🛡️ Free practice test question from: ARP spoofing (Security+)

The scenario describes an Address Resolution Protocol (ARP) spoofing attack, which is a type of man-in-the-middle (MITM) network attack. In this case, a malicious device is sending fraudulent ARP messages to associate its MAC address with the network gateway's IP address. This allows the attacker to intercept, modify, or redirect network traffic.

Static ARP entries (A) would take too long to configure network-wide and may not adapt to dynamic environments. Network segmentation (B) is effective for long-term containment but does not address the ongoing attack. While 802.1X (D) is a robust solution, implementing it immediately requires significant configuration changes and would not provide a quick response to the current threat.

INFO:
ARP (Address Resolution Protocol) poisoning, while not completely obsolete, has become less common in modern network environments due to several technological and security advances (modern switches, network segmentation,ACLs)
