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 spreading of light signal caused by light signals traveling at different speeds through a fiber.






2. In ethernet - a device that receives an electrical signal in one port - interprets the bits and regenerates a clean signal that it sends out all other ports of the hub. Typically it also supplies several ports - which are oftentimes RJ-45 jacks.






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. Application-level throughput. It is the number of useful bits per unit of time from a certain source address to a certain destination - excluding protocol overhead and excluding retransmitted data packets.






5. 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.






6. 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






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






8. 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






9. Somtimes called place-value notation - this is a numeral system in which each position is related to the next by a constant multiplier - a common ration - called the base or radix of that numeral system.






10. 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






11. 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.






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






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






14. 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






15. Communication that only allows one station to receive while the other station is transmitting






16. 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.






17. 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.






18. 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.






19. 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






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






21. 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






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






23. A 1-bit flag in the TCP header used to indicate that the receiving host should notify the destination process to do urgent processing.






24. A signal on a medium used to support the transmission of data. Data is carried over the medium by modulation.






25. An encoding scheme 4B/5B uses 5-bit symbols and codes to represent 4 bits of data. 4B/5B is used in 100Base-tx ethernet.






26. 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






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






28. 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






29. 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.






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






31. A number used in the 802.11 header to specify the session between a wireless client and the access point.






32. A 1-bit flag in the tcp header that indicates the acknowledgment field is valid.






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






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






35. The client part of the DNS client server mechanism. A DNS resolver creates queries sent a across a network to a same server - interprets responses - and returns information to the requesting programs.






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






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






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






39. 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.






40. Communication that uses a common clocking signal. In most synchronous communicatino - one of the communicating devices generates a clock signal into the circuit. Additional timing information is not required in the header.






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






42. An IPv4 address in the range of 169.254.1.0 to 169.254.254.255. Communication using these addresses is used with a ttl of 1 and limited to the local network






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






44. A network with a geographic size between a LAN and a WAN. Typically used by service providers to create a highspeed network in a major metropolitan area where many customers might want high speed services between large sites around a city.






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






46. The dividing of IP datagrams to meet the MTU requirement of a layer 2 protocol.






47. 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






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






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






50. 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.
