Companies can set predefined thresholds for the number of certain types of errors that will be allowed before the activity is considered suspicious. The threshold is a baseline for violation activities that may be normal for a user to commit before alarms are raised. This baseline is referred to as a clipping level.
The following are incorrect answers: Clipping levels enable a security administrator to customize the audit trail to record only those violations which are deemed to be security relevant. This is not the best answer, you would not record ONLY security relevant violations, all violations would be recorded as well as all actions performed by authorized users which may not trigger a violation. This could allow you to indentify abnormal activities or fraud after the fact.
Clipping levels enable the security administrator to customize the audit trail to record only actions for users with access to user accounts with a privileged status. It could record all
security violations whether the user is a normal user or a privileged user.
Clipping levels enable a security administrator to view all reductions in security levels which
have been made to user accounts which have incurred violations. The keyword "ALL"
makes this question wrong. It may detect SOME but not all of violations. For example,
application level attacks may not be detected.

As a signal travels though a medium, it attenuates (loses strength) and at some point will become indistinguishable from noise. To assure trouble-free communication, maximum cable lengths are set between nodes to assure that attenuation will not cause a problem. The maximum CAT-5 UTP cable length between two nodes for 10BASE-T is 100M.
The following answers are incorrect:
80 meters. It is only a distracter.
185 meters. Is incorrect because it is the maximum length for 10Base-2 500 meters. Is incorrect because it is the maximum length for 10Base-5

Static translation (also called port forwarding), assigns a fixed address to a
specific internal network resource (usually a server).
Static NAT is required to make internal hosts available for connection from external hosts.
It merely replaces port information on a one-to-one basis. This affords no protection to
statistically translated hosts: hacking attacks will be just as efficiently translated as any
other valid connection attempt.
NOTE FROM CLEMENT:
Hiding Nat or Overloaded Nat is when you have a group of users behind a unique public IP
address. This will provide you with some security through obscurity where an attacker
scanning your network would see the unique IP address on the outside of the gateway but
could not tell if there is one user, ten users, or hundreds of users behind that IP.
NAT was NEVER built as a security mechanism.
In the case of Static NAT used for some of your servers for example, your web server
private IP is map to a valid external public IP on a one on one basis, your SMTP server
private IP is mapped to a static public IP, and so on.
If an attacker scan the IP address range on the external side of the gateway he would
discover every single one of your servers or any other hosts using static natting. Ports that
are open, services that are listening, and all of this info could be gathered just as if the
server was in fact using a public IP. It does not provide this security through obscurity
mentioned above.
All of the other answer are incorrect.

The percentage of valid subjects that are falsely rejected is called the False Rejection Rate (FRR) or Type I Error.

Explanation/Reference:
Capacitance detectors monitor an electrical field surrounding the object being monitored. They are used for spot protection within a few inches of the object, rather than for overall room security monitoring used by wave detectors. Penetration of this field changes the electrical capacitance of the field enough to generate and alarm. Wave pattern motion detectors generate a frequency wave pattern and send an alarm if the pattern is disturbed as it is reflected back to its receiver. Field-powered devices are a type of personnel access control devices. Audio detectors simply monitor a room for any abnormal sound wave generation and trigger an alarm.
