SONET's extraordinary ____ results from its use of a double-ring topology over fiber-optic cable.
A) throughput
B) low cost
C) fault tolerance
D) latency

Question

Quizplus · Accepted Answer

SONET's fault tolerance is achieved through its use of a double-ring topology, which provides redundancy and automatic restoration in the event of a fiber cut or equipment failure. Throughput and latency are also important factors in SONET performance, but they are not directly related to the double-ring topology. Low cost is not typically associated with SONET, as it is a high-speed, high-capacity networking technology that requires significant investment in fiber-optic infrastructure.
