What MAC address is used as the spoofed address in the SMAC lab?

• A. 00:00:55:55:44:15
• B. 11:22:33:44:55:66
• C. AA:BB:CC:DD:EE:FF
• D. 00:11:22:33:44:55

Answer: (A)

MAC spoofing labs focus on changing the source MAC in frames to impersonate another device and observe how the network reacts, including how switches update their CAM tables and how traffic is redirected or flooded as identity changes. In this SMAC lab, the spoofed address chosen is a synthetic, unused MAC address. Using a value like 00:00:55:55:44:15 ensures the frame carries a valid MAC format but isn’t tied to any real NIC on the test network. That makes it easy to recognize in captures and prevents collisions with actual devices, so you can clearly see the effects of spoofing without unintended side effects. Other addresses could function, but they might collide with real hardware or cause confusion in logs, which is why the lab selects this distinctive, unused value.
