The correct answer is D. The system is virtualized. When multiple MAC addresses appear on a single switch port, it indicates that multiple virtual machines are running on a single physical host.

Question
Pete, a security engineer, is trying to inventory all servers in a rack. The engineer launches RDP sessions to five different PCs and notices that the hardware properties are similar. Additionally, the MAC addresses of all five servers appear on the same switch port. Which of the following is MOST likely the cause?
Options
- AThe system is running 802.1x.
- BThe system is using NAC.
- CThe system is in active-standby mode.
- DThe system is virtualized.

Explanation
When multiple MAC addresses appear on a single switch port, it indicates that multiple virtual machines are running on a single physical host. The hypervisor (physical server) connects to the switch via one physical NIC, and all VMs share that uplink - so the switch sees all VM MAC addresses on the same port. The similar hardware properties are consistent with VMs cloned or templated from the same base image. 802.1x is a port-based network access control protocol. NAC controls network access based on device posture. Active-standby is a high-availability mode involving two devices, not five sharing one port.
