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. The first half of a MAC address. Manufactures must ensure that the value of the OUI has been registered with the IEEE. This value identifies the manufacturer of any Ethernet NIC or interface.






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






3. 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






4. A dotted decimal number that helps identify the structure of IP addresses. The mask represents the network and subnet parts of related IP addresses with binary 1s and the host part of related IP addresses with binary 0s






5. 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.






6. 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.






7. The cabling and connectors used to interconnect the network devices.






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






9. 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






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






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






12. 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.






13. A 1-bt flag in the TCP header used to indicate the initial value of the sequence number. The SYN flag is only set in the first two segments of the three-way TCP connection establishment sequence.






14. A process where multiple digital data streams are combined into one signal.






15. 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.






16. 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.






17. A numbering system characterized by 1 and 0






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






19. 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






20. 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.






21. 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






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






23. On a switch - a table that lists all known MAC addresses - and the bridges/switch port out which the bridge/switch should forward frames sent to each MAC address.






24. A process used to verify the identity of a person or process






25. The arrangement of the nodes in a network and the physical connections between them. This is the representation of how the media is used to connect the devices.






26. 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






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






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






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






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






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






32. 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






33. Unique addresses that are public domain addresses.






34. 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






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






36. 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






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






38. 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






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






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






41. 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.






42. The time required to send a single bit over some transmission medium. The time can be calculated at 1/speed - where speed is the number of bits per second sent over the medium






43. 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.






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






45. A form of transmission where one device transmits to all devices within the network or on another network






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






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






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






49. The IPv4 address block 192.0.2.0 to 192.0.2.255 that is set aside for teaching and learning purposes. These addresses can be used in documentation and network examples.






50. A protocol that allows a computer to retrieve email from a server.
