Limiting local access to a network can reduce the risk of ARP poisoning. True or False?

Explanation:
The main idea is that ARP poisoning requires access to the local network’s ARP traffic. ARP is used within a LAN to map IP addresses to MAC addresses, and attackers can poison this mapping by sending forged ARP replies to devices on the same broadcast domain. If you limit who can connect to the network and segment it so fewer devices share the same local network, there are fewer sources of ARP traffic and fewer targets to poison, making ARP spoofing attacks much harder to execute. Use of controls like 802.1X/NAC, VLAN segmentation, port security, and dynamic ARP inspection further reduces the chance of a successful attack. So limiting local access does reduce the risk of ARP poisoning.
