Every network device contains a unique built in Media Access Control (MAC) address, which is used to identify the authentic device to limit the network access. Which of the following addresses is a va

A3-07-B9-E3-BC-F9 contains exactly six octets of two hexadecimal digits each, separated by hyphens, which fully conforms to the IEEE 802 EUI-48 MAC address standard for a 48-bit hardware identifier. Every character falls within the valid hexadecimal range (0-9 and A-F), and the total length is the required 48 bits.

F936.28A1.5BCD.DEFA uses four groups of four hex digits totaling 64 bits, which exceeds the 48-bit MAC address length and does not match the IEEE 802 EUI-48 format.

1011-0011-1010-1110-1100-0001 is a binary representation of bits rather than hexadecimal octets, which is not a valid or recognized MAC address notation.

132.298.1.23 uses dotted-decimal notation resembling an IPv4 address, not hexadecimal pairs; additionally, the octet value 298 exceeds the maximum of 255, making it invalid in any standard addressing scheme.
