A security administrator wants to implement a logon script that will prevent MITM attacks on the local LAN. Which of the following commands should the security administrator implement within the…

The `arp -s` command adds a static entry to the Address Resolution Protocol (ARP) cache, permanently associating the IP address (192.168.1.1) with its legitimate MAC address (00-3a-d1-fa-b1-06). This static mapping prevents an attacker from injecting false ARP entries into the local cache, thereby mitigating ARP spoofing, a common mechanism for Man-in-the-Middle (MITM) attacks on a LAN.

The `dig` command is a DNS lookup utility used for querying domain name servers and does not provide any functionality to prevent MITM attacks on the local network.

The `nmap` command is a network scanner used for discovery and security auditing, but it does not actively configure network settings or security mechanisms to prevent MITM attacks.

The `tcpdump` command is a packet sniffer used for monitoring network traffic, which can help detect anomalies but does not prevent MITM attacks from occurring.
