Subjects : cisco, it-skills, ccna
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. 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.






2. Communication that allows receipt and transmission simultaneously. A station can transmit and receive at the same time. There are no collisions with full-duplex ethernet transmision.






3. The loss of communication signal on the media. This loss is due to degradation of the energy wave over time.






4. The structure and order of words in a computer language






5. 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.






6. Network protocols or technologies that do not use the acknowledgment system to guarantee reliable delivery of information






7. Used in the CLI following the command. Keywords are parameters that are used with the command from a set of predefined values.






8. Unique addresses that are public domain addresses.






9. Routing table entry that is used to direct frames for which a next hop is not explicitly listed in the routing table. This route is used to forward a packet when no other known route exists for a give packet's destination address.






10. Part of a company's intranet that is extended to users outside the company






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






12. Define in RFC 1918 - an IP address that does not have to be globally unique because the address exists inside packets only when the packets are inside a single private IP internetwork. Private IP addresses are popularly used in most company today - w






13. A 1-bit flag in the TCP header used to indicate that the receiving host should notify the destination process to do urgent processing.






14. A removable component that has memory space for storage. Used on the router or switch for storing the compressed operating system image.






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






16. 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.






17. A process where multiple digital data streams are combined into one signal.






18. The process by which a device adds networking heads and trailers to data from an application for the eventual transmission of the data onto a transmission medium.






19. International standardization program created by ISO and ITU-T to develop standards for data networking that facilitate multivendor equipment interoperability






20. 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






21. 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






22. 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.






23. The spreading of light signal caused by light signals traveling at different speeds through a fiber.






24. Organizations that are responsible for the allocation and registration of Internet number resources within a particular region of the world. These registries include the American Registry for Internet Number for North America; RIPE network coordinati






25. A network created for devices located in a limited geographic area - through which the company owning the LAN has the right to run cables.






26. A term that describes IPv4 packets sent to all hosts in a particular network. In a directed broadcast - a single copy of the packet is routed to the specified network - where it is broadcast to all hosts on that network






27. An international - nonprofit organization for the advancement of technology related to eletricity. IEEE maintains the standards defining many LAN protocols.






28. A host or node that participates in some form of a group. For example - p2p technology defines a group of peers that participate jointly in the same activity - each one having a server and client component.






29. An ethernet frame that is less than 64 bytes in size. Runts are caused by collisions and are also know as collision fragments






30. The network that combines enterprise networks - individual users - and ISPs into a single global IP network.






31. A system of network design characterized by one or more major components that are required to maintain operation.






32. A common term for 10base5 ethernet - referring to the fact that 10base5 cabling is thicker than the coaxial cabling used for 10base2.






33. A generic term from OSI that refers to the data - headers - and trailers about which a particular network layer is concerned.






34. 1. a collision domain that is a section of a LAN that is bound by bridges - routers or switches. 2. In a LAN using a bus topology - a segment is a continuous electrical circuit that is often connected to other such segments with repeaters. 3. When us






35. The portion of a binary number that carries the most weight - the one written farthest to the left. High-order bits are the 1s in the network mask.






36. Translation RFC 1918 addresses to public domain addresses. Because RFC 1918 addresses are not routerd on the Internet - hosts accessing the Internet must use public domain addresses.






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






38. A combination of many IP subnets and networks - as created by building a network using routers. The term internwork is used to avoid confusion with the term network - because an internetwork can include several IP networks.






39. Used by tcp or udp - with values between 0 and 1023 - these ports are allocated by high-privilege processes. They are used so that all clients know the correct port number to connect to.






40. 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.






41. A network topology characterized by a central location connected to multiple hubs. In an extended star - these interconnected hubs may be connected to more hubs. It is essentially a hierarchical topology but typically is drawn with the central site i






42. Defines the commands - headers and processes by which web server and web browsers transfer files.






43. The largest IP packet size allowed to be sent out a particular interface. Ethernet interfaces default to an MTU of 1500 because the data field of an Ethernet frame should be limited to 1500 bytes - and the IP packet sits inside the ethernet frame's d






44. The range of ip addresses that can be assigned by the DHCP server.






45. A 1-bt flag in the TCP header used to indicate the initial value of the sequence number. The SYN flag is only set in the first two segments of the three-way TCP connection establishment sequence.






46. The reference to text based logical interfaces on an ios device. These are accesses using telnet or ssh to perform administrative tasks. VTY lines are also called virtual type terminal.






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






48. The layer 2 pdu that has been encoded by a data link layer protocol for digital transmission. Some different kinds of frames are ethernet frames and PPP frames.






49. Routing that adjusts automatically to network topology or traffic changes.






50. To change the energy levels transmitted over some networking medium to transmit bits over that medium.
