Why are MAC addresses important in networking?

• MAC addresses are important in networking because they uniquely identify devices on a network.
• MAC addresses are not important in networking
• MAC addresses are used for encrypting network traffic
• MAC addresses can be duplicated on a network

Computer A is trying to send data to another device on the LAN but they are unsure of its location, how does Computer A figure that out?

• By using the Internet Protocol (IP)
• By using the Domain Name System (DNS)
• By using the Dynamic Host Configuration Protocol (DHCP)
• By using the Address Resolution Protocol (ARP)

Address Resolution Protocol is

• A protocol used for mapping a physical or MAC address to an IP address on a local network.
• A protocol used for mapping an IP address to a physical or MAC address on a local network.
• A protocol used for mapping an IP address to a physical or MAC address on a global network.
• A protocol used for mapping a domain name to an IP address on a local network.
