1. HPE Zerto Administration Guide for vSphere: In the section "The Move VPG Workflow," the guide details the process. Step 6, "Commit the Move," is followed by the system powering off the source VMs. The guide explicitly states, "The virtual machines in the source site are not deleted." This confirms that the source VMs are retained for rollback purposes. (Reference: Zerto 9.7 Administration Guide for vSphere, Page 298).
2. HPE Zerto Technical Documentation - "Moving Protected Workloads": This documentation clarifies the distinction between Move and Failover. It states, "When the move is committed, the virtual machines at the protected site are powered off... The virtual machines are not removed from the protected site, enabling you to roll back to these machines if the move is not successful." This directly supports the correct answer and refutes option B.
3. HPE Zerto Official Product Information: Descriptions of the Zerto platform consistently highlight the RPO of seconds and RTO of minutes. The claim of an "RTO of seconds" is inaccurate for a full VM migration and boot-up process, making option D incorrect. The Move feature is specifically designed for planned events, where a few minutes of downtime is acceptable and scheduled.
