Which feature can an administrator configure to have a copy of critical virtual machines in another cluster? (Choose the best answer.)

vSphere Storage vMotion migrates the storage of a running VM to a different datastore within the same environment - it does not create or maintain ongoing copies in another cluster.

vSphere Fault Tolerance maintains a live shadow VM that mirrors the primary VM in real time for zero-downtime failover, but it operates within the same or peered clusters and is not designed for cross-cluster replication copies.

vSphere Replication is a hypervisor-based replication engine built into ESXi that continuously replicates VM disk changes to a target site or cluster. It operates asynchronously and maintains a copy of the VM at the recovery site, making it the correct tool for keeping a replica of critical VMs in another cluster. It integrates with VMware Site Recovery Manager for orchestrated failover.

Instant Clone creates rapid, memory-efficient thin clones from a running parent VM for use cases like VDI and stateless workloads - it does not provide replication or disaster recovery copies.
