Actual exam question from Google's Cloud Digital Leader

Question #: 19
Topic #: 1

You are a program manager for a team of developers who are building an event-driven application to allow users to follow one another's activities in the app. Each time a user adds himself as a follower of another user, a write occurs in the real-time database.
The developers will develop a lightweight piece of code that can respond to database writes and generate a notification to let the appropriate users know that they have gained new followers. The code should integrate with other cloud services such as Pub/Sub, Firebase, and Cloud APIs to streamline the orchestration process. The application requires a platform that automatically manages underlying infrastructure and scales to zero when there is no activity.
Which primary compute resource should your developers select, given these requirements?

A. Google Kubernetes Engine
B. Cloud Functions
C. App Engine flexible environment
D. Compute Engine

Selected Answer: B

Given the requirements of automatically managing underlying infrastructure, scaling to zero when there is no activity, and integrating with other cloud services like Pub/Sub, Firebase, and Cloud APIs, the appropriate compute resource for your developers to select would be Cloud Functions in Google Cloud Platform (GCP). Cloud Functions is a serverless compute service that allows you to run event-driven code in a fully managed environment. It is designed to execute short-lived functions in response to various events, such as database writes, file uploads, HTTP requests, and Pub/Sub messages.
