Dell EMC Associate – Information Storage and Management v5 — Question 59

A Fibre Channel switch has eight ports and all ports must be operational from 8 AM to 8 PM, Monday through Friday. However, a failure of Port 7 occurs in the week as follows:

Monday = 11 AM to 12 PM -

Wednesday = 4 PM to 9 PM -

Thursday = 4 AM to 9 AM -

Friday = 2 PM to 6 PM -

Saturday = 9 AM to 1 PM -

What is the availability of Port 7 in that week?

Answer options

Correct answer: C

Explanation

To calculate the availability of Port 7, we first determine the total operational hours in the week, which is 60 hours. The downtime for Port 7 sums up to 10 hours, resulting in an availability of (60 - 10) / 60 = 83.3%. The other options do not reflect the correct calculation based on the provided downtime.
