An administrator discovers that many users have used their same passwords for years even though the
network requires that the passwords be changed every six weeks. Which of the following, when used together,
would BEST prevent users from reusing their existing password? (Choose two.)
Length of password
Minimum password age
In this question, users are forced to change their passwords every six weeks. However, they are able to change
their password and enter the same password as the new password.Password history determines the number of previous passwords that cannot be used when a user changes his
password. For example, a password history value of 5 would disallow a user from changing his password to any
of his previous 5 passwords.
When a user is forced to change his password due to a maximum password age period expiring, (the question
states that the network requires that the passwords be changed every six weeks) he could change his
password to a previously used password. Or if a password history value of 5 is configured, the user could
change his password six times to cycle back round to his original password. This is where the minimum
password age comes in. This is the period that a password must be used for. For example, a minimum
password age of 30 would determine that when a user changes his password, he must continue to use the
same password for at least 30 days.
