Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Part of a company's intranet that is extended to users outside the company






2. A logical storage in a host's RAM to store arp entries.






3. IPv4 address of a network host. When talking about host addresses - they are the network layer addresses.






4. Random-access memory that does not lose its contents when the computer is shut down






5. A 1-bit flag in the TCP header that is used to request to the higher layers for immediate delivery of the packet.






6. An IP address that has been registered with IANA or one of its member agencies - which guarantees that the address is globally unique. Globally unique public IP addresses can be used for packets sent through the Internet.






7. A process used by a switch or bridge to forward broadcasts and unknown destination unicasts. The bridge/switch forwards these frames out all ports except the port on which the frame was received.






8. A computer program that runs in the background and is usually initiated as a process. Daemons often support server processes.






9. A part of the ethernet frame that fills in the data field to ensure that the data field meets the minimum size requirement of 46 bytes.






10. A common name for ethernet technology that operates at 100 mbps.






11. Line code in which each bit of data is signified by at least one voltage level transition.






12. A dotted decimal number that helps identify the structure of IP addresses. The mask represents the network and subnet parts of related IP addresses with binary 1s and the host part of related IP addresses with binary 0s






13. A grouping of code that meets a certain - already specified - condition for entering in that certain group.






14. A network scanning technique used to identify which host IP addresses are operational.






15. A network with a geographic size between a LAN and a WAN. Typically used by service providers to create a highspeed network in a major metropolitan area where many customers might want high speed services between large sites around a city.






16. The process by which a router receives an incoming frame - discards the ata link header and trailer - makes a forwarding decision based on the destination IP address - adds a new data-link header and trailer based on the outgoing interface and forwar






17. This field of a frame signals the beginning or end of a frame.






18. A form of signal modulation where the message information is encoded in the amplitude of series of signal pulses. It transmits data by varying the aplitunes of the individual pulses. This is now obsolete and has been replaced by pulse code modulation






19. Computer hardware - typically used for LANS - that allows the computer to connect to some network cable. The NIC can then send and receive data over the cable at the direction of the computer.






20. The origin of the PDU. This can be a process a host or a node - depending on the layer to which you are reffering.






21. Devices at the user end of a user-network interface that serves as a data source - destination or both. DTE connects to a data network through a DCE device and typically uses clocking signals generated by the DCE. DTE includes such devices as compute






22. A group that receives a multicast transmission. The members of a multicast group have the same mulitcast IP addressing to receive the same transmission.






23. A 32-bit number - written in dotted decimal notation - used by the IP to uniquely identify an interface connected to an IP network. It is also used as a destination address in an IP header to allow routing - and as a source address to allow a compute






24. A method of internal processing by LAN switches. The switch must receive the entire frame before it sends the first bit of the frame. Store and forward switch is the method used by cisco switches.






25. TCP or UDP ports that range from 49152 to 65535 and are not used by any defined server applications.






26. As part of the TCP/IP internet layer - ICMP defines protocol messages used to inform network engineeres of how well an internetwork is working. For example - the ping command sends ICMP messages to determine whether a host can send packets ot another






27. The networking layers whose processes are not affected by the media being used. In ethernet - these are all the layers from the LLC sublayer of data link upward.






28. In IP subnetting - this refers to the portion of a set of IP addresses whose value must be identical for the addresses to be in the same subnet.






29. A device such as a desktop or mobile device that is used by an end user.






30. A number used in the 802.11 header to specify the session between a wireless client and the access point.






31. An application protocol typically not used by end users. Instead - it is used by the network management software and networking devices to allow a network engineer to monitor and troubleshoot network problems.






32. A protocol that allows a computer to retrieve email from a server.






33. A name - as defined by DNS that uniquely identifies a computer in the internet. DNS servers can then respond to the DNS requests by supplying the IP address that is used by the computer that has a particular domain name. This term also refers to the






34. A protocol used between routers so that they can learn routes to add to their routing tables.






35. In ethernet - a device that receives an electrical signal in one port - interprets the bits and regenerates a clean signal that it sends out all other ports of the hub. Typically it also supplies several ports - which are oftentimes RJ-45 jacks.






36. Data link layer term describing a device connected to a network.






37. A request for information. Queries are answered with replies.






38. In networking - this term is used in several ways. With ethernet hub and switch hardware - port is simply another name for interface - which is a physical connector in the swithc into whic a cable can be connected. With TCP and UDP - a port is a soft






39. Path through an internetwork through which packets are forwarded.






40. Another form of the root word converge in the phrase converged network. This kind of network aggregates various forms of traffic such as voice - video and data on the same network infrastructure. A more common usage represents the process by which ro






41. In networking - a measurement of the speed of bits that can be transmitted over a particular link. It is the amount of data that can be transmitted in a certain amount of time. For digital bandwidth it is usually expressed in bits per second.






42. A routing feature in which frames in an interface output queue are prioritized based on various characteristics such as packet size and interface type.






43. In LAN switches a reference to cases in which a frame is forwarded - or switche - when the incoming and outgoing interfaces use the same speed. It is the opposite of asymmetric switching.






44. Ethernet that transmits data at 1 -000 -000 -000 one billion bits per second.






45. The design on networks that can continue to operate without interruption in the case of hardware - software or communications failures.






46. A model that consists of various layers that enable the development and explanation of technology to be done on a modular basis. This allows interoperability among different technologies among the different layers.






47. A network that is connected to a device's interface. For example networks that interface with the router are known to be directly connected. Devices learn their initial IP routes based on being connected to these subnets.






48. A type of network cabling that includes twisted-pair wires - with shielding around each pair of wires - as well as another shield around all wires in the cable.






49. The header defined by the IP. Used to create IP packets by encapsulating data supplied by higher-layer protocol (such as TCP) behind an IP header.






50. An application level network protocl mainly applied to shared access to files - printers - serial ports - and miscellaneous communications between nodes on a network.
