Final answer:
Multi-site clusters provide high availability by enabling continuous operations during a site failure and enhance disaster recovery by being geographically dispersed to avoid simultaneous incapacitation by local disruptions.
Step-by-step explanation:
The two key benefits of multi-site clusters are high availability and disaster recovery. High availability is achieved because multi-site clustering allows for the continuous operation of services in the event of a site failure, as the workload can be automatically moved to another site. Disaster recovery is enhanced as multi-site clusters can provide geographically separate locations meaning that events affecting physical proximity, like natural disasters, will not incapacitate all clustered sites simultaneously. By having a multi-site cluster, organizations ensure that critical systems remain online and data integrity is maintained, even in the face of unexpected disruptions.
