NEW QUESTION # 28
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 with the TCP/IP stack set to provisioning.
- B. Modify PROD01 by changing the TCP/IP stack to vSphere vMotion.
- C. Create a new VMkernel port and set the TCP/IP stack to provisioning.
- D. Remove PROD01 and create a new VMkernel port and set the TCP/IP stack to vSphere vMotion.
Answer: D
Explanation:
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.

Which feature would allow for the non-disruptive migration of a virtual machine between two clusters in a single VMware vCenter instance?
- A. vSphere vMotion
- B. Cross vCenter Migration
- C. vSphere Storage vMotion
- D. vSphere Fault Tolerance
Answer: A
Explanation:
vSphere vMotion allows for the non-disruptive migration of a virtual machine between two clusters in a single vCenter instance, as long as there is shared storage and network connectivity between the clusters.
Reference:
vMotion is used to move the VM to a different cluster within the same vCenter. This only works if both clusters share the same storage. If they don't you also need to perform a Storage vMotion. Cross vCenter Migration is only used to migrate to a different vCenter.
