Question

Which of the following is true of a MAC address?

a. All binary 1s in the source address indicates a broadcast frame.
b. A destination address of 12 hexadecimal Fs is a broadcast.
c. It's sometimes called a logical address.
d. It uniquely identifies both the local network and the individual computer on that network.
e. It is composed of 12 bits.

Answer 1

The correct statement about a MAC address is b, which specifies that a frame with a destination address of 12 hexadecimal Fs (FF:FF:FF:FF:FF:FF) is a broadcast meant for all devices on the local network. MAC addresses are unique identifiers for network devices that consist of 48-bits (6 bytes) in hexadecimal format.

Step-by-step explanation:

The question is asking which statement is true about a MAC address. The correct answer is b. A destination address of 12 hexadecimal Fs is a broadcast.

This means that when a frame is being sent to every device on the local network, the destination MAC address is set to FF:FF:FF:FF:FF:FF. A MAC address, or Media Access Control address, is a unique identifier assigned to network interfaces for communications on the physical network segment.

It is composed of a 48-bit (or 6-byte) number, typically represented in hexadecimal format. While it's true that a MAC address uniquely identifies a specific device's network interface, it does not identify a local network, but rather a particular device or interface on a network.
