Question: Which of the following is a benefit provided by Cloud Functions?
- Relational database
- User authentication
- Machine learning
- Serverless economics
Explanation
Cloud Functions runs event-driven code without requiring server provisioning or server management. Its serverless model charges based on function execution rather than always-on infrastructure. Automatic scaling helps match compute usage to actual demand. This supports cost efficiency for lightweight automation, integration, and event-response workloads.
Why the other options are incorrect
Relational database is provided by database services such as Cloud SQL, not Cloud Functions.
User authentication is provided by identity services such as Firebase Authentication, not Cloud Functions.
Machine learning is addressed by AI and ML services, not Cloud Functions as its primary role.
