Dell EMC Associate – Backup and Recovery Solutions Design v2 — Question 31

A computer has an MTBF of 7000 hours and an MTTR of 18 hours? What is the availability of the data?

Answer options

• A. 90.7%
• B. 99.1%
• C. 99.7%
• D. 99.8%

Correct answer: C

Explanation

The availability can be calculated using the formula: Availability = MTBF / (MTBF + MTTR). Plugging in the values, we get Availability = 7000 / (7000 + 18) = 99.7%. The other options represent incorrect calculations based on different interpretations of the MTBF and MTTR values.
