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 type of hash function that is used to produce a small - fixed size checksum of a block of data - such as a packet or a computer file. A CRC is computed and appended before transmission or storage - and verified afterward by the recipient to confirm






2. The method of for finding a host's hardware address from its IPv4 network layer address.






3. A network of computers that behave as if they are connected to the same network segment - even through they might be physically located on different segments of a LAN. VLANs are configured through software on the switch and router.






4. A service or a program to look up information in the DNS






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






6. A network that incorporates both optical fiber along with coaxial cable to create a broadband network. commonly used by cable tv companies.






7. In ethernet - the process performed by a bridge or switch when it decides that it should send a frame out another port.






8. The passage of a data packet between two network nodes.






9. A protocol for synchronizing the clocks of computer systems over packet-switch data networks. NTP uses UDP port 123 as its transport layer.






10. Line code in which 1s are represented by one significant condition and 0s are represented by another.






11. A member of a multicast group. Every multicast client in each group has the same IP address. Multicast addresses begin with 224... and end with 239...






12. 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.






13. Any communication in which the sender and receiver do not prearrange for communications to occur






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






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






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






17. The table used by a switch that associates MAC addresses with the outgoing port. A general term for the table that a LAN bridge uses for its forwarding/filtering decisions. The table holds a list of MAC addresses and the port out which the bridge sho






18. Unencrypted password used to allow access to privledge EXEC mode from IOS user EXEC mode.






19. To transfer data from the computer functioning as a server to the client computer you are using.






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






21. When used generically - this term refers to end-user data along with networking headers and trailers that are transmitted through a network. When used specifically - it is end-user data - along with the network or Internet layer headers and any highe






22. 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






23. An access method used with some LAN technologies by which devices access the media in a controlled manner. This access to the LAN is managed using a small frame called a toke. A device can send only when it has claimed the use of the token.






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






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






26. A collection of data that establishes a reference for network performance and behavior over a period of time. This reference data is used in the future to assess the health and relative growth of network utilization.






27. A high-speed line or series of connections that forms a major pathway within a network. The term is often used to describe the main network connections comprising the Internet.






28. A related set of communications transactions between two or more network devices.






29. A layer 4 protocl of TCP/IP model - TCP lets applications guarantee delivery of data across a network.






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






31. In a web browser - an application the browser uses - inside the browser window to display some types of content. For example - a browser typically uses a plug-in to display video.






32. 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.






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






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






35. Using values between 1024 and 49 -151 these numbers are equivalent to well-known ports in concept - but they are specifically used for nonprivileged application processes.






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






37. Network layer protocol in the TCP/IP stack offering a connectionless internetwork service. IP provides features for addressing - type-of-service specification - fragmentation and reassembly - and security.






38. The glass fibers inside certain cables over which light is transmitted to encode 0 and 1






39. The IPv4 multicast addresses 224.0.0.0 to 224.0.0.255. These addresses are to be used for multicast groups on a local network. Packets to these destinations are always transmitted with a TTTL value of 1






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






41. A method of computer processing in which different parts of a program run simultaneously on two or more computers that are communicating with each other over a network






42. DNS data records. Their precise format is defined in RFC 1035. The most important fields in a resource record are Name - class - type and data.






43. MDIX is an alternative operation of ethernet ports on a hub. In this mode - the mapping of the wire pairs used in the hub port is in a crossover configuration. This allows you to use a straight-through cable to interconnect the hub to another hub.






44. 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.






45. Real-time communication between two or more people through text. The text is conveyed through computers connected over a network such as the internet. files can also be transferred through the IM program to share files.






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






47. An address used to represent a transmission from one device to all devices. In ethernet - the sepcial ethernet address FFFF.FFFF.FFFF is used as a destination MAC address to cause a frame to be sent to all devices on an ethernet LAN. In IPV4 - each s






48. A device on a network that serves as an access point to other networks. A default gateway is used by a host to forward IP packets that have destination addresses outside the local subnet. A router interface typically is used as the default gateway. W






49. A control mechanism that can provide different priorities to different users or data flows - or guarantee a certain level of performance to a data flow in accordance with requests from the application program.






50. The MAC address that is permanently assigned to a LAN interface or NIC. It is called burned-in because the address is burned into a chip on the card - and the address cannot be changed. Also called universally administered address.
