A MAC (Media Access Control) address is a unique identifier assigned to network interfaces for communications at the data link layer of a network segment. Key features of a MAC address include:
Length and Format: A MAC address is 48 bits in length, typically represented as 12 hexadecimal digits (e.g., 00:1A:2B:3C:4D:5E).
Hexadecimal Representation: The 12 hexadecimal digits are often grouped into pairs separated by colons or hyphens for readability (e.g., 00:1A:2B:3C:4D:5E or 00-1A-2B-3C-4D-5E).

The question is asking about a feature of a MAC address, not the total number of bits. I think option A is the correct answer here.

Okay, I know a MAC address is made up of 48 bits, so that narrows it down to either B or C. I'll go with B to be safe.

I hope the exam doesn't ask about the secret society code hidden in the MAC address. That would be a bit much.
