NEW QUESTION # 142
Which of the following types of transmission is the process of sending one bit at a time over a single transmission line?

Answer: C

Explanation:
In serial data transmission, one bit is sent after another (bit-serial) on a single transmission line. It is the simplest method of transmitting digital information from one point to another. This transmission is suitable for providing communication between two participants as well as for multiple participants. It is used for all long-haul communication and provides high data rates. It is also inexpensive and beneficial in transferring data over long distances. Answer option D is incorrect. In parallel data transmission, several data signals are sent simultaneously over several parallel channels. Parallel data transmission is faster than serial data transmission. It is used primarily for transferring data between devices at the same site. For instance, communication between a computer and printer is most often parallel, allowing the entire byte to be transferred in one operation. Answer option A is incorrect. The unicast transmission method is used to establish communication between a single host and a single receiver. Packets sent to a unicast address are delivered to the interface recognized by that IP address, as shown in the following figure: Answer option C is incorrect. The multicast transmission method is used to establish communication between a single host and multiple receivers. Packets are sent to all interfaces recognized by that IP address, as shown in the figure below:

NEW QUESTION # 143
Which of the following is an intrusion detection system that reads all incoming packets and tries to find suspicious patterns known as signatures or rules?

Answer: B

Explanation:
A network intrusion detection system (NIDS) is an intrusion detection system that tries to detect malicious activity such as denial of service attacks, port scans or even attempts to crack into computers by monitoring network traffic. A NIDS reads all the incoming packets and tries to find suspicious patterns known as signatures or rules. It also tries to detect incoming shell codes in the same manner that an ordinary intrusion detection systems does. Answer option A is incorrect. A host-based intrusion detection system (HIDS) produces a false alarm because of the abnormal behavior of users and the network. A host-based intrusion detection system (HIDS) is an intrusion detection system that monitors and analyses the internals of a computing system rather than the network packets on its external interfaces. A host-based Intrusion Detection System (HIDS) monitors all or parts of the dynamic behavior and the state of a computer system. HIDS looks at the state of a system, its stored information, whether in RAM, in the file system, log files or elsewhere; and checks that the contents of these appear as expected. Answer option B 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 C is incorrect. A demilitarized zone (DMZ) is a physical or logical subnetwork that contains and exposes external services of an organization to a larger network, usually the Internet. The purpose of a DMZ is to add an additional layer of security to an organization's Local Area Network (LAN); an external attacker only has access to equipment in the DMZ, rather than the whole of the network. Hosts in the DMZ have limited connectivity to specific hosts in the internal network, though communication with other hosts in the DMZ and to the external network is allowed. This allows hosts in the DMZ to provide services to both the internal and external networks, while an intervening firewall controls the traffic between the DMZ servers and the internal network clients. In a DMZ configuration, most computers on the LAN run behind a firewall connected to a public network such as the Internet.
