Question

In a SLA negotiation, provider agreed with the service availability 98%. Consumer runs the application for X hours/day. At the end of one month [31 days], it was found that total service outage is 12 hrs. However, SLA negotiation (in terms of service availability) is honored.
a. X is atleast 19.74
b. X is atmost 19.74
c. X is exactly 19.74
d. Insufficient information

Answer 1

Answer :- B

Service Outage time per month [31 days] - 12 hrs

So, 12 hrs is 2% of downtime. So uptime will be 98%, It will be 12/2 x 98 = 588 hours

Assuming he runs the application equal number of hrs per day.

Total time when application was attempted = Time application was up + Time application was down

Total time when application was attempted = 588 + 12 = 600

Time application run per day = 600 / 31 = 19.35 Hrs/day

So the answer is b. X is atmost 19.74
