What are the two methods to download a wallet file in ADB?

The correct answer highlights the methods of downloading a wallet file specifically within the context of ADB (Automatic Database Backups) management. Using a database connection and accessing the Administration tab in the console allows users to efficiently manage database files and settings directly from the administrative interface. This method is typically integrated into the ADB management tools, ensuring that users follow proper protocols while securely accessing wallet files.

The other options do not pertain to the standard methods for downloading a wallet file in ADB. While the command line may be used for other database management tasks, it is not standard for wallet file downloads in this context. A direct download link and email request is not a recognized method for secure file management in ADB, and cloud storage and FTP methods are more general data transfer protocols that do not specifically apply to the practices around database administration and submission of wallet files. Understanding the administrative tools and methods provided within ADB is crucial for safe and effective database management.
