You need to deploy the web service.

Show Suggested Answer

Suggested Answer: B 🗳️
Instead use only auth_enabled = TRUE
Note: Key-based authentication.
Web services deployed on AKS have key-based auth enabled by default. ACI-deployed services have key-based auth disabled by default, but you can enable it by setting auth_enabled = TRUE when creating the ACI web service. The following is an example of creating an ACI deployment configuration with key-based auth enabled. deployment_config <- aci_webservice_deployment_config(cpu_cores = 1, memory_gb = 1, auth_enabled = TRUE)

deployment_config <- aci_webservice_deployment_config(cpu_cores = 1, memory_gb = 1, auth_enabled = TRUE) To fetch the auth keys, use get_webservice_keys(). To regenerate a key, use the generate_new_webservice_key() function: # Generate the primary auth key primary_key <- generate_new_webservice_key(service, key_type = "Primary") # Generate the secondary auth key secondary_key <- generate_new_webservice_key(service, key_type = "Secondary") https://azure.github.io/azureml-sdk-for-r/articles/deploying-models.html#key-based-authentication
