Which of the following is an effective measure against a certain type of brute force password attack?

A.
Password used must not be a word found in a dictionary.

B.
Password history is used.

C.
Password reuse is not allowed.

D.
None of the choices.

Explanation:
Password reuse is not allowed (rotating passwords). Password history must be used to prevent users
from reusing passwords. On all systems with such a facility the last 12 passwords used will be kept in

the history. All computer system users must choose passwords that cannot be easily guessed.
Passwords used must not be a word found in a dictionary.
