2. In the networking inventory view, get lists showing the hosts and VMs that are connected to different networks and port groups |

| What steps can you take to verify a given virtual machine is configured with the correct network resources? |
|
Definition
1. Ensure the network associated with your VMs NICs actually exists and is spelled correctly within your virtual switches and that the 'connected' box is checked
2. Ensure the VM has no underlying storage problems or is not under contention
3. Verify that networking from within your guest OS is configured properly
4. If the VM was converted from a physical machine, verify there are no hidden network adapters
5. Verify that the vSwitch has enough ports to support the VM |

Term
| Security policies must be consistent across Port Groups across hosts, or vMotion will fail. Give an example. |
|
Definition
| E.g. if one vSwitch was set to accept Promiscuous Mode and it is set to Reject on the other host, vMotion will fail. |
|
|
Term
| T/F: physical NICs that are assigned to a virtual switch should be configured the same (speed, vLANs, etc), on the physical switch |
