2V0-620 · Question #158
An administrator receives a report that no real time statistics are available for a virtual machine in the vCenter Server inventory. Which two statements indicate likely causes of the problem?…
The correct answer is A. The virtual machine is powered off. B. The host containing the virtual machine is disconnected from vCenter Server. Real-time VM performance statistics require the VM to be powered on and its host to be actively connected to vCenter Server.

Why each option
Real-time VM performance statistics require the VM to be powered on and its host to be actively connected to vCenter Server.
A powered-off virtual machine has no running processes or active vCPU and memory activity, so there are no real-time metrics being generated for vCenter to collect or display.
When a host is disconnected from vCenter Server, it cannot forward performance counters or real-time statistics to vCenter, making all per-VM metrics from that host unavailable.
vCenter does not withhold real-time statistics due to insufficient data volume - statistics either exist because the VM is running on a connected host, or they do not because of a connectivity or power state issue.
If the vCenter Server service were not running, the administrator would not be able to access the vCenter inventory at all, not just statistics - the entire UI and API would be unavailable.
