Actual exam question from VMware's 2V0-21.23

Question #: 47
Topic #: 1

A VMkernel port is labelled PROD01 and uses the default TCP/IP stack. Currently, this VMkernel port is configured for supporting live virtual machine (VM) migrations.
Which configuration change should the administrator make to isolate live VM migration traffic from other network traffic?

A. Remove PROD01 and create a new VMkernel port and set the TCP/IP stack to vSphere vMotion.
B. Remove PROD01 and create a new VMkernel port with the TCP/IP stack set to provisioning.
C. Create a new VMkernel port and set the TCP/IP stack to provisioning.
D. Modify PROD01 by changing the TCP/IP stack to vSphere vMotion.

Selected Answer: A Default TCP/IP Stack. Manage the host-related traffic services. This stack shares a single default gateway between all configured network services. vMotion TCP/IP Stack. Isolates vMotion traffic onto its own stack. The use of this stack completely removes or deactivates vMotion traffic from the default TCP/IP stack.

D. according to this article we can edit VMKernel Port and choose between available services https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-networking/GUID-AA3656B0-005A-40A0-A293-4309C5ACF682.html

You can't change the TCP/IP stack on an existing vmkernel port, so it's A.

This is a tough call between A and C but im getting it should be A... https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-networking/GUID-D4191320-209E-4CB5-A709-C8741E713348.html Providing the Default stack is to manage host related traffic services such as vcenter and esxi hosts and system traffic, you cannot "isolate" the traffic to "VM" - why remove the default stack in its entirety instead of removing "Vmotion" capability off the default stack? - because the question states that the current default stack is already configured for supporting vm migrations SO THEREFORE "If you select the vMotion or the Provisioning TCP/IP stack, you will be able to use only these stacks to handle vMotion or Provisioning traffic on the host." Am i understanding this right, now??

why delete the TCP/IP stack and not just create a new stack for provisioning?

The question states that you are using the Default TCP/IP stack and this by default is dedicated for host management. Therefore the answer should be A since you will need to create new vmkernel for vMotion. Default TCP/IP Stack. Manage the host-related traffic services. This stack shares a single default gateway between all configured network services.

Correct answer should be A. B +C are about the provisioning stack, not related to this question. D is not possible, once you set a TCP/IP stack for the VMkernel adapter, you cannot change it later https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-networking/GUID-AA3656B0-005A-40A0-A293-4309C5ACF682.html

You are wrong, I can edit the TCP/IP stack and select vMotion!!

I think it's about what someone else said and "isolate" the traffic. Select a TCP/IP stack from the list. Once you set a TCP/IP stack for the VMkernel adapter, you cannot change it later. If you select the vMotion or the Provisioning TCP/IP stack, you will be able to use only these stacks to handle vMotion or Provisioning traffic on the host. All VMkernel adapters for vMotion on the default TCP/IP stack are disabled for future vMotion sessions. If you set the Provisioning TCP/IP stack, VMkernel adapters on the default TCP/IP stack are disabled for operations that include Provisioning traffic, such as virtual machine cold migration, cloning, and snapshot migration. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.networking.doc/GUID-AA3656B0-005A-40A0-A293-4309C5ACF682.html

To enable the vMotion TCP/IP stack, assign a new VMkernel adapter to it.
