Chapter 2 Page 26 in ebook, varies based on font size. But in the description for Figure 2.5 "You can choose to do an upgrade only when you have a previous version of Windows Server 2008 R2 to upgrade."
I believe this part of the book was not revised to the current R2 release because with R2 you should be able to upgrade Windows Server 2012.
Chapter 2 Page 29 Figure 2.10 "A complex password is required comprised of eight or more characters with a mix of Uppercase and lowercase letter and numbers."
I believe this is only 7 which I agree should be eight. Also it will accept One upper case and/or a special character. Although not server this is taken from Windows 10 Local Security Policy.
Not contain the user's account name or parts of the user's full name that exceed two consecutive characters
Be at least six characters in length
Contain characters from three of the following four categories:
English uppercase characters (A through Z)
English lowercase characters (a through z)
Base 10 digits (0 through 9)
Non-alphabetic characters (for example, !, $, #, %)
Complexity requirements are enforced when passwords are changed or created.
I will test tonight in my VM lab.
Verified only requires 7 characters.
