ARP operates within which scope of the network?

Explanation:
ARP is used to translate an IPv4 address to its corresponding MAC address, but it only works within the local broadcast domain. When a device needs to resolve an address, it sends a broadcast ARP request to all devices on its local subnet; only the device with the matching IP replies. Routers don’t forward ARP requests because they operate to separate broadcast domains, so ARP cannot cross network boundaries. That means ARP applies to the local network segment, which can be a physical LAN or a VLAN-defined broadcast domain. For communication beyond that local segment, routing occurs and ARP is needed again on each hop. So ARP operates on local network segments only.
