The correct answer is 'Key vault + access policy'. To ensure that the administrative password is not stored in plain text in the Azure Resource Manager (ARM) template, you should use Azure Key Vault to securely store the password. An access policy should be created to control access to the Key Vault. This way, the password can be referenced securely without being exposed in the template. This has been confirmed by the highly-voted answers and relevant documentation.
