You authored the topics and added actions using the Authoring canvas. 
You are ready to deploy the chatbot to the company’s website, Teams, and Facebook channels. 
What must you do before you can share the new shiny chatbot?

Answer options:

A.Add custom entities
B.Add new topics
C.Test your bot
D.Publish your bot
E.Create an Azure AD security group to share your bot with

Correct Answer: D 
After you authored the topics (which means to create a new topic and provide the set of trigger phrases that will invoke your bot) and added your bot’s actions using the Authoring canvas, you are ready to Publish your bot. Of course, you can test and debug your bot before you publish. But before you deploy the bot, you must publish it. 

After you publish your bot, you can add it to your website and the list of channels that the Power Virtual Agents portal provides.
Option A is incorrect because the Entities represent information that the bot is trying to identify based on natural language understanding from the customer`s conversation. When you finish with the chatbot`s creation, you need to publish it and not add the new custom Entities before the deployment.
Option B is incorrect because adding new topics is not required before the bot`s deployment. You need to publish the bot before adding it to the company`s website, Teams, and Facebook channels.
Option C is incorrect because testing the bot before deployment is good practice, but it is not required for the deployment. Only publishing the bot is necessary before adding it to the company`s website, Teams, and Facebook channels.
Option E is incorrect because the chatbot`s publishing does not require creating any additional Azure AD security group. You can add extra security for the bot`s sharing if you need to. Please review the security options under the Manage/Security sections of the Power Virtual Agents portal.
