What does site sharing involve?

Site sharing involves having multiple data centers in various locations, which is essential for enhancing redundancy, improving disaster recovery capabilities, and ensuring business continuity. By distributing operations across various geographic locations, organizations can mitigate the risk of a single point of failure. This strategy allows for load balancing and better performance, as users can be directed to the nearest data center for faster access to services and applications.

The other options do not fully capture the essence of site sharing. Utilizing cloud storage may be a part of broader IT strategies but does not specifically define site sharing. Using one backup location does not involve multiple sites, which is central to the concept of site sharing. Lastly, having all operations in a single data center contradicts the idea of site sharing by concentrating resources in one location, thus increasing vulnerability.
