Assume that you are accessing a Windows Server $2022$ machine which is the domain controller of cyber.suny.edu domain. Write PowerShell commands for the followings:

a$.$ Create an organization unit named Students.

New$-$ADOrganizationalUnit $-$Name "Students"

b$.$ Create a security group named Students within the Students organization unit.

New$-$ADGroup $-$Name $$Students$-$Groupscope Global $-$Path $$OU$=$Students,DC$=$cyber.suny,DC$=$edu$$

Is the $\text{'}$DC$=\text{'}$ part correct? How do you write the command with a sub domain?
