Updates a virtual network link to the specified Private DNS zone.

@param resourceGroupName The name of the resource group.
@param privateZoneName The name of the Private DNS zone (without a terminating dot).
@param virtualNetworkLinkName The name of the virtual network link.
@param parameters Parameters supplied to the Update operation.
@param ifMatch The ETag of the virtual network link to the Private DNS zone. Omit this value to always overwrite the current virtual network link. Specify the last-seen ETag value to prevent accidentally overwriting any concurrent changes.
@throws IllegalArgumentException thrown if parameters fail the validation
@return the observable for the request
