Nisha Mittal
A server crashes on the average once in 30 days, that is, the Mean Time Between Failures (MTBF) is 30 days. When this happens, it takes 12 hours to reboot it, that is, the Mean Time to Repair (MTTR) is 12 hours. The availability of server with these reliability data values is approximately : (1) 96.3% (2) 97.3% (3) 98.3% (4) 99.3%
