A team is currently creating resource manager templates for building virtual machines on Azure. They have to use the Azure Key Vault service for storing the virtual machine account password. A Key Vault has been created and secrets created in the service. 
The following parameter file is being created to recover the secret from the Key Vault. 

Which of the following would go into Slot2?

Answer options:

A.“secretName”
B.“password”
C.“keyVault”
D.“id”

Answer – D 
Here we have to mention the reference as “id”. 
An example is also given in the Microsoft documentation. 

Since this is clearly given in the Microsoft documentation, all other options are incorrect.
