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. Random-access memory that does not lose its contents when the computer is shut down






2. 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.






3. The process of forwarding frames in a switch or a bridge from one port to another port or from segment to segment






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






5. 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






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






7. 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.






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






9. The networking layers whose processes are not affected by the media being used. In ethernet - these are all the layers from the LLC sublayer of data link upward.






10. Information systems that allow the creation of a document or documents that can be edited by more than one person in real time






11. A delineation of networking protocols and standards into different categories - called layers - along with definitions of which sets of standards and protocols need to be implemented to create products that can be used to create a working network






12. 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.






13. A unit of measurement of the number of times 1000 bits can be transmitted in 1 second. 1 kbps = 1000bps






14. A physical or a logical area in a LAN where the signals sent by the interfaces ma be subject o being combined. Within a collision domain - if a device sends a frame on a network segment - every other device on that same segment will receive that fram






15. 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






16. In the telnet application - commands are always introduced by a character with the decimal code 255 - known as the Interpret as Command character.






17. 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.






18. 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






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






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






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






22. 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.






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. Computer hardware - typically used for LANS - that allows the computer to connect to some network cable. The NIC can then send and receive data over the cable at the direction of the computer.






25. A host or node that participates in some form of a group. For example - p2p technology defines a group of peers that participate jointly in the same activity - each one having a server and client component.






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






27. 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.






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






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






30. A temporary storage where data that has been retrieved or calculated and is accessed frequently can be stored. After the data is stored in the cache - the processes can access the cached copy instead of accessing the original data. A cache reduces th






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






32. 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.






33. 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.






34. A combination of many IP subnets and networks - as created by building a network using routers. The term internwork is used to avoid confusion with the term network - because an internetwork can include several IP networks.






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






36. 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






37. The structure and order of words in a computer language






38. 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.






39. An ethernet frame that is less than 64 bytes in size. Runts are caused by collisions and are also know as collision fragments






40. A communication path over a medium used to transport information from a sender to a receiver. Multiple channels can be multiplexed over a single cable






41. 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.






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






43. 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.






44. 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.

47. A related set of communications transactions between two or more network devices.






48. 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.






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






50. A technique used to attack an ethernet network by sending fake ARP messages to an ethernet LAN. These frames contain false MAC addresses that confuse network devices - such as switches. As a result - frames intended for one node can be mistakenly sen
