Google Cloud Platform Fundamentals: Core Infrastructure Quiz Answers

Here you will find Google Cloud Platform Fundamentals: Core Infrastructure Coursera course all quiz answers for free. Google Cloud Platform (GCP) is a product offered by Google. It is a suite of cloud computing services that runs on the same infrastructure that Google uses internally for its own products like Google Search, YouTube, Gmail, and Google Drive. Google Cloud works by providing client libraries that enable users to easily create and manage resources.

Google Cloud Platform provides serverless computing environments, infrastructure as a service, and platform as a service.
