Which type of password provides maximum security because a new password is required for each new log-on?

A.
One-time or dynamic password

B.
Cognitive password

C.
Static password

D.
Passphrase

Explanation:
A one-time or dynamic password is no longer valid and, if obtained by a hacker, cannot be reused after it has
been used. A one-time or dynamic password is used in environments where a higher level of security than
static passwords is required.
Incorrect Answers:
B: After a user is enrolled by answering several questions based on her life experiences, the user can answer
the questions asked of her to be authenticated instead of having to remember a password. The questions do
not change from log-on to log-on.
C: Static passwords are passwords that can be reused, but may or may not expire.
D: Passphrases are long static passwords, which is made up of words in a phrase or sentence.
