You manage a cloud service on two instances. The service name is Service1 and the role name is
ServiceRole1. Service1 has performance issues during heavy traffic periods. You need to increase
the existing deployment of Service1 to three instances. Which Power Shell cmdlet should you use?

A.
PS C:\\>Set-AzureService -ServiceName “Service1” -Label “ServiceRole1′ -Description “Instance count=3”

B.
PS C:\\>Set-AzureRole -ServiceName “Service1” -Slot “Production” -RoleName “ServiceRole1” -Count 3

C.
PS C:\\>Add-AzureWebRole -Name ‘ServiceRole1″ -Instances 3

D.
PS C:\\>$instancecount = New-Object Hashtable$settings[‘INSTANCECOUNT=3]
PS C:\\>Set-AzureWebsite -AppSettings $instancecount ServiceRole1

Explanation:
The Set-AzureRole cmdlet sets the number of instances of a specified role to run in an Azure
deployment. Example:
This command sets the “MyTestRole3” role running in production on the “MySvc1” service to three
instances.
Windows PowerShell
C:\\PS>Set-AzureRole -ServiceName “MySvc1” -Slot “Production” -Role
