RAID Level 2 :- The parity information is created using a hamming code that detects errors and establishes which part of which drive is in error. Source: KRUTZ, Ronald L. & VINES, Russel D., The CISSP Prep Guide: Mastering the Ten Domains of Computer Security, 2001, John Wiley & Sons, Page 66.

Cognitive passwords are fact or opinion-based information used to verify an individual's identity. Passwords that can be used only once are one-time or dynamic passwords. Password generators that use a challenge response scheme refer to token devices.
A passphrase is a sequence of characters that is longer than a password and is transformed into a virtual password.

Because a network-based IDS reviews packets and headers, denial of service
attacks can also be detected.
This question is an easy question if you go through the process of elimination. When you see an
answer containing the keyword: ALL It is something a give away that it is not the proper answer.
On the real exam you may encounter a few question where the use of the work ALL renders the
choice invalid. Pay close attention to such keyword.
The following are incorrect answers:
Even though most IDSs can detect some viruses and some password guessing attacks, they
cannot detect ALL viruses or ALL password guessing attacks. Therefore these two answers are
only detractors.
Unless the IDS knows the valid values for a certain dataset, it can NOT detect data corruption.

Archive bit 1 = On (the archive bit is set).
Archive bit 0 = Off (the archive bit is NOT set).
When the archive bit is set to ON, it indicates a file that has changed and needs to be backed up.
Differential backups backup all files changed since the last full. To do this, they don't change the
archive bit value when they backup a file. Instead the differential let's the full backup make that
change. An incremental only backs up data since the last incremental backup. Thus is does
change the archive bit from 1 (On) to 0 (Off).
The following answers are incorrect:
Backs up data labeled with archive bit 1 and changes the data label to archive bit 0. - This is the
behavior of an incremental backup, not a differential backup.
Backs up data labeled with archive bit 0 and leaves the data labeled as archive bit 0. - If the
archive bit is set to 0 (Off), it will only be backed up via a Full backup. Everything else will ignore it.
Backs up data labeled with archive bit 0 and changes the data label to archive bit 1. - If the archive bit is set to 0 (Off), it will only be backed up via a Full backup. Everything else will ignore it.
