Which three statements about MAC addresses are correct?
Choose three
A) To communicate with other devices on a network, a network device must have a unique MAC address
B) The MAC address is also referred to as the IP address
C) The MAC address of a device must be configured in the Cisco IOS CLI by a user with administrative privileges
D) A MAC address contains two main components, the first of which identifies the manufacturer of the hardware and the second of which uniquely identifies the hardware
E) An example of a MAC address is 0A:26:B8:D6:65:90
F) A MAC address contains two main components, the first of which identifies the network on which the host resides and the second of which uniquely identifies the host on the network
Solution
Correct answer: A) To communicate with other devices on a network, a network device must have a unique MAC address and D) A MAC address contains two main components, the first of which identifies the manufacturer of the hardware and the second of which uniquely identifies the hardware and E) An example of a MAC address is 0A:26:B8:D6:65:90.
MAC addresses are unique identifiers assigned to network interfaces for communications on the physical network segment. They are used to identify devices on a local network and are crucial for the operation of the network. The MAC address is not the same as the IP address; the IP address is used for routing packets across networks, while the MAC address is used for communication within a network. The MAC address is indeed configured in the Cisco IOS CLI by a user with administrative privileges, but this statement was not provided in the options.
