Explanation
Port mirroring requires the source and target VMs to be on the same host to efficiently copy network traffic without additional routing overhead. Option B (Source VM and Target VM are on the same host) is correct: AHV's port mirroring only works within a single host because network packets are intercepted before leaving the hypervisor. If the VMs are on different hosts, mirroring cannot be configured without additional network tools.
