Question:
How is an EUI-64 format interface ID created from a 48-bit MAC address?
- by appending 0xFF to the MAC address
- by prefixing the MAC address with 0xFFEE
- by prefixing the MAC address with 0xFF and appending 0xFF to it
- by inserting 0xFFFE between the upper three bytes and the lower three bytes of the MAC address
- by prefixing the MAC address with 0xF and inserting 0xF after each of its first three bytes
Explanation: The modified EUI-64 format interface identifier is derived from the 48-bit link-layer (MAC) address by inserting the hexadecimal number FFFE between the upper three bytes (OUI field) and the lower three bytes (serial number) of the link layer address.
