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. An internationally recognized definition of technical specifications that ensure worldwide consistency.






2. A broadcast that is sent to a specific network or series of networks.






3. A logical network composed of all the computers and networking devices that can be reached by sending a frame to the data link layer broadcast address.






4. 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






5. Additional data that is provided with a command to provide information used by the execution of the command. IOS command arguments are entered at the CLI after the command






6. 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






7. A drag-and-drop network simulator developed by Cisco to design - configure and troubleshoot network equipment within a controlled - simulated program environment.






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






9. A network device that accesses a service on another computer remotely by accessing the network.






10. The physical interface transceivers. It deals with Layer 1 (the physical layer - hence the PHY) of ethernet.






11. A logical connection between devices in which the frames are passed between the devices. Virtual circuits are independent of the physical structure and may be established through multiple physical devices.






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






13. A 1-bit flag in the TCP header that is used to request that a connection be re-established.






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






15. Refers to whether the performance of a device - attached to a particular type of LAN - can be accurately predicted. Token Ring LANS are deterministic - but ethernet LANS are non deterministic.






16. In networking - a symbol used when drawing network diagrams that represent a part of the network whose details can be ignored for the purposes of the diagram.






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






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






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






20. Resources used to manage or operate the network. Overhead consumes bandwidth and reduces the amount of application data that can be transported across the network.






21. 1.collection of computers - printers - routers - switches - and other devices that can communication with each other over some transmission medium. 2. command that assgins a NIC based address to which the router is directly connected.






22. 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






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






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






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






26. A MAC address that can be configured on a device. The LAA can be used in place of the BIA . This means that you can replace a NIC or use a substitute device without changing the address used by the network to access the station.






27. The IEEE 802.2 standard that defines the upper sublayer of the Ethernet Layer 2 specifications.






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






29. 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.






30. 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.






31. 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.






32. A unicast IP address that is considered to have three parts: a network part - a subnet part - and a host part. The term classful refers to the fact that classful network rules are first applied to the address - and then the rest of the address can be






33. Unique addresses that are public domain addresses.






34. The devices and connections of a communications network that comprise the network end of the user to network interface. The DCE provides a physical connection to the network - forwards traffic - and provides a clocking signal used to synchronize data






35. A part of a computer network that every device communicates with using the same physical medium. Network segments are extended by hubs or repeaters.






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






37. Data that directs a process. a flag in a data-link frame is an example of control data.






38. A form of transmission where one device transmits to all devices within the network or on another network






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






40. 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.






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






42. The minimum time a NIC or interface can take to send an entire frame. Slot time - then - implies a minimum frame size.






43. The time that passes while some event occurs. In networking - latency typically refers to the time that occurs between when something is sent in a network until it is received by another device.






44. A time period between ethernet frames that allows fairness with the CSMA/CD algorithm. Without a space between frames in other words - without some time with no frames being sent a NIC might always listen for silence - never hear silence and therefor






45. A group of IP addresses that have the same value in the first part of the IP addresses - for the purpose of allowing routing to identify the group by the inital part of the addresses. IP addresses in the same subnet typically sit on the same network






46. A logical storage in the host's RAM to store ARP entries






47. Physical medium that uses glass or plastic threads to transmit data. A fiber-optic cable consists of a bundle of these threads - each of which is capable of transmitting data into light waves.






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






49. 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.






50. 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
