is leased out. If you find that the lease state and the VM fields are blank, it means that the VHD in question is unused. The screenshot below shows two active VHDs being used by VMs as data and OS disks. The name of the VM and lease state are shown in the "VM Name" and "Lease State" columns, respectively.

You have an Azure subscription that contains a virtual network named VNET1 in the East US 2 region. You have the following resources in an Azure Resource Manager template.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
Solution:
Box 1: Yes
Box 2: Yes
VM1 is in Zone1, while VM2 is on Zone2.
Box 3: No

You have an Azure virtual machine named VM1 that runs Windows Server 2019.
You save VM1 as a template named Template1 to the Azure Resource Manager library. You plan to deploy a virtual machine named VM2 from Template1.
What can you configure during the deployment of VM2?
Correct Answer:D
When deploying a virtual machine from a template, you must specify: 
the Resource Group name and location for the VM
the administrator username and password an unique DNS name for the public IP

You create a virtual machine scale set named Scale1. Scale1 is configured as shown in the following exhibit.
Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic.
Solution:
As cooling period and scale in and scale out durations are not displayed in the graphical view, so we need to consider the default values as below for these settings.
Cool down (minutes) : The amount of time to wait before the rule is applied again so that the autoscale actions have time to take effect. Default is 5 minutes.
Duration : The amount of time monitored before the metric and threshold values are compared. Default is 10 minutes.
Box 1: 4 virtual machines
The Autoscale scale out rule increases the number of VMs by 2 if the CPU threshold is 80% or higher for more than or equals to 10 mins due to default duration for scale in and out is 10 minutes. Since CPU utilization at 85% only lasts for 6 mins , it does not trigger the rules.
Hence no of virtual machines will be same as the initial value which is 4. Box 2: 4 virtual machines
The Autoscale scale in rule decreases the number of VMs by 4 if the CPU threshold is 30% or lower for more than or equal to 10 mins. due to default duration for scale in and out is 10 minutes . Since CPU utilization at 30% only lasts for 6 mins , it does not trigger the rules. Hence after first 6 mins instance count will be same as initial count as 4. After that CPU utilization reached to 50% for 6 mins , which again would not trigger the scale in rule. Therefore no of virtual machines will be same as the initial value which is 4.
