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 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






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






3. The standards body responsible for the development and approval of TCP/IP standards






4. The reference to text based logical interfaces on an ios device. These are accesses using telnet or ssh to perform administrative tasks. VTY lines are also called virtual type terminal.






5. A 1-bit flag in the TCP header that is used to request to the higher layers for immediate delivery of the packet.






6. The learning of source addresses on incoming frames and adding them to the bridging table. After the table has been completed and when a frame is received on one of the bridge's interfaces - the bridge looks up the frame's destination address in its






7. 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






8. A network device - typically connected to a range of LAN and WAN interfaces - that forwards packets based on their destination IP addresses.






9. 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.






10. 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.






11. 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.






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






13. 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






14. A common name for ethernet technology that operates at 100 mbps.






15. 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.






16. The network that combines enterprise networks - individual users - and ISPs into a single global IP network.






17. A generic term from OSI that refers to the data - headers - and trailers about which a particular network layer is concerned.






18. The forwarding of packets where the forwarding decision is taken dynamically - hop by hop - based on the conditions of downstream fowrading nodes.






19. A device that connects multiple network segments at the data link layer of the OSI model. Bridges were the predecessor to LAN switches.






20. In networking - a measurement of the speed of bits that can be transmitted over a particular link. It is the amount of data that can be transmitted in a certain amount of time. For digital bandwidth it is usually expressed in bits per second.






21. 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.






22. 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.






23. Unique addresses that are public domain addresses.






24. A system of network design characterized by one or more major components that are required to maintain operation.






25. A data link layer address - for example a MAC address






26. A 1-bit field in the TCP header that is used by a device that wants to terminate its session with the other device. This is done by inserting the FIN flag in the flag field found in the TCP segment






27. 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






28. When used generically - this term refers to end-user data along with networking headers and trailers that are transmitted through a network. When used specifically - it is end-user data - along with the network or Internet layer headers and any highe






29. 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.






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






31. 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






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






33. 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.






34. 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.






35. 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






36. 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






37. 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.






38. An addressing scheme in which a network is partitioned into sections - with the section identifier forming one part of each destination's address and the destination identifier forming another






39. This field of a frame signals the beginning or end of a frame.






40. 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






41. Part of a company's intranet that is extended to users outside the company






42. Communication that only allows one station to receive while the other station is transmitting






43. The minimum time a NIC or interface can take to send an entire frame. Slot time - then - implies a minimum frame size.






44. Program used to download and send email. Email clients use POP3 to receive emails and use SMTP to send emails. Also called an email client






45. A logical connection between devices in which the frames are passed between the devices. Virtual circuits are independent of the physical structure and may be established through multiple physical devices.






46. From the priviledged mode - you can enter the device's global caonfiguration mode. From global configuration mode - you can configure global parameters or enter other configuration submodes such as interface - router and line configuration submodes.






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