  • 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 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.






2. 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.






3. A dotted decimal number defined by the IPv4 protocol to represent a network or subnet. It represents the network that hosts reside in. Also called a network number or network ID.






4. An IPv4 multicast address that is restricted to a local group or organization






5. 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






6. A process that uses the same ARP messages as a normal ARP - but by which a router replies instead of the host listed in the ARP request. When a router sees an ARP request that cannot reach the intended host - but for which the router knows a route to






7. 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






8. A source of information that is highly reliable and known for its accuracy






9. A command on many computer operating systems that discovers the IP addresses - and possibly host names - of the routers used by the network when sending a packet from one computer to another.






10. An IPv4 multicast address that is restricted to a local group or organization.






11. Binary digit used in the binary numbering system. Binary digits are units of information storage and communication in computing. Each bit can be either a 0 or a 1.






12. Program used to download and send email. Email clients use POP3 to receive emails and use SMTP to send emails. Also called an email client






13. The MAC algorithm used by ethernet devices in a shared media. The protocol requires a node wishing to transmit to listen for a carrier signal before trying to send. If a carrier is sensed - the node waits for transmission in progress to finish before






14. 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.






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






16. A numbering system characterized by 1 and 0






17. A plan - design or program of action to be followed. Sometimes an addressing plan is called an addressing SCHEME.






18. Communication that does not use a common clock between the sender and receiver. To maintain timing - additional information is sent to synchronize the receive circuit to the incoming data. For ethernet at 10MBPS - the ethernet devices do not send ele






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






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






21. 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






22. A port on cisco devices to which a terminal or computer with a terminal emulator is connected to the network device in order to communicate and configure the network device






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






24. A series of documents and memoranda encompassing new research - innovations and methodologies applicable to Internet technologies. RFCs are a reference for how technologies should work.






25. A process by which an end device - after it receives data over some transmission medium - examines the headers and trailers at each successive higher layer - eventually handing the data to the correct application. Sometimes called de-encapsulation.






26. 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.






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






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






29. 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.






30. 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.






31. Also known as boolean algebra. These consist of the AND OR and IF operations






32. In ethernet - the results of two nodes transmitting simlutaneously. The signals from each device are damaged when they combine on the media






33. 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.






34. The actual data transfer rate between two computers at some point in time. Throughput is impacted by the slowest-speed link used to send data between the two computers - as well as myriad variables that might change during the course of a day.






35. Defines which wires in a cable should connect to each pin on the connectors on both ends of a cable. For example - a UTP cable used for ethernet - used for a straight-through cable pinout - connects the wire at pin 1 on one end with the pin 1 on the






36. The learning of source addresses on incoming frames and adding them to the bridging table. After the table has been completed and when a frame is received on one of the bridge's interfaces - the bridge looks up the frame's destination address in its






37. A 32-bit field in the tcp segment header that specifies the sequence number of the next byte this host expects to receive as a part of the TCP session. It is used to recognize lost packets and flow control






38. The lower of the two sublayers of the IEEE standard for ethernet. It is also the name of that sublayer






39. An international standards body that defines many networking standards. Also - the standards body that created the OSI model.






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






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






42. 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






43. The time required for some network pdu's to be sent and received - and a response PDU to be sent and received. In other words - the time between when a device sends data and when the same device receives a response.






44. The normal operation of ethernet ports on a hub. In this mode - the mapping of the wire pairs in the hub port is in a normal configuration. Some hubs provide a media-dependent interface/media-dependent interface - crossover switch. This switch is usu






45. A rectangular cabling connector with eight pins - often used with ethernet cables.






46. 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.






47. 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.






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






49. From the priviledged mode - you can enter the device's global caonfiguration mode. From global configuration mode - you can configure global parameters or enter other configuration submodes such as interface - router and line configuration submodes.






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