After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You train and register a machine learning model.
You plan to deploy the model as a real-time web service. Applications must use key-based authentication to use the model.
You need to deploy the web service.
Solution:
Create an AciWebservice instance.
Set the value of the auth_enabled property to False.
Set the value of the token_auth_enabled property to True.
Deploy the model to the service.
Does the solution meet the goal?

A. Yes
B. No

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)

No.

B. No. The solution does not meet the goal as it specifies setting the auth_enabled property to False, which means that there will be no authentication for accessing the web service. Additionally, the token_auth_enabled property is set to True, but it requires a token for authentication, which is contradictory to the previous property. To meet the goal of key-based authentication, the auth_enabled property should be set to True and the token_auth_enabled property should be set to False. Additionally, other configurations related to key-based authentication such as primary_key or secondary_key should be specified.

Selected Answer: B

Falsch - token and key-based are different authentication methods.

The answer is FALSE https://azure.github.io/azureml-sdk-for-r/articles/deploying-models.html in aks there can be set authentication two way key ==> auth_enabled = TRUE token ==> token_auth_enabled = TRUE problem specified with must authenticated by key-based
