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






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






3. A map of the devices on a network representing how the devices communcate with each other.






4. 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






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






6. 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






7. Unique addresses that are public domain addresses.






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






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






10. 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.






11. In TCP - the process of taking a large chunk of data and breaking it into small enough pieces to fit within a TCP segment without breaking any rules about the maximum amount of data allowed in a segment.






12. 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.






13. A removable component that has memory space for storage. Used on the router or switch for storing the compressed operating system image.






14. 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






15. 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.






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






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






18. 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.






19. 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.






20. 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






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






22. A logical storage in the host's RAM to store ARP entries






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






24. An address used to represent a transmission from one device to all devices. In ethernet - the sepcial ethernet address FFFF.FFFF.FFFF is used as a destination MAC address to cause a frame to be sent to all devices on an ethernet LAN. In IPV4 - each s






25. Media access methodology in which a node wishing to transmit listens for a carrier wave before trying to send. If a carrier is sensed - the node waits for the transmission in progress to finish before initiating its own transmission.






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






27. The portion of a binary number that carries the most weight - the one written farthest to the left. High-order bits are the 1s in the network mask.






28. 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.






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






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






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






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






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






34. IPv4 address of a network host. When talking about host addresses - they are the network layer addresses.






35. 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.






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






37. Radio frequencies that creat noise that interferes with information being transmitted across unshielded copper cabling.






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






39. To transfer data from the computer functioning as a server to the client computer you are using.






40. An application level network protocl mainly applied to shared access to files - printers - serial ports - and miscellaneous communications between nodes on a network.






41. 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






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. 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






44. A method of computer processing in which different parts of a program run simultaneously on two or more computers that are communicating with each other over a network






45. A field in the IP header that prevents a packet form indefinitely looping around an IP internetwork. Router decrements the TTL field each time they forward a packet - and if they decrement the TTL to 0 - the router discards the packet - which prevent






46. 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






47. 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
