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. 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.






2. An international - nonprofit organization for the advancement of technology related to eletricity. IEEE maintains the standards defining many LAN protocols.






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






4. 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.






5. 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.






6. A computer program that runs in the background and is usually initiated as a process. Daemons often support server processes.






7. 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






8. A popular certification method for fiber systems. The OTDR injects light into the fiber and then graphically displays the results of the detected reflected light. The OTDR measures the elapsed transit time of reflected light to calculate the distance






9. The ability of a protocol. system or component to be modified to fit a new need.






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






11. An access method used with some LAN technologies by which devices access the media in a controlled manner. This access to the LAN is managed using a small frame called a toke. A device can send only when it has claimed the use of the token.






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






13. A method of expressing a network prefix. It uses a forward slash / followed by the network prefix.






14. A protocol used to dynamically assign IP configurations to hosts. The services defined by the protocol are used to request and assign an IP address - default gateway - and DNS server address to a network host.






15. A model that consists of various layers that enable the development and explanation of technology to be done on a modular basis. This allows interoperability among different technologies among the different layers.






16. 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






17. 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.






18. DNS data records. Their precise format is defined in RFC 1035. The most important fields in a resource record are Name - class - type and data.






19. 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






20. 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.






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






22. 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.






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






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






25. 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.






26. Using values between 1024 and 49 -151 these numbers are equivalent to well-known ports in concept - but they are specifically used for nonprivileged application processes.






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






28. 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.






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






30. 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






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






32. 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.






33. Routing that adjusts automatically to network topology or traffic changes.






34. A request for information. Queries are answered with replies.






35. A group that receives a multicast transmission. The members of a multicast group have the same mulitcast IP addressing to receive the same transmission.






36. 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






37. The layer 3 address to which the data is going.






38. 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






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






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






41. 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.






42. One of the three basic binary logic operations. ANDing yields the following result: 1 and 1 = 1 - 1 and 0 = 0 - 0 and 1 = 0






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






44. Ethernet that transmits data at 1 -000 -000 -000 one billion bits per second.






45. Data link layer term describing a device connected to a network.






46. 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.






47. A network device that has an IPv4 address assigned to it to communication over a network.






48. 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.






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






50. 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
