The answer is that the VMkernel adapter must be enabled for vMotion and must reside on the same subnet as the destination host. This is because vMotion relies on a direct, layer-2 network path between the source and target ESXi hosts to transfer memory and state information without routing overhead; if the VMkernel interfaces are on different subnets, the traffic would require a gateway, introducing latency and potential failure points. On the VMware Certified Professional Data Center Virtualization VCP-DCV exam, this question tests your understanding of the fundamental vMotion prerequisites on a vSphere distributed switch, often appearing as a multiple-select trap where candidates mistakenly think a specific VLAN ID or static IP is required. A common pitfall is confusing the VMkernel adapter’s vMotion enablement with other settings like uplink teaming or IP assignment, which are irrelevant here. Remember the mnemonic “Same Subnet, vMotion Set” to quickly recall the two non-negotiable conditions.
VCP-DCV Configure and Manage vSphere Networking Practice Question
This VCP-DCV practice question tests your understanding of configure and manage vsphere networking. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which two conditions must be met for a VMkernel adapter to be used for vMotion on a distributed switch? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The VMkernel adapter must be in the same subnet as the destination host.
Options B and D are correct. The VMkernel adapter must be in the same subnet as the destination host (B) and must be enabled for vMotion (D). VLAN ID can be any, static IP is not required, and uplink teaming mode is irrelevant.
Key principle: A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
The VMkernel adapter must be in the same subnet as the destination host.
Why this is correct
vMotion requires IP connectivity between hosts on the same subnet.
Related concept
Access ports place end devices into a single VLAN.
✓
The VMkernel adapter must be enabled for vMotion.
Why this is correct
vMotion must be enabled on the VMkernel adapter.
Related concept
Access ports place end devices into a single VLAN.
✗
The physical uplinks must be in active/standby mode.
Why it's wrong here
Teaming mode does not affect vMotion functionality.
✗
The port group must have VLAN ID 0.
Why it's wrong here
VLAN ID can be any value; it doesn't have to be 0.
✗
The port group must be configured with a static IP address.
Common exam trap: an active trunk can still block the VLAN you need
A trunk being up does not prove every VLAN is crossing it. Check allowed VLAN lists, native VLAN mismatch, VLAN existence and access-port assignment.
Detailed technical explanation
How to think about this question
VLAN questions usually combine access-port and trunking clues. The key is to identify whether the issue is local to one switchport, caused by the trunk, or caused by the VLAN not existing where it needs to exist.
KKey Concepts to Remember
Access ports place end devices into a single VLAN.
Trunk ports carry multiple VLANs between switches.
Allowed VLAN lists decide which VLANs can cross a trunk.
Native VLAN mismatch can create confusing symptoms.
TExam Day Tips
→Use show vlan brief to verify access VLANs.
→Use show interfaces trunk to verify trunk state and allowed VLANs.
→Do not treat every same-VLAN issue as a routing problem.
Key takeaway
A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.
Real-world example
How this comes up in practice
A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
What to study next
Got this wrong? Here's your next step.
Review VLAN allowed lists, native VLAN mismatch detection, and how to verify VLAN membership with show vlan brief and show interfaces trunk. Then practise related VCP-DCV questions on switching, trunking, and access-port configuration.

Variation 1. An administrator needs to ensure that virtual machines can be migrated between ESXi hosts using vMotion. The virtual machines are connected to a standard vSwitch port group named 'Production'. What must be consistent across all hosts?
easy
✓ A.Port group name 'Production'
B.MTU size
C.Number of uplinks
D.Load balancing policy
Why A: Option A is correct because vMotion requires the same port group name on source and target host. Option B is incorrect because MTU may differ if not using jumbo frames. Option C is incorrect because number of uplinks can vary. Option D is incorrect because load balancing policy does not affect vMotion compatibility.
