The power in the company's office is not always reliable, Kyle needs to make sure the servers do not go down or are without power for too long. Kyle decides to purchase an Uninterruptible Power Supply (UPS) that has a pair of inverters and converters to charge the battery and provides power when needed. What type of UPS has Kyle purchased?

This ensures that there is zero transfer time to the battery when power is lost, providing the most reliable power for sensitive equipment and critical applications that cannot tolerate any interruption in power. Kyle's choice of a True Online UPS is appropriate for ensuring that the servers, which store confidential data and run applications, are not affected by unreliable power sources.

NEW QUESTION # 19
Daniel works as a network administrator in an Information Security company. He has just deployed an IDS in his organization's network and wants to calculate the false positive rate for his implementation. Which of the following formulae can he use to so?

  • A. False Negative/False Negative+True Positive
  • B. False Negative/True Negative+True positive
  • C. False Positive/False Positive+True Negative
  • D. True Negative/False Negative+True Positive

Answer: C

Explanation:
The false positive rate is a measure used to evaluate the performance of an IDS (Intrusion Detection System).
It is calculated by dividing the number of false positives (FP) by the sum of false positives and true negatives (TN). The formula is:
False Positive Rate=FP+TNFP
This formula helps in determining how often the IDS incorrectly classifies an event as a threat, which is actually benign. A lower false positive rate indicates a more accurate IDS.
References: This formula and its application are consistent with standard practices in network security and align with the Certified Network Defender (CND) course material. For further details, please refer to the official CND study guide and documents.

NEW QUESTION # 21
Which of the following can be performed with software or hardware devices in order to record everything a
person types using his or her keyboard?

  • A. War dialing
  • B. Warchalking
  • C. IRC bot
  • D. Keystroke logging

Answer: D

Explanation:
Keystroke logging is a method of logging and recording user keystrokes. It can be performed with software or
hardware devices. Keystroke logging devices can record everything a person types using his or her keyboard,
such as to measure employee's productivity on certain clerical tasks. These types of devices can also be used
to get usernames, passwords, etc.
Answer option C is incorrect. War dialing is a technique of using a modem to automatically scan a list of
telephone numbers, usually dialing every number in a local area code to search for computers, BBS systems,
and fax machines. Hackers use the resulting lists for various purposes, hobbyists for exploration, and crackers
(hackers that specialize in computer security) for password guessing.
Answer option A is incorrect. Warchalking is the drawing of symbols in public places to advertise an open Wi-Fi
wireless network. Having found a Wi-Fi node, the warchalker draws a special symbol on a nearby object, such
as a wall, the pavement, or a lamp post. The name warchalking is derived from the cracker terms war dialing
and war driving.
Answer option D is incorrect. An Internet Relay Chat (IRC) bot is a set of scripts or an independent program
that connects to Internet Relay Chat as a client, and so appears to other IRC users as another user. An IRC
bot differs from a regular client in that instead of providing interactive access to IRC for a human user, it
performs automated functions.
