The VM-Generation ID is used to prevent which issue?

• A. Duplicate IP Addresses
• B. Application duplication
• C. Duplicate Rollback Sequence Numbers
• D. Duplicate Update Sequence Numbers

Answer: (D)

VM-Generation ID is a signal that the VM’s state has changed in a fundamental way (such as after a restore from a checkpoint or other configuration change). This lets backup/replication tooling know that its view of the VM’s change history is no longer valid and it should reset its tracking. By doing so, it prevents reusing past update information, specifically the Update Sequence Numbers the change-tracking mechanism uses. If the VM has effectively been recreated or rolled back, continuing to rely on the old sequence numbers could cause the same changes to be processed twice, or missed, which would corrupt consistency. The VM-Generation ID thus prevents duplicate Update Sequence Numbers and keeps backup/replication in sync after VM state changes.
