A vApp containing multiple VMs has three vApp networks. The vApp is not connected to an Organization network.

Which method should the administrator use to identify the issue?

A.
Use IP Assignments to verify each IP address.

B.
Use a trace route tool to map the hops between the vApp networks.

C.
Use the vApp diagram tool to verify the network topology.

D.
Use a network sniffer to determine whether traffic is being received from all vApp networks.
