NEW QUESTION 103
Which of the following cables is made of glass or plastic and transmits signals in the form of light?
- A. Twisted pair cable
- B. Plenum cable
- C. Coaxial cable
- D. Fiber optic cable
Answer: D
Explanation:
Fiber optic cable is also known as optical fiber. It is made of glass or plastic and transmits signals in the form of
light. It is of cylindrical shape and consists of three concentric sections: the core, the cladding, and the jacket.
Optical fiber carries much more information than conventional copper wire and is in general not subject to
electromagnetic interference and the need to retransmit signals. Most telephone company's long-distance lines
are now made of optical fiber. Transmission over an optical fiber cable requires repeaters at distance intervals.
The glass fiber requires more protection within an outer cable than copper.
Answer option B is incorrect. Twisted pair cabling is a type of wiring in which two conductors (the forward and
return conductors of a single circuit) are twisted together for the purposes of canceling out electromagnetic
interference (EMI) from external sources. It consists of the following twisted pair cables:
Shielded Twisted Pair: Shielded Twisted Pair (STP) is a special kind of copper telephone wiring used in some
business installations. An outer covering or shield is added to the ordinary twisted pair telephone wires; the
shield functions as a ground. Twisted pair is the ordinary copper wire that connects home and many business
computers to the telephone company. Shielded twisted pair is often used in business installations. Unshielded
Twisted Pair: Unshielded Twisted Pair (UTP) is the ordinary wire used in home. UTP cable is also the most
common cable used in computer networking. Ethernet, the most common data networking standard, utilizes
UTP cables. Twisted pair cabling is often used in data networks for short and medium length connections
because of its relatively lower costs compared to optical fiber and coaxial cable.UTP is also finding increasing
use in video applications, primarily in security cameras. Many middle to high-end cameras include a UTP
output with setscrew terminals. This is made possible by the fact that UTP cable bandwidth has improved to
match the baseband of television signals.
Answer option A is incorrect. Coaxial cable is the kind of copper cable used by cable TV companies between
the community antenna and user homes and businesses. Coaxial cable is sometimes used by telephone
companies from their central office to the telephone poles near users. It is also widely installed for use in
business and corporation Ethernet and other types of local area network. Coaxial cable is called "coaxial"
because it includes one physical channel that carries the signal surrounded (after a layer of insulation) by
another concentric physical channel, both running along the same axis. The outer channel serves as a ground.
Many of these cables or pairs of coaxial tubes can be placed in a single outer sheathing and, with repeaters,
can carry information for a great distance. It is shown in the figure below:
Answer option C is incorrect. Plenum cable is cable that is laid in the plenum spaces of buildings. The plenum
is the space that can facilitate air circulation for heating and air conditioning systems, by providing pathways for
either heated/conditioned or return airflows. Space between the structural ceiling and the dropped ceiling or
under a raised floor is typically considered plenum. However, some drop ceiling designs create a tight seal that
does not allow for airflow and therefore may not be considered a plenum air-handling space. The plenum
space is typically used to house the communication cables for the building's computer and telephone network.
NEW QUESTION 104
Which of the following is a software tool used in passive attacks for capturing network traffic?
- A. Intrusion prevention system
- B. Intrusion detection system
- C. Warchalking
- D. Sniffer
Answer: D
Explanation:
A sniffer is a software tool that is used to capture any network traffic. Since a sniffer changes the NIC of the
LAN card into promiscuous mode, the NIC begins to record incoming and outgoing data traffic across the
network. A sniffer attack is a passive attack because the attacker does not directly connect with the target host.
This attack is most often used to grab logins and passwords from network traffic. Tools such as Ethereal,
Snort, Windump, EtherPeek, Dsniff are some good examples of sniffers. These tools provide many facilities to
users such as graphical user interface, traffic statistics graph, multiple sessions tracking, etc.
Answer option C is incorrect. An intrusion prevention system (IPS) is a network security device that monitors
network and/or system activities for malicious or unwanted behavior and can react, in real-time, to block or
prevent those activities. When an attack is detected, it can drop the offending packets while still allowing all
other traffic to pass.
Answer option B is incorrect. An IDS (Intrusion Detection System) is a device or software application that
monitors network and/or system activities for malicious activities or policy violations and produces reports to a
Management Station. Intrusion prevention is the process of performing intrusion detection and attempting to
stop detected possible incidents. Intrusion detection and prevention systems (IDPS) are primarily focused on
identifying possible incidents, logging information about them, attempting to stop them, and reporting them to
security administrators.
Answer option D 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.
NEW QUESTION 105

FILL BLANK
Fill in the blank with the appropriate term. In computing, ______________ is a class of data storage devices
that read their data in sequence.
Answer:
Explanation:
SAM
Explanation:
In computing, sequential access memory (SAM) is a class of data storage devices that read their data in
sequence. This is in contrast to random access memory (RAM) where data can be accessed in any order.
Sequential access devices are usually a form of magnetic memory. While sequential access memory is read in
sequence, access can still be made to arbitrary locations by "seeking" to the requested location. Magnetic
sequential access memory is typically used for secondary storage in general-purpose computers due to their
higher density at lower cost compared to RAM, as well as resistance to wear and non-volatility. Examples of
SAM devices include hard disks, CD-ROMs, and magnetic tapes.

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. Warchalking
- B. Keystroke logging
- C. IRC bot
- D. War dialing
Answer: B
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.
NEW QUESTION 111
Which of the following honeypots provides an attacker access to the real operating system without any restriction and collects a vast amount of information about the attacker?
- A. Low-interaction honeypot
- B. High-interaction honeypot
- C. Honeyd
- D. Medium-interaction honeypot
Answer: B
Explanation:
A high-interaction honeypot offers a vast amount of information about attackers. It provides an attacker access to the real operating system without any restriction. A high-interaction honeypot is a powerful weapon that provides opportunities to discover new tools, to identify new vulnerabilities in the operating system, and to learn how blackhats communicate with one another.
Answer option D is incorrect. A low-interaction honeypot captures limited amounts of information that are mainly transactional data and some limited interactive information. Because of simple design and basic functionality, low-interaction honeypots are easy to install, deploy, maintain, and configure. A low-interaction honeypot detects unauthorized scans or unauthorized connection attempts. A low-interaction honeypot is like a one-way connection, as the honeypot provides services that are limited to listening ports. Its role is very passive and does not alter any traffic. It generates logs or alerts when incoming packets match their patterns.
Answer option B is incorrect. A medium-interaction honeypot offers richer interaction capabilities than a low- interaction honeypot, but does not provide any real underlying operating system target. Installing and configuring a medium-interaction honeypot takes more time than a low-interaction honeypot. It is also more complicated to deploy and maintain as compared to a low-interaction honeypot. A medium-interaction honeypot captures a greater amount of information but comes with greater risk. Answer option C is incorrect. Honeyd is an example of a low-interaction honeypot.

Which of the following tools is an open source protocol analyzer that can capture traffic in real time?
- A. Wireshark
- B. NetWitness
- C. None
- D. NetResident
- E. Bridle
Answer: A
Explanation:
Wireshark is an open source protocol analyzer that can capture traffic in real time. Wireshark is a free packet sniffer computer application. It is used for network troubleshooting, analysis, software and communications protocol development, and education. Wireshark is very similar to tcpdump, but it has a graphical front-end, and many more information sorting and filtering options. It allows the user to see all traffic being passed over the network (usually an Ethernet network but support is being added for others) by putting the network interface into promiscuous mode.
Wireshark uses pcap to capture packets, so it can only capture the packets on the networks supported by pcap. It has the following features:
Data can be captured "from the wire" from a live network connection or read from a file that records the already-captured packets.
Live data can be read from a number of types of network, including Ethernet, IEEE 802.11, PPP, and loopback.
Captured network data can be browsed via a GUI, or via the terminal (command line) version of the utility, tshark.
Captured files can be programmatically edited or converted via command-line switches to the "editcap" program.
Data display can be refined using a display filter. Plugins can be created for dissecting new protocols.
Answer option C is incorrect. Snort is an open source network intrusion prevention and detection system that operates as a network sniffer. It logs activities of the network that is matched with the predefined signatures.
Signatures can be designed for a wide range of traffic, including Internet Protocol (IP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Internet Control Message Protocol (ICMP).
Answer option D is incorrect. NetWitness is used to analyze and monitor the network traffic and activity.
Answer option A is incorrect. Netresident is used to capture, store, analyze, and reconstruct network events and activities.
