A vSphere administrator has misconfigured vMotion in such a way that vMotion migrations are failing.
Based on the information shown, what is the cause of the problem?
A. The vMotion VMkernel ports on the hosts are configured with the same IP address.
B. The labels of the vMotion VMkernel ports are not identical.
C. The vMotion VMkernel ports are not labeled identically.
D. The vMotion VMkernel ports are using the same uplink.
Correct Answer: A
Explanation/Reference:
Explanation:
A: Any misconfiguration in the network will cause a failure in migration because you cannot migrate a virtual machine to the same IP address as where it is to be moved from. The exhibit shows that the original and target IP address is the same thus the virtual machine will not be moved as it is already at the supposed target. Each host in the cluster should have a vMotion vmknic, assigned a unique IP address.
Incorrect Answers:
B: The exhibit shows an IP address conflict and it is thus not the label of the ports that are problematic.
C: The exhibit shows that misconfiguration in the IP address and not the label of the port.
D: Using the same uplink will not result in a virtual machine migration failure as the exhibit shows that the IP address is incorrectly configured. In fact for vMotion to succeed the vmkernel port group should have the same security settings.
