2. You are leading a development team that integrates GitHub Copilot into a project. Some of the project files contain proprietary algorithms and confidential business logic that you don’t want GitHub Copilot to process. You are aware that Copilot uses all the content in the enabled files, including code, comments, and even incomplete code snippets, to generate its suggestions. How should you manage Copilot’s usage to exclude specific content from being used during code generation while continuing to leverage Copilot’s functionality for other parts of the project?

You Might Be Interested In

Option A: Manually obfuscate any confidential code and comments before using Copilot.
Option B: Use environment variables to control Copilot’s access to sensitive content.
Option C: Rely on Copilot’s built-in exclusion filters to automatically exclude sensitive code.
Option D: Disable GitHub Copilot for the project’s sensitive files and repositories.

Correct Answer: D

3. You are developing a full-stack application with a team that uses multiple programming languages (e.g., Python for back-end logic, JavaScript for front-end, and SQL for the database). GitHub Copilot is being used to speed up development.
