NETW 202 FINAL EXAM ANSWER,WELL EXPLAINED GRADED A.

TCO 5) _ is a network-scanning technique used to identify which host IP addresses are operational. (Points : 5) Answer: Ping sweep (TCO 5) _ create(s) noise that interferes with information being transmitted across unshielded copper cabling. (Points : 5) (TCO 5) _ is used in Ethernet where some pairs of twisted-pair wires are crossed, when comparing the RJ-45 connectors on either end of the cable. These 10BASE-T and 100BASE-T cables connect the pair at pins 1 and 2 on each end to pins 3 and 6 on the other end. (Points : 5) (TCO 5) _ is a general term referring to any energy signal on a transmission medium that is not part of the signal used to transmit data over that medium. (Points : 5) (TCO 5) _ are a collection of data that establishes a reference for network performance and behavior over a period of time. (Points : 5) (TCO 5) The __ provides a physical connection to the network (from the network end (Telco, ISP) of the user-to-network equipment), forwards traffic, and provides a clocking signal used to synchronize data transmission. (Points : 5) (TCO 5) The _ command will bring up a router interface. (Points : 5) (TCO 5) A(n) _ is an interference by magnetic signals caused by the flow of electricity. (Points : 5) (TCO 5) _ are parameters used with a command from a set of predefined values. (Points : 5) (TCO 6) _ Ethernet standard allows the transmission of data at 1,000,000,000 (one billion) bits per second. (Points : 5) (TCO 6) The _ table is used by a switch to associate MAC addresses with the outgoing port and LAN bridge to make forwarding and filtering decisions. It is also called a CAM table when referred to on Cisco LAN switches. (Points : 5) (TCO 6) _ refers to the time that occurs between when something is sent in a network and when it is received by another device. (Points : 5) (TCO 6) _ is the process of forwarding frames in a switch or a bridge from one port to another port or from one segment to another segment on a network. (Points : 5) (TCO 2) _ is a protocol used by the network-management software and networking devices to allow a network manager to monitor and troubleshoot network problems. (Points : 5) (TCO 2) A(n) _ is a request for information. The request is answered with a reply. (Points : 5) (TCO 2) _ is a 1-bit flag in the TCP header that is used to request from the higher layers an immediate delivery of the packet. (Points : 5) (TCO 2) _ are the values between 1,024 and 49,151. These numbers are equivalent to well-known ports in concept, but they are specifically used for nonprivileged applications and user processes. (Points : 5) (TCO 2) Binary digit is decimal number _. (Points : 5) (TCO 2) _ is a private-address block. (Points : 5) (TCO 3) The formula for calculating the number of hosts in a network is _. (Points : 5) (TCO 3) The 8-bit _ field describes the maximum hops the packet can take before it is considered lost or undeliverable. (Points : 5) (TCO 3) The _ is a routing table entry used to direct packets for which a next hop is not explicitly listed in the routing table. (Points : 5) (TCO 3) _ are protocols used between routers so that they can learn routes to add to their routing table. (Points : 5) (TCO 4) _ is where a station can transmit and receive communication at the same time and there are no collisions with this Ethernet transmission. (Points : 5) (TCO 4) _ is the term describing a device communicating at Layer 2 of the OSI Model. (Points : 5) (TCO 1) The _ is the network that combines enterprise networks, individual users, and ISPs into a single, global IP network. (Points : 5) (TCO 1) _ is a numbering system characterized by 1s (on) and 0s (off). (Points : 5) (TCO 1) A(n) _ is a collection of computers, printers, routers, switches, and other devices that can communicate with each other over some transmission medium. (Points : 5) (TCO 1) A(an) _ is a corporate system, such as a website, that is explicitly used by internal employees. (Points : 5) (TCO 7) The media standard maximum distance for 100BASE-TX cable is _. (Points : 5) (TCO 7) _ refers to the cables connecting the telecommunication room with the work area. (Points : 5) (TCO 7) _ keeps cabling neat and easy to thread. (Points : 5) What are the two common LAN sublayers of the OSI Model Data Link Layer, and what network services do they provide? Given that you have the Class C network address 192.168.89.0 and that you have borrowed one bit, what is the maximum number of hosts per subnet? Given a Class A network with the /21 prefix, determine the subnet mask in binary and in decimal. Then calculate the maximum number of hosts it can support Explain the 3 major modes of the Cisco IOS from top to bottom and the specific set of commands that are available when in that mode. Identify and describe how the TCP three-way handshake works to ensure data delivery. Explain the difference between throughput and bandwidth on a network. Describe three responsibilities of the Data Link Layer of the OSI Model Describe some of the advantages to using a switch on a network, name four. Looking at your list of advantages to using a switch on a network, why might you choose a switch over a hub on a network? Name the 6 fields of the 802.3 Ethernet frame and their function on the network. Include the maximum byte size of each field in your answer? Identify and explain five criteria network administrators often consider in the process of choosing cable.
