4. leapYear. py (30) Write a program that asks the User to enter a year. The program should display the number of days in February that year. Use the following criteria to identify leap years: 1. Determine whether the year is divisible by 100. If it is, then it is a leap year and if only if it is also divisible by 400. For example, 2000 is a leap year but 2100 is not. 2. If the year is not divisible by 100, then it is a leap year and if only if it is also divisible by 4. For example, 2008 is a leap year but 2009 is not.

You are new to microsoft certification and want to start out by getting a certification geared around windows 8. what microsoft certification should you pursue?

You have a linux system that has a 1000gb hard disk drive, which has a 90gb partition containing an ext4 filesystem mounted to the / directory and a 4gb swap partition. currently, this linux system is only used by a few users for storing small files; however, the department manager wants to upgrade this system and use it to run a database application that will be used by 100 users. the database application and the associated data will take up over 200gb of hard disk space. in addition, these 100 users will store their personal files on the hard disk of the system. each user must have a maximum of 5gb of storage space. the department manager has made it very clear that this system must not exhibit any downtime as a result of hard disk errors. how much hard disk space will you require, and what partitions would you need to ensure that the system will perform as needed? where would these partitions be mounted? what quotas would you implement? what commands would you need to run and what entries to /etc/fstab would you need to create? justify your answers.
