NEW QUESTION # 104
Which of the following cables is made of glass or plastic and transmits signals in the form of light?
- A. Twisted pair cable
- B. Fiber optic cable
- C. Plenum cable
- D. Coaxial cable
Answer: B
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 # 106
Which of the following is an intrusion detection system that monitors and analyzes the internals of a computing system rather than the network packets on its external interfaces?
- A. HIDS
- B. DMZ
- C. NIDS
- D. IPS
Answer: A
Explanation:
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 D is incorrect. 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 system does.
Answer option A is incorrect. IPS (Intrusion Prevention Systems), also known as Intrusion Detection and Prevention Systems (IDPS), are network security appliances that monitor network and/or system activities for malicious activity. The main functions of "intrusion prevention systems" are to identify malicious activity, log information about said activity, attempt to block/stop activity, and report activity. An IPS can take such actions as sending an alarm, dropping the malicious packets, resetting the connection and/or blocking the traffic from the offending IP address. An IPS can also correct CRC, unfragment packet streams, prevent TCP sequencing issues, and clean up unwanted transport and network layer options.
Answer option C is incorrect. DMZ, or demilitarized zone, is a physical or logical subnetwork that contains and exposes an organization's external services to a larger untrusted network, usually the Internet. The term is normally referred to as a DMZ by IT professionals. It is sometimes referred to as a Perimeter Network. 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 any other part of the network.

NEW QUESTION # 109
Which of the following is a standard protocol for interfacing external application software with an information
server, commonly a Web server?
- A. IP
- B. TCP
- C. DHCP
- D. CGI
Answer: D
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.

- A. Group policy
- B. Issue-Specific Security Policy
- C. User policy
- D. IT policy
Answer: B
Explanation:
The Issue-Specific Security Policy (ISSP) is used to add additional information about the overall security posture. It helps in providing detailed, targeted guidance for instructing organizations in the secure use of tech systems. This policy serves to protect employees and organizations from inefficiency or ambiguity. Answer option A is incorrect. A user policy helps in defining what users can and should do to use network and organization's computer equipment. It also defines what limitations are put on users for maintaining the network secure such as whether users can install programs on their workstations, types of programs users are using, and how users can access data. Answer option D is incorrect. IT policy includes general policies for the IT department. These policies are intended to keep the network secure and stable. It includes the following: Virus incident and security incident Backup policy Client update policies Server configuration, patch update, and modification policies (security) Firewall policiesDmz policy, email retention, and auto forwarded email policy Answer option B is incorrect. A group policy specifies how programs, network resources, and the operating system work for users and computers in an organization.
