Solution
When you take the exam, you will choose which language (C# or Python) you want to take the exam with. AI-102 is a developer exam with code questions so you need to know how to perform work with Cognitive Services using that language. You also need to know how to call the REST APIs with tools such as curl. For bots there is using the Bot Framework SDK which supports C#, Python, and Node.js
The learning paths probably don't cover this part and you need to do the exercises/labs and read docs.microsoft.com as well as looking at the REST API https://docs.microsoft.com/en-us/rest/api/cognitiveservices/
