A network administrator notices that a Windows 11 workstation cannot communicate with other hosts on the same subnet. Which command-line method should the administrator use on the workstation to verify that its stored mappings between network (IP) addresses and hardware (MAC) addresses are correct?
List interface details with ipconfig /all
Clear all cached ARP entries with arp -d *
View the routing table on the default gateway using show ip route
The command arp -a displays the ARP cache, which lists each known IP address and the corresponding MAC address learned by the workstation. By comparing the information in this table against expected values, the administrator can confirm whether the workstation is resolving Layer-3 addresses to the correct Layer-2 addresses.
show ip route is a Cisco IOS command that shows a router's routing table; it offers no view of host-level ARP information.
ipconfig (or ipconfig /all) shows the workstation's own interface configuration-IP, subnet mask, default gateway, and the adapter's physical address-but it does not list the IP-to-MAC mappings for other hosts.
arp -d * clears the workstation's ARP cache; while useful for forcing the host to relearn entries, it does not display or verify the current mappings.
