Which statement about live VM migration is true?

• A. It enables moving VMs with minimal downtime during maintenance.
• B. It creates automatic backups.
• C. It eliminates need for backups.
• D. It requires complete system shutdown.

Answer: (D)

Live VM migration moves a running virtual machine from one host to another with little to no downtime, which is exactly what maintenance or load balancing scenarios need. The process transfers the VM’s memory and state while it’s still running, and only a brief moment at the end is needed to synchronize final changes and resume on the new host. That minimal downtime is the hallmark of live migration, allowing maintenance without fully stopping the VM. This isn’t about automatic backups, and migration doesn’t replace or eliminate the need for backups. Backups are a separate safety measure to protect against data loss, while live migration focuses on moving the running VM to another host. It also certainly doesn’t require a complete system shutdown—the opposite is true: the goal is to avoid downtime. So the true statement is that live VM migration enables moving VMs with minimal downtime during maintenance.
