An administrator needs to quickly test a possibly destructive change to a Virtual Machine (VM)...

Linked clone is the correct feature because the administrator needs to test a potentially destructive change without directly modifying the production VM. vSAN Data Protection uses native vSAN ESA snapshot technology to protect virtual machines through protection groups and scheduled snapshots. Beyond simple restore operations, vSAN Data Protection supports clone workflows that allow a VM to be created from a protected snapshot for development, validation, testing, or recovery use cases. A linked clone is especially appropriate because it can be created quickly from an existing snapshot while maintaining dependency on the base snapshot, avoiding the time and capacity impact of a full independent copy. Immutable snapshots protect recovery points from deletion or modification, but they do not themselves provide an isolated test VM. Multiple schedules only control snapshot timing. A protection group defines which VMs are protected. Replication is used for site-level protection and disaster recovery, not for rapidly testing a destructive change against a local production snapshot.
