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. 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.






2. The connection of devices on a common media. Sometimes a physical network is also referred to as a network segment.






3. A corporate system such as a website that is explicitly used by internal employees. Can be assessed internally or remotely






4. In ethernet - the process performed by a bridge or switch when it decides that it should not forward a frame out another port






5. A list of router holds in memory for the purpose of deciding how to forward packets.






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






7. 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.






8. The forwarding of packets where the forwarding decision is taken dynamically - hop by hop - based on the conditions of downstream fowrading nodes.






9. The optical or electrical impulse on a physical medium for purposes of communication.






10. 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.






11. A written specification that defines what tasks a service or device should perform. Each protocol defines messages - often in the form of headers - plus the rules and processes by which these messages are used to achieve some stated purpose.






12. A network model defined by the IETF that has been implemented on most computers and network device in the world.






13. Radio frequencies that creat noise that interferes with information being transmitted across unshielded copper cabling.






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






15. The arrangement of the nodes in a network and the physical connections between them. This is the representation of how the media is used to connect the devices.






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






17. 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.






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






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






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






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






22. 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






23. 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.






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






25. 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.






26. 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






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






29. 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.






30. 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.






31. 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






32. 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.






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






34. In ethernet a layer 2 device that receives an electrical signal in one port - interprets the bits - and makes a filtering or forwarding decision about the frame. If it forward - it sends a regenerated signal. Switches typically have many physical por






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






36. The process of obscuring information to make it unreadable without special knowledge - somtimes referred to as scrambling. The process takes the data to be encrypted and applies a mathematical formula to it along with a secret number. The resulting v






37. A company that helps create the Internet by providing connectivity to enterprises and individuals - as well as interconnecting to other ISPs to create connectivity to all other ISPs.






38. In networking - 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.






39. Communication where the sender and receiver must prearrange for communications to occur; otherwise - the communication fails.






40. 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






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






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






43. A data link layer address - for example a MAC address






44. 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...






45. A general type of cable - with the cable holding twisted pairs of copper wires and the cable itself having little shielding.






46. Represents the 0 in the binary number. In an IP subnet mask - the lower-order bits represent the host portion. Sometimes called the host portion of bits.






47. 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






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






49. 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.






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