Firebase Storage is designed for storing files in the cloud and works well with React Native.

Before uploading a file to cloud storage, you need to:

A Convert the file to text

C Delete the file from the device

D Restart the app

You must know where the file is locally to upload it to the cloud.

How can you protect files stored in cloud storage?

B Store files without any restrictions

C Use authentication and storage rules

D Disable internet access

Authentication and rules help control who can access or modify files.
