2V0-21.23 Question 403
Single answerYou are tasked with migrating a virtual machine (VM) from one ESXi host to another within the same vSphere cluster. The VM has an active workload and requires minimal downtime. The source host and the destination host use shared storage, and both are connected to the same vMotion network. Which migration method is most appropriate for this scenario?
- A
Cold migration
- B
vMotion (live migration)
- C
Storage vMotion
- D
Cross vCenter vMotion
Show answer and explanation
Correct answer: B
Explanation
In this scenario, the VM needs to be migrated between two ESXi hosts with minimal downtime while keeping the workload active. vMotion (live migration) is specifically designed for this purpose. It allows the VM to be transferred seamlessly between hosts without impacting availability, provided the hosts share storage and are connected to the same vMotion network.
- A. Incorrect.
Cold migration requires shutting down the VM before migrating it to another host or datastore, which is unsuitable for a scenario requiring minimal downtime.
- B. Correct.
vMotion (live migration) allows the VM to be migrated between hosts with no downtime, making it the best option for a VM with an active workload and shared storage.
- C. Incorrect.
Storage vMotion is used to migrate a VM's storage to another datastore without downtime, but it does not address the need to migrate between hosts.
- D. Incorrect.
Cross vCenter vMotion is used to migrate VMs across different vCenter Server instances, which is not relevant for a migration within the same vSphere cluster.
