I got this question during an interview.

I'd like to ask this question from Cloud Backup Solutions in portion Cloud-Based Storage of Cloud Computing

Answer 1

Right option is (a) To scale in, the service must allow for stored data to span additional storage systems

The best explanation: Cloud storage systems that successfully scale their provisioned storage for clients often allow for the multiple storage systems to be geographically dispersed and often provide load-balancing services across different storage instances.
