CompTIA Network+ Question A-43

After connecting a workstation directly to a small business firewall, a network administrator is trying to manage it via HTTPS without losing its stored configuration. The only two pieces of information that the network administrator knows about the firewall are the management interface MAC address, which is 01:4a:d1:fa:b1:0e, and the administrator’s password. Which of the following will allow the administrator to log onto the firewall via HTTPS if the management’s IP address is unknown and the administrator’s workstation IP address is 192.168.0.10/23?

A. Use the reset button on the back of the firewall to restore it to its factory default, and then log onto
B. Run the following command on the administrator’s workstation: arp –s 192.168.1.200 01:4a:d1:fa:b1:0e
C. Use an SNMP tool to query the firewall properties and determine the correct management IP address
D. Use a crossover cable to connect to the console port and reconfigure the firewall management IP to 192.168.0.1

Correct Answer: B

Explanation:
Address Resolution Protocol (ARP) is used to resolve IP addresses to MAC addresses. The arp –s command adds a static permanent address to the ARP cache. This will allow the administrator to access the firewall.
