How can you monitor and filter data in a virtual network when traffic might not cross the physical network?

Routing all traffic to the physical network adds unnecessary overhead and may not be technically feasible for east-west virtual traffic that never leaves the hypervisor.

B alone is incomplete because a virtual monitoring tool on the same physical hardware (option C) is equally valid and should be included.

C alone is incomplete because a virtual appliance on the same virtual network (option B) is also a valid and commonly used monitoring approach.

D includes option A, which involves unnecessary physical network routing that is impractical when effective virtual monitoring solutions exist.

Options B and C are both valid because routing traffic to a virtual appliance on the same virtual network or to a virtual monitoring tool on the same physical hardware both enable packet capture without requiring traffic to leave the virtual environment - these approaches place software-defined inspection points within the virtualization layer where east-west traffic flows.
