Suggested solution to the issue

UserClass does not need to be mandatory. It is not required in the cmdlet.

The DSC configuration that is used to reproduce the issue (as detailed as possible)

dsc_resource 'OptionDef120' do
    resource :xDhcpServerOptionDefinition
    module_name 'xDhcpServer'
    property :Ensure, 'Present'
    property :Name, 'UCSipServer'
    property :OptionID, 120
    property :Type, 'BinaryData'
    property :Description, 'Sip Server Fqdn'
    property :VendorClass, ''
    property :AddressFamily, 'IPv4'
  end

  dsc_resource 'OptionValue120' do
    resource :DhcpServerOptionValue
    module_name 'xDhcpServer'
    property :Ensure, 'Present'
    property :OptionID, 120
    property :Value, ['000963696F2D7563706C31056F73756164036F73750365647500']
    property :VendorClass, ''
    property :AddressFamily, 'IPv4'
  end

Followed by:

  dsc_resource 'OptionValue120' do
    resource :DhcpServerOptionValue
    module_name 'xDhcpServer'
    property :Ensure, 'Present'
    property :OptionID, 120
    property :Value, ['000963696F2D7563706C31056F73756164036F73750365647500']
    property :VendorClass, ''
    property :UserClass, ''
    property :AddressFamily, 'IPv4'
  end

I think you need to have UserClass = '' in the configuration because the parameter is a Key so that you are not able to add the configuration twice. 🤔

Let me know if that does not work.
