CORRECT TEXT
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.
Answer:
Explanation:
Token Ring
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.

Which of the following is the practice of sending unwanted e-mail messages, frequently with commercial
content, in large quantities to an indiscriminate set of recipients? Each correct answer represents a complete
solution. Choose all that apply.
- A. E-mail spam
- B. Junk mail
- C. Email spoofing
- D. Email jamming
Answer: A,B
Explanation:
E-mail spam, also known as unsolicited bulk email (UBE), junk mail, or unsolicited commercial email (UCE), is
the practice of sending unwanted e-mail messages, frequently with commercial content, in large quantities to
an indiscriminate set of recipients.
Answer option A is incorrect. Email spoofing is a fraudulent email activity in which the sender address and
other parts of the email header are altered to appear as though the email originated from a different source.
Email spoofing is a technique commonly used in spam and phishing emails to hide the origin of the email
message. By changing certain properties of the email, such as the From, Return-Path and Reply-To fields
(which can be found in the message header), ill-intentioned users can make the email appear to be from
someone other than the actual sender. The result is that, although the email appears to come from the address
indicated in the From field (found in the email headers), it actually comes from another source.
Answer option D is incorrect. Email jamming is the use of sensitive words in e-mails to jam the authorities that
listen in on them by providing a form of a red herring and an intentional annoyance. In this attack, an attacker
deliberately includes "sensitive" words and phrases in otherwise innocuous emails to ensure that these are
picked up by the monitoring systems. As a result, the senders of these emails will eventually be added to a
"harmless" list and their emails will be no longer intercepted, hence it will allow them to regain some privacy.

- A. False message
- B. Message modification
- C. Eavesdropping
- D. Message replay
- E. Identity theft
- F. Message repudiation
- G. Message digest
Answer: A,B,C,D,E,F
Explanation:
Following are the common security problems involved in communications and email:
Eavesdropping: It is the act of secretly listening to private information through telephone lines, e-
mail, instant messaging, and any other method of communication considered private.
Identity theft: It is the act of obtaining someone's username and password to access his/her email
servers for reading email and sending false email messages. These credentials can be obtained
by eavesdropping on SMTP, POP, IMAP, or Webmail connections.
Message modification: The person who has system administrator permission on any of the SMTP
servers can visit anyone's message and can delete or change the message before it continues on
to its destination. The recipient has no way of telling that the email message has been altered.
False message: It the act of constructing messages that appear to be sent by someone else.
Message replay: In a message replay, messages are modified, saved, and re-sent later.
Message repudiation: In message repudiation, normal email messages can be forged. There is no
way for the receiver to prove that someone had sent him/her a particular message. This means
that even if someone has sent a message, he/she can successfully deny it.
Answer option D is incorrect. A message digest is a number that is created algorithmically from a
file and represents that file uniquely.
NEW QUESTION 70
Which of the following is a software tool used in passive attacks for capturing network traffic?
- A. Warchalking
- B. Sniffer
- C. Intrusion detection system
- D. Intrusion prevention system
Answer: B
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 A 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 C 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.

Which of the following is a network that supports mobile communications across an arbitrary number of wireless LANs and satellite coverage areas?
- A. HAN
- B. GAN
- C. WAN
- D. LAN
Answer: B
Explanation:
A global area network (GAN) is a network that is used for supporting mobile communications across an arbitrary number of wireless LANs, satellite coverage areas, etc. The key challenge in mobile communications is handing off the user communications from one local coverage area to the next. Answer option B is incorrect. A wide area network (WAN) is a geographically dispersed telecommunications network. The term distinguishes a broader telecommunication structure from a local area network (LAN). A wide area network may be privately owned or rented, but the term usually connotes the inclusion of public (shared user) networks. An intermediate form of network in terms of geography is a metropolitan area network (MAN). A wide area network is also defined as a network of networks, as it interconnects LANs over a wide geographical area. Answer option D is incorrect. A home area network (HAN) is a residential LAN that is used for communication between digital devices typically deployed in the home, usually a small number of personal computers and accessories, such as printers and mobile computing devices. Answer option A is incorrect. The Local Area Network (LAN) is a group of computers connected within a restricted geographic area, such as residence, educational institute, research lab, and various other organizations. It allows the users to share files and services, and is commonly used for intra-office communication. The LAN has connections with other LANs via leased lines, leased services, or by tunneling across the Internet using the virtual private network technologies.
