QUESTION 84
Which of the following is a technique for gathering information about a remote network protected by a firewall?

 Firewalking

 Warchalking

 Wardriving

 Wardialing

Explanation
Explanation:
Fire walking is a technique for gathering information about a remote network protected by a firewall. This technique can be used effectively to perform information gathering attacks. In this technique, an attacker sends a crafted packet with a TTL value that is set to expire one hop past the firewall. If the firewall allows this crafted packet through, it forwards the packet to the next hop. On the next hop, the packet expires and elicits an ICMP
“TTL expired in transit” message to the attacker. If the firewall does not allow the traffic, there should be no response, or an ICMP “administratively prohibited” message should be returned to the attacker. A malicious attacker can use firewalking to determine the types of ports/protocols that can bypass the firewall. To use firewalking, the attacker needs the IP address of the last known gateway before the firewall and the IP address of a host located behind the firewall. The main drawback of this technique is that if an administrator blocks ICMP packets from leaving the network, it is ineffective.
Answer option B 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 C is incorrect. War driving, also called access point mapping, is the act of locating and possibly exploiting connections to wireless local area networks while driving around a city or elsewhere. To do war driving, one needs a vehicle, a computer (which can be a laptop), a wireless Ethernet card set to work in promiscuous mode, and some kind of an antenna which can be mounted on top of or positioned inside the car.
Because a wireless LAN may have a range that extends beyond an office building, an outside user may be able to intrude into the network, obtain a free Internet connection, and possibly gain access to company records and other resources.
Answer option D is incorrect. War dialing or wardialing 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, Bulletin board 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.

QUESTION 85
Which of the following analyzes network traffic to trace specific transactions and can intercept and log traffic passing over a digital network? Each correct answer represents a complete solution. Choose all that apply.

 Wireless sniffer

 Spectrum analyzer

 Protocol analyzer

 Performance Monitor

Protocol analyzer (also known as a network analyzer, packet analyzer or sniffer, or for particular types of networks, an Ethernet sniffer or wireless sniffer) is computer software or computer hardware that can intercept and log traffic passing over a digital network. As data streams flow across the network, the sniffer captures each packet and, if needed, decodes and analyzes its content according to the appropriate RFC or other specifications.
Answer option D is incorrect. Performance Monitor is used to get statistical information about the hardware and software components of a server.
Answer option B is incorrect. A spectrum analyzer, or spectral analyzer, is a device that is used to examine the spectral composition of an electrical, acoustic, or optical waveform. It may also measure the power spectrum.

QUESTION 86
Identify the correct statements regarding a DMZ zone:

 It is a file integrity monitoring mechanism

 It is a Neutral zone between a trusted network and an untrusted network

 It serves as a proxy

 It includes sensitive internal servers such as database servers

QUESTION 87
What is the range for well known ports?

 49152 through 65535

 1024 through 49151

 Above 65535

 0 through 1023

QUESTION 88
Which of the following techniques is used for drawing symbols in public places for advertising an open Wi-Fi
wireless network?

 Spamming

 War driving

 War dialing

 Warchalking

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 B is incorrect. War driving, also called access point mapping, is the act of locating and possibly
exploiting connections to wireless local area networks while driving around a city or elsewhere. To do war
driving, one needs a vehicle, a computer (which can be a laptop), a wireless Ethernet card set to work in
promiscuous mode, and some kind of an antenna which can be mounted on top of or positioned inside the car.
Because a wireless LAN may have a range that extends beyond an office building, an outside user may be
able to intrude into the network, obtain a free Internet connection, and possibly gain access to company
records and other resources.
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. Spamming is the technique of flooding the Internet with a number of copies of the
same message. The most widely recognized form of spams are e-mail spam, instant messaging spam, Usenet
newsgroup spam, Web search engine spam, spam in blogs, online classified ads spam, mobile phone
messaging spam, Internet forum spam, junk fax transmissions, social networking spam, television advertising
and file sharing network spam.

 Dry Chemical

QUESTION 91
Which of the following is a computer networking protocol used by hosts to retrieve IP address assignments and other configuration information?

 SNMP

 ARP

 DHCP

 Telnet

The Dynamic Host Configuration Protocol (DHCP) is a computer networking protocol used by hosts (DHCP clients) to retrieve IP address assignments and other configuration information. DHCP uses a client-server architecture. The client sends a broadcast request for configuration information. The DHCP server receives the request and responds with configuration information from its configuration database. In the absence of DHCP, all hosts on a network must be manually configured individually – a time-consuming and often error-prone undertaking. DHCP is popular with ISP’s because it allows a host to obtain a temporary IP address. Answer option B is incorrect. Address Resolution Protocol (ARP) is a network maintenance protocol of the TCP/IP protocol suite. It is responsible for the resolution of IP addresses to media access control (MAC) addresses of a network interface card (NIC). The ARP cache is used to maintain a correlation between a MAC address and its corresponding IP address. ARP provides the protocol rules for making this correlation and providing address conversion in both directions. ARP is limited to physical network systems that support broadcast packets. Answer option A is incorrect. The Simple Network Management Protocol (SNMP) allows a monitored device (for example, a router or a switch) to run an SNMP agent. This protocol is used for managing many network devices remotely. When a monitored device runs an SNMP agent, an SNMP server can then query the SNMP agent running on the device to collect information such as utilization statistics or device configuration information. An SNMP-managed network typically consists of three components: managed devices, agents, and one or more network management systems. Answer option D is incorrect. Telnet (Telecommunication network) is a network protocol used on the Internet or local area networks to provide a bidirectional interactive communications facility. Typically, Telnet provides access to a command-line interface on a remote host via a virtual terminal connection which consists of an 8-bit byte oriented data connection over the Transmission Control Protocol (TCP). User data is interspersed in-band with TELNET control information. Typically, the Telnet protocol is used to establish a connection to Transmission Control Protocol (TCP) port number 23.
