In your LUIS application, you would want to add authors and contributors. While you have the option to add these users through the Azure Portal, you intend to achieve this objective using the REST calls. This capability would eventually be utilized in the user self-service catalog of your enterprise. Review the answer choices given below and choose the REST call that you will use to replace the current user access list with the new list.

Answer options:

A.PUT {Endpoint}/luis/api/v2.0/apps/{appId}/permissions
B.GET {Endpoint}/luis/api/v2.0/apps/{appId}/permissions
C.POST {Endpoint}/luis/api/v2.0/apps/{appId}/permissions
D.DELETE {Endpoint}/luis/api/v2.0/apps/{appId}/permissions

Correct Answer: A
Option A is correct because the PUT command is used to replace the current user list with a new user list. Endpoint here is to be replaced with the Cognitive Services resource endpoint and the list of users containing their email ids.
Option B is incorrect because the GET command is used for getting the list of user emails. These users have the permission to access the LUIS application.
Option C is incorrect because the POST command is used to add a user to the allowed list of users. However, the requirement here is to replace the list of users with a new one and hence requires an update command.
Option D is incorrect because the DELETE command is used to delete a user from the allowed list of users.
