IT Service Management Foundation Practice Test

Answer: B - The role of Availability Management with Incident Management is to minimize the duration and effect of incidents.

Key Takeaway: When an incident occurs Availability Management must ensure the business operations are brought up and functional as soon as possible. There are several Availability Management metrics: mean time between failures (MTBF); mean time to restore service (MTRS); and mean time between system incidents (MTBSI). If there are is a high ratio between MTBF to MTBSI it means there are a lot of small issues whereas a low ratio between MTBF and MTBSI means there just a few major issues.
