43:  

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 :

A.	96.3%
B.	97.3%
C.	98.3%
D.	99.3%
	Answer Report Discuss
	Option: C Explanation :   Availability = Uptime/(Uptime + Downtime)   Here Uptime = 30 *24= 720 hr  Downtime = 12 hrs Availability =720/(720+12)   =98.3% Click on Discuss to view users comments. Write your comments here: Updating your Comments.. Updating your Comments..
