Which statements about reliability measurement are TRUE? (Multiple Choice)

  1. Generally, system reliability is determined by mean time between failure (MTBF) and mean time to repair (MTTR).
  2. MTBF refers to the average time (usually expressed in hours) from the fault occurrence time to the fault recovery time. A larger MTBF indicates a higher reliability.
  3. MTTR refers to the average time from the fault occurrence time to the fault recovery time.
  4. The formula for calculating the MTTR is as follows:
    MTTR= Fault detection time + Hardware replacement time + System initialization time + Link recovery time + Route convergence time + Forwarding recovery time A smaller MTTR indicates a higher reliability.
