VCA vSphere vMotion & Live Migration

Question 1

What is the primary purpose of VMware vMotion?

Accepted Answer

To live-migrate a running virtual machine between hosts with no downtime

Answer

vMotion enables live migration of a running virtual machine from one ESXi host to another with zero downtime, maintaining all active network connections.

Question 2

Which shared resource is required between source and destination hosts for a vMotion migration to succeed?

Accepted Answer

Shared storage accessible by both hosts

Answer

vMotion requires that both the source and destination ESXi hosts have access to the same shared storage (e.g., NFS, SAN) so the VM's disk files are reachable from the destination.

Question 3

What is the minimum recommended network bandwidth for a vMotion VMkernel adapter?

Accepted Answer

1 Gbps

Answer

VMware recommends at least a 1 Gbps dedicated network for vMotion to ensure fast memory-state transfer without impacting production traffic.

Question 4

What does Storage vMotion allow an administrator to do?

Accepted Answer

Move a running VM's disk files to a different datastore without downtime

Answer

Storage vMotion migrates a virtual machine's disk files (VMDKs) from one datastore to another while the VM remains powered on and running.

Question 5

Which VMkernel port must be enabled on an ESXi host to support vMotion traffic?

Accepted Answer

vMotion VMkernel port

Answer

A VMkernel adapter with the vMotion service enabled must be configured on both source and destination hosts for vMotion migrations to occur.
