The correct option is Copilot is trained on a static snapshot of publicly available code so its training data can be many months old or even more than a year behind current APIs.

This is accurate because the tool generates suggestions from a machine learning model that was trained on a fixed set of public code and natural language rather than pulling examples from the internet when you type. Model updates happen periodically which introduces lag between the latest changes in the ecosystem and what the model has learned. That lag explains why you may see deprecated APIs or outmoded patterns in suggestions.

Vendor guidance also clarifies that the system does not browse the web or clone repositories during suggestion time. It relies on your current file context and the patterns embedded in the model which means its relevance depends on when the training data was last refreshed.

Copilot retrieves fresh code directly from public GitHub repositories in real time for each suggestion so outputs always match the newest commits is incorrect because it does not fetch live code from repositories. Suggestions are produced from the model’s learned patterns and not from real time scraping of public commits.

Copilot augments suggestions by querying Google Cloud services like BigQuery and Cloud Source Repositories at generation time to keep examples current is incorrect because the system does not query external cloud services to form suggestions. Furthermore Cloud Source Repositories has been retired by Google which makes this claim even less likely on newer exams.

Copilot retrains every day on the latest repositories and documentation which ensures its guidance always mirrors the newest best practices is incorrect because training is not a daily process and there is no guarantee that suggestions will always reflect the most current best practices.
