Question 10

An Ethernet switch has eight ports and all ports must be operational for 24 hours; from Monday
through Friday. However, a failure of Port 5 occurs as follows:

through Friday. However, a failure of Port 2 occurs on a particular week as follows:
Monday = 10 AM to 12 PM Wednesday = 4 PM to 9 PM Thursday = 4 PM to 7 PM
Friday = 3 PM to 6 PM Saturday = 9 AM to 1 PM
