A network operations team is assessing the reliability of various components in their data center. Which metric would BEST help them estimate the expected operational time between failures of a newly installed router?
Mean time between failures (MTBF) is the correct metric for estimating the time between potential failures for a piece of equipment or system under normal operation. MTBF offers vital insights into the reliability and expected operational lifespan of networking equipment, helping in proactive maintenance and disaster recovery planning. It does not measure the time to repair or recover from failures; those are aspects covered by other metrics like MTTR and RTO.
