VCA vSphere vMotion & Live Migration 3

Question 1

What is Long Distance vMotion in vSphere?

Accepted Answer

Live VM migration across geographically separated data centers over a WAN link

Answer

vMotion between VMs on the same ESXi host

Answer

Migrating VMs across storage arrays using Storage vMotion

Answer

Automated vMotion triggered by hardware failure detection

Question 2

Which of the following network conditions is required when performing vMotion between hosts on different subnets?

Accepted Answer

A routed network path must exist between the vMotion VMkernel adapters on both hosts

Answer

Both hosts must use the same IP address on their vMotion VMkernel adapters

Answer

Both hosts must be connected to the same physical switch

Answer

vMotion cannot be performed between hosts on different subnets

Question 3

What happens to the VM's MAC address during a vMotion migration?

Accepted Answer

The MAC address is preserved — it stays the same on the destination host

Answer

The MAC address changes to match the destination host's physical NIC

Answer

A new MAC address is randomly assigned after migration completes

Answer

The MAC address is temporarily released and re-registered with vCenter

Question 4

Which vSphere component is responsible for orchestrating a vMotion operation?

Accepted Answer

vCenter Server coordinates the vMotion operation between the source and destination hosts

Answer

The ESXi host VMkernel running on the source host only

Answer

The vSphere Web Client browser plugin

Answer

The virtual machine's guest operating system

Question 5

What is the purpose of the 'stun' phase at the end of a vMotion migration?

Accepted Answer

To briefly pause the VM on the source to copy the final dirty memory pages and transfer execution to the destination

Answer

To freeze the VM on the destination host while snapshots are created

Answer

To pause network traffic while the MAC address is updated

Answer

To allow the guest OS to detect and acknowledge the new hardware environment

Question 6

Which vSphere migration type allows moving both the compute state AND the storage of a running VM simultaneously?

Accepted Answer

Combined vMotion (compute + storage vMotion)

Answer

Standard vMotion

Answer

Cold Migration

Answer

vSphere Replication

Question 7

Which condition would PREVENT a vMotion from succeeding?

Accepted Answer

The VM has a CD/DVD drive connected to a host-local ISO file

Answer

The source and destination hosts are in the same vCenter cluster

Answer

The VM is running a Windows Server guest operating system

Answer

The destination host has more physical RAM than the source host
