Explanation:
Fiber Distributed Data Interface (FDDI) is a high-speed token-passing
technology that offers transmission speeds of 100 Mbps. It is used as a metropolitan
area network (MAN) technology, meaning it connects different networks together.
(FDDI can be used as a LAN technology, but the CISSP exam refers to it mainly as a
MAN technology.)
