Question No. 5

An Ethernet switch has eight ports and all ports must be operational for 24 hours from Monday through Friday.

However, a failure of Port 7 occurs as follows:

Monday=4 PM to 11 PM

Wednesday= 2 PM to 10 PM

Friday= 5 AM to11 AM

What is the MTTR of Port 7?

Show Answer Hide Answer
Correct Answer: C

To calculate MTTR, we need to convert the hours into minutes. Here are the steps:

Monday: Port 7 was down from 4 PM to 11 PM. That's 7 hours or 420 minutes.

Wednesday: Port 7 was down from 2 PM to 10 PM. That's 8 hours or 480 minutes.

Friday: Port 7 was down from 5 AM to11 AM. That's 6 hours or 360 minutes.

Total corrective maintenance time = 420 + 480 + 360 =1260 minutes

Number of repairs =3

MTTR = Total corrective maintenance time / Number of repairs

MTTR =1260 / 3 =420 minutes

Therefore, the MTTR of Port 7 is420 minutes.
