1. A database management system has an overall availability of 98.94%. How many minutes of downtime can be expected in a typical week (7 days), assuming uniform distribution of failures? Enter the number in minutes, rounded to the nearest whole number. 2. The data warehouse consists of a number of distinct components, including a cloud server (99.999% availability), a database management system server (99.4%), an analytics logic server (94.7%), and, of course, the network infrastructure to the cloud server, which has an availability of 99.9%. What is the overall availability of the system, expressed as a percentage with three digits of precision?
