Question is from Performance Management Tradeoffs topic in division Technology Tradeoffs in Software Defined Radio of Cognitive Radio

Answer 1

Correct answer is (b) less than 0.5

Best explanation: Good performance is observed when utilization is less than 0.5. There is 50% available capacity. The unprecedented performance degradation generally causes utilization to fall in the range between 0.5 – 0.75. When utilization is greater than 0.75, the system is regarded as unstable.
