QUESTION: 26

FILL BLANK
Fill in the blank with the appropriate term. A________________ network is a local area network (LAN) in which all computers are connected in a ring or star topology and a bit- or token-passing scheme is used for preventing the collision of data between two computers that want to send messages at the same time.

Token Ring

Answer(s): A

Explanation:

A Token Ring network is a local area network (LAN) in which all computers are connected in a ring or star topology and a bit- or token-passing scheme is used in order to prevent the collision of data between two computers that want to send messages at the same time. The Token Ring protocol is the second most widely- used protocol on local area networks after Ethernet. The IBM Token Ring protocol led to a standard version, specified as IEEE 802.5. Both protocols are used and are very similar. The IEEE 802.5 Token Ring technology provides for data transfer rates of either 4 or 16 megabits per second.
Working:
Empty information frames are constantly circulated on the ring. When a computer has a message to send, it adds a token to an empty frame and adds a message and a destination identifier to the frame. The frame is then observed by each successive workstation. If the workstation sees that it is the destination for the message, it copies the message from the frame and modifies the token back to 0. When the frame gets back to the originator, it sees that the token has been modified to 0 and that the message has been copied and received. It removes the message from the particular frame. The frame continues to circulate as an empty frame, ready to be taken by a workstation when it has a message to send.

QUESTION: 27

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

Answer(s): D

Explanation:

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.

QUESTION: 28

Which of the following is a standard protocol for interfacing external application software with an information server, commonly a Web server?

DHCP
IP
CGI
TCP

Answer(s): C

Explanation:

The Common Gateway Interface (CGI) is a standard protocol for interfacing external application software with an information server, commonly a Web server. The task of such an information server is to respond to requests (in the case of web servers, requests from client web browsers) by returning output. When a user requests the name of an entry, the server will retrieve the source of that entry's page (if one exists), transform it into HTML, and send the result.
Answer option A is incorrect. DHCP is a Dynamic Host Configuration Protocol that allocates unique (IP) addresses dynamically so that they can be used when no longer needed. A DHCP server is set up in a DHCP environment with the appropriate configuration parameters for the given network. The key parameters include the range or "pool" of available IP addresses, correct subnet masks, gateway, and name server addresses.
Answer option B is incorrect. The Internet Protocol (IP) is a protocol used for communicating data across a packet-switched inter-network using the Internet Protocol Suite, also referred to as TCP/IP.IP is the primary protocol in the Internet Layer of the Internet Protocol Suite and has the task of delivering distinguished protocol datagrams (packets) from the source host to the destination host solely based on their addresses. For this purpose, the Internet Protocol defines addressing methods and structures for datagram encapsulation. The first major version of addressing structure, now referred to as Internet Protocol Version 4 (IPv4), is still the dominant protocol of the Internet, although the successor, Internet Protocol Version 6 (IPv6), is being deployed actively worldwide.
Answer option D is incorrect. Transmission Control Protocol (TCP) is a reliable, connection-oriented protocol operating at the transport layer of the OSI model. It provides a reliable packet delivery service encapsulated within the Internet Protocol (IP). TCP guarantees the delivery of packets, ensures proper sequencing of data, and provides a checksum feature that validates both the packet header and its data for accuracy. If the network corrupts or loses a TCP packet during transmission, TCP is responsible for retransmitting the faulty packet. It can transmit large amounts of data. Application layer protocols, such as HTTP and FTP, utilize the services of TCP to transfer files between clients and servers.

QUESTION: 29

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?

High-interaction honeypot
Medium-interaction honeypot
Honeyd
Low-interaction honeypot

Answer(s): A

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.
