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. 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.






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






3. As filed in the TCP header that is set in a sent segment - signifies the maximum amount of unacknowledged data the host is willing to receive before the other sending host must wait for an acknowledgment.






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






5. An IPV4 addressing scheme that uses a subnet mask that does not follow classful addressing limitations. It provides increased flexibility when dividing ranges of IP addresses into separate networks. Classless addressing is considered the best in curr






6. 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






7. 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.






8. 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.






9. 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






10. 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






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






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






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






14. The IPv4 address block 192.0.2.0 to 192.0.2.255 that is set aside for teaching and learning purposes. These addresses can be used in documentation and network examples.






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






16. The standards body responsible for the development and approval of TCP/IP standards






17. 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.






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






19. This field of a frame signals the beginning or end of a frame.






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






21. 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






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






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






24. The management of data flow between devices in a network. It is used to avoid too much data arriving before a device can handle it - causing data overflow.






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






26. A notification sent from one network device to another to confirm that some event has occured.






27. An organization that assigns the numbers important to the proper operation of the TCP/IP protocol and the Internet - including assigning globally unique IP addresses.






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






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






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






31. 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.






32. 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






33. A group of devices associated by the arrangement of a hierarchial addressing scheme. Devices in the same logical network that share a common network portion of their Layer 3 addresses.






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






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






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






37. 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






38. 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.






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






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






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






42. The table used by a switch or bridge that associates MAC addresses with the outgoing port. The switch or bridge uses this table for its forwarding/filtering decisions.






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






44. 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.






45. 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.






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






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






48. A process used to verify the identity of a person or process






49. The number of various unique digits - including 0 that a positional number system uses to represent numbers. For example - in the binary system (base 2) the radix is 2. In the decimal system the radix is 10.






50. An entry in an IP routing table that was created because a network engineer entered the routing information into the router's configuration.
