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






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






3. Routing table entry that is used to direct frames for which a next hop is not explicitly listed in the routing table. This route is used to forward a packet when no other known route exists for a give packet's destination address.






4. 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






5. 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.






6. 1.collection of computers - printers - routers - switches - and other devices that can communication with each other over some transmission medium. 2. command that assgins a NIC based address to which the router is directly connected.






7. 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.






8. Line code in which each bit of data is signified by at least one voltage level transition.






9. 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.






10. 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.






11. A convention for writing IP addresses with four decimal numbers - ranging from 0 to 255 - with each octet representing 8 bits of the 32 bit IP address. The term originates from the fact that each of the four decimal numbers is separated by a period.






12. A drag-and-drop network simulator developed by Cisco to design - configure and troubleshoot network equipment within a controlled - simulated program environment.






13. 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.






14. The glass fibers inside certain cables over which light is transmitted to encode 0 and 1






15. Resources used to manage or operate the network. Overhead consumes bandwidth and reduces the amount of application data that can be transported across the network.






16. Real-time communication between two or more people through text. The text is conveyed through computers connected over a network such as the internet. files can also be transferred through the IM program to share files.






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






18. A general type of cable - with the cable holding twisted pairs of copper wires and the cable itself having little shielding.






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






20. Binary digit used in the binary numbering system. Binary digits are units of information storage and communication in computing. Each bit can be either a 0 or a 1.






21. An internet wide system by which a hierarchical set of DNS servers collectively hold all the name IP address mappings - with DNS servers referring users to the correct DNS server to successfully resolve a DNS name.






22. 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.






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






24. 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.






25. The time that passes while some event occurs. In networking - latency typically refers to the time that occurs between when something is sent in a network until it is received by another device.






26. The layer 2 pdu that has been encoded by a data link layer protocol for digital transmission. Some different kinds of frames are ethernet frames and PPP frames.






27. 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.






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






29. 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.






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






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






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






33. A group defined by a class D address (multicast - ranging from 224.0.0.0 to 239.255.255.255) - whereupon hosts can pertain to multicast groups. Hosts that have the same multicast address are part of the same host group.






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






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






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






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






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






39. 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






40. 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.






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






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






43. A type of network cabling that includes twisted-pair wires - with shielding around each pair of wires - as well as another shield around all wires in the cable.






44. Devices at the user end of a user-network interface that serves as a data source - destination or both. DTE connects to a data network through a DCE device and typically uses clocking signals generated by the DCE. DTE includes such devices as compute






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






46. A service or a program to look up information in the DNS






47. In networking - a symbol used when drawing network diagrams that represent a part of the network whose details can be ignored for the purposes of the diagram.






48. The design on networks that can continue to operate without interruption in the case of hardware - software or communications failures.






49. An internationally recognized definition of technical specifications that ensure worldwide consistency.






50. A device that connects end devices to the network or interconnects different networks. A router is an example of an intermediary device.
