You create a chatbot that provides local information.
Users can get information about the local weather, working hours of the shops, current movies playing in local theaters, and others.
At the beginning of a conversation, the bot asks users to input their city name or a zip code.
What type of the variable does chatbot use to store this information?

A. B. C. D. E.Correct Answer: D
During conversations, Power Virtual Agents chatbots collect user's information and store it in the variables.
The variables help chatbots to keep an intelligent conversation by avoiding asking to provide the same information several times.
The variables also serve as parameters and outputs in the chatbot's integration with Power Automate and Power Apps.
The chatbot's variables have their scope.
There are two types of variables: Topic - variables with a limited scope that can be used within a topic.
Bot - variables with “global” access from any topic across the entire bot during a single user session.
By default, the variables have a scope of topic where they are created.
When the bot asks users to provide information about their city or a zip code, this information is stored in a variable with the "global" scope - bot variable.
Because if the bot stores this information in a variable with the topic's scope, it must ask users to supply their city or zip code once more when they change the topic from the local weather to the movies.
All other options are incorrect.

The variable type that the chatbot uses to store the user's input (city name or zip code) would be a local variable.
Local variables are variables that are defined and used within the scope of a particular function or task. In this case, the chatbot would define a variable to store the user's input within the scope of the conversation. The variable would be used throughout the conversation to retrieve the necessary information based on the user's input.
Other variable types are not appropriate for this scenario. Global variables are variables that are accessible throughout an entire program, but this would not be necessary or efficient for the chatbot. Topic variables are variables that store information about a particular topic within a conversation, which is not relevant to storing the user's input. Bot variables are variables that are accessible throughout the chatbot's entire execution, but this would not be necessary for storing the user's input either. Public variables are variables that are accessible to other programs or modules, which is not applicable in this scenario.
Therefore, the appropriate variable type for the chatbot to use to store the user's input (city name or zip code) is a local variable.
