Question 7

A cloud provider is deploying a new SaaS product comprised of a cloud service. As part of the deployment, the cloud provider wants to publish a service level agreement (SLA) that provides an availability rating based on its estimated availability over the next 12 months. First, the cloud provider estimates that, based on historical data of the cloud environment, there is a 30% chance that the physical server hosting the cloud service will crash and that such a crash would result in 2 days of downtime before the cloud service could be restored. It is further estimated that there is a 100% chance that, over the course of the 12 month period, there will be various attacks on the cloud service, resulting in a total of 60 hours of additional downtime. Based on these estimates, the availability that needs to be published in the SLA is ___________________ (rounded to one decimal).Select the correct answer.
