You and other members of network engineers have teamed up to plan for the implementation of a military computer backbone network, which primarily makes use of fault-tolerant real-time systems. After deliberately planning, the team decided to use an optical data communication, specifically FDDI as the core network standard instead of ATM standard. Which one of the following could justify the implementation of FDDI?

FDDI's dual-ring environment adds pressure on real-time systems, and low-latency content such as audio and video

FDDI's dual-ring environment, optical bypass switch, and dual-homing support make FDDI a resilient media technology

ATM's optical bypass switch, and dual-homing support make FDDI a resilient media technology

ATMs cell-based data transfer is relatively small in that real-time systems, and low-latency content cannot cope up with the high-speed throughput

FDDI's cell-based data transfer allows sending of voice, audio and data over the same network without hogging the line

Explanation

FDDI's dual-ring environment, optical bypass switch, and dual-homing support make FDDI a resilient media technology. Dual-ring is the primary fault-tolerance of FDDI. If a station fails, the dual ring is automatically wrapped into a single ring, which lets data be transmitted on the FDDI ring without performance impact. The Optical Bypass Switch provides continues data transfer in case of a device failure. It uses internal mirrors to maintain the network instead of entering into a wrapped mode. The optical switch passes the light through itself by using the said internal mirrors. The Dual-homing feature is a fault-tolerant technique that provides additional redundancy by using two concentrators attached to the devices.
