Which technique allows you to change (spoof) the MAC address of your NIC instantly?

• A. MAC duplicating
• B. XArp
• C. DAI
• D. TMAC

Answer: (D)

MAC spoofing means changing the network card’s hardware address while the system is running. TMAC, which stands for Technitium MAC Address Changer, is a Windows utility designed specifically to alter the NIC’s MAC address instantly by updating the driver/registry so the new value is used immediately, without needing a reboot. It can set a chosen MAC or generate a random one and applies the change right away, making it the quickest and most reliable way to spoof the MAC. Other options focus on different tasks: one is used for manipulating ARP entries and discovery rather than changing the NIC’s address, and another deals with ARP security validation on switches rather than altering the local MAC. The idea of “MAC duplicating” isn’t a standard tool or method for immediate MAC changes.
