This question has to do with DC Functional Levels: 1. Name (or describe) a new feature that is dependent on Functional Levels that was added in Active Directory with Windows Server 2016. 2. If an organization cannot get one of their Child Domain DC's upgraded due to a scheduling problem with the local IT team, think about if the functionality you described above can still be implemented in their Parent Domain. Why or why not?3. Finally, name (or describe) a new feature that is dependent on Functional Levels that was added in Active Directory with Windows Server 2019. Hint: The information was presented to you in class, or you can look up online. Do ensure the feature you name or describe is dependent on Functional Levels!

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."
