171. Passwords should be:
A. assigned by the security administrator for first time logon.
B. changed every 30 days at the discretion of the user.
C. reused often to ensure the user does not forget the password.
D. displayed on the screen so that the user can ensure that it has
been entered properly.

The correct answer is:
A. assigned by the security administrator for first time logon.

Explanation:
Initial password assignment should be done discretely by the security
administrator. Passwords should be changed often (e.g., every 30
days); however, changing should not be voluntary, it should be
required by the system. Systems should not permit previous passwords
to be used again; old passwords may have been compromised and would
thus permit unauthorized access. Passwords should not be displayed in
any form.
