問題文
A compliance requirement states that passwords must expire after 90 days and users must be warned 7 days in advance. New accounts should inherit this automatically. Where is that default set?
選択肢
- In the login definitions file, whose maximum-days and warning-age settings are applied to accounts created after the change.
- In the aging fields of each existing account, since changing them there propagates the value to accounts created later, and the defaults for new accounts are read from those fields.
- In the authentication module stack, because the stack is consulted at account creation time and copies its password policy settings into the aging fields of the new account, which is why editing the stack is the only way to change the default for future accounts.
- In the shadow file's header, which carries the site-wide defaults.
