Question

Which password characteristic can be required to eliminate LANMAN hash use and limit local authentication to NT on a modern Windows system?

A A maximum password length of 14 characters
B A minimum password length of 15 characters
C A minimum or 1 lowercase character
D A minimum of 1 uppercase character

Explanation

Windows generates both an LM hash and an NT hash when a password has fewer than 15 characters. A password of at least 15 characters prevents use of a usable LM hash for authentication, so NT hashing is used instead.
