An administrator is investigating a scenario where a particular office computer is unable to reach shared network resources despite confirming that it has been assigned a correct IP configuration. The computer is capable of pinging its assigned IP and the loopback address, but cannot interact with other hosts in its segment. Based on these symptoms, which diagnostic tool should be utilized first?
Deploy a protocol analyzer to monitor and review traffic passing through the network gateway.
Reconfigure the settings on the wireless LAN controller for improved reliability.
Initiate a traceroute command to map the route towards a distant server.
Use the ARP diagnostic tool on the affected computer to inspect its ARP table.
