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. Reference: https://docs.vmware.com/en/VMware-vSphere/8.0/vsan-network-design-guide/GUID-51E2022C-6F78-4CE0-B4C7-6ED1E90F2D95.html

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.
