A company is planning to deploy a database application that requires high availability. In the event of a host failure, the application must sustain only minimal service interruption. Which technology

Remote data replication copies data to a distant site to support disaster recovery, but it does not provide automatic host-level failover or minimize service interruption when a local host fails.

Local data replication mirrors data within the same site to protect against storage failures or data corruption, but it does not address compute host failure or provide automatic application failover.

A cluster groups multiple server nodes so that if one host fails, another node automatically takes ownership of the database application and its workload within seconds to minutes, meeting the requirement for minimal service interruption. The shared or replicated storage and heartbeat mechanisms built into cluster software detect the failure and trigger failover without manual intervention, providing the continuous availability the company requires.

Two-stage backup is a data protection strategy that stages backups to disk before moving them to tape, and it provides no high-availability or failover capability for application continuity.
