What is true about migrating VM21 to the new host?

A virtual machine, VM21, will be migrated between two ESXi 5.x hosts, labeled ESXi01 and ESXi02. Each host has two vSphere Standard Switches (vSS), configured as follows:

1. vSwitch0 has a portgroup labeled Management and a portgroup labeled vMotion.

2. The Management portgroup contains a vmkernel port tagged for management traffic.

3. The vMotion portgroup contains a vmkernel port tagged for vMotion traffic.

4. vSwitch0 on ESXi01 has an uplink attached to the 10.1.20.0/24 network.

5. vSwitch0 on ESXi02 has an uplink connected to the 10.1.30.0/24 network.

6. Each host has a vSwitch1 with a Production portgroup used by virtual machine traffic.

7. Each vSwitch1 has an uplink attached to the 10.1.40.0/24 network.

What is true about migrating VM21 to the new host?

vMotion would be supported in this configuration.

B.
Storage vMotion would not be supported in this configuration.

C.
vMotion would not be supported in this configuration.

D.
Storage vMotion would be supported if the storage device supports VAAI.

    I think the reason is because both switches are in different subnets, so they couldn’t communicate each other by the uplink ports, therefore vmotion traffic is dropped at the second switch.

    … another tricky question – go figure 🙁
    According to the VMware 5.1 doco – the Network vMotion requirements are met:

    Configure the virtual networks on vMotion enabled hosts as follows:
    – On each host, configure a VMkernel port group for vMotion.
    – Ensure that virtual machines have access to the same subnets on source and destination hosts.
    – If you are using standard switches for networking, ensure that the network labels used for virtual machine port groups are consistent across hosts. During a migration with vMotion, vCenter Server assigns virtual machines to port groups based on matching network labels.
