Question ID:PT86 S4 Q20 Passage:Coming up with secure passwords for confidential computer files is difficult. Users prefer passwords that are easy to remember, such as birth dates or relatives' names. Unfortunately, these are the easiest to guess for an outsider who wants to gain access to valuable information. Random configurations of letters and numbers are the hardest to guess, but these are also the easiest for legitimate users to forget. Users who forget their passwords use up the system administrator's time; furthermore, passwords that are very difficult to remember are generally written down by users, and hence pose the greatest security threat of all.

Choice C:Passwords that are very easy to guess pose less of a security threat than passwords that are very difficult to remember. Choice D:Passwords that are random configurations of letters and numbers are the least likely to result in security breaches. Choice E:The easier a password is to remember, the more secure the computer account.
