Google Cloud Professional Cloud Developer PCD — Topic 1 Question 161

Question

You are building a mobile application that will store hierarchical data structures in a database. The application will enable users working offline to sync changes when they are back online. A backend service will enrich the data in the database using a service account. The application is expected to be very popular and needs to scale seamlessly and securely. Which database and IAM role should you use?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Use Firestore in Native mode and assign the roles/datastore.user role to the service account. Firestore is a serverless, autoscaling NoSQL document database ideal for app and user data. Datastore (Firestore in Datastore mode) is a serverless NoSQL database for user profiles and app state. A service account provides an identity for workloads to access Google Cloud APIs securely.
