How is cloud storage defined?

• A. Data stored on a single on-site server
• B. Data residing on collections of servers that may be located anywhere in the world
• C. Data stored on mobile devices only
• D. Data kept in local backups only

Answer: (D)

Cloud storage is storing data on remote servers that you access over the internet, typically spread across multiple servers in data centers that can be in different locations. This setup lets you reach your files from various devices and places, and it provides redundancy and scalability because data is stored on more than one server. The description that fits cloud storage is data residing on collections of servers that may be located anywhere in the world. In contrast, storing data on a single on-site server, keeping data only on mobile devices, or maintaining local backups only describes storage that is not cloud-based.
