Why the default answers are always wrong??????
To find the IP address of a device when the MAC address is known, the technician should look at the following:
A. ARP table: The ARP (Address Resolution Protocol) table maps IP addresses to MAC addresses in a local network. By checking the ARP table, the technician can find the IP address associated with a specific MAC address.
B. DHCP leases: DHCP (Dynamic Host Configuration Protocol) is used to assign IP addresses dynamically to devices on a network. DHCP leases maintain a record of the IP addresses assigned to devices. Checking the DHCP leases can help the technician find the IP address associated with a specific MAC address.
The remaining options are not directly relevant to finding the IP address based on the MAC address:
C. IP route table: The IP route table contains information about routing and the next hop for IP packets. It does not provide direct information about IP addresses based on MAC addresses.
D. DNS cache: The DNS cache stores the mapping between domain names and IP addresses. It does not directly relate to finding IP addresses based on MAC addresses.
E. MAC address table: The MAC address table is used in Ethernet switching to map MAC addresses to physical ports. It does not provide information about IP addresses.
F. STP topology: STP (Spanning Tree Protocol) is used for loop prevention in network topologies. It does not provide information about IP addresses based on MAC addresses.
Therefore, the technician should primarily look at the ARP table and DHCP leases to find the IP address associated with a known MAC address.
