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 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.






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






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






4. 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.






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






6. The lower of the two sublayers of the IEEE standard for ethernet. It is also the name of that sublayer






7. Used by tcp or udp - with values between 0 and 1023 - these ports are allocated by high-privilege processes. They are used so that all clients know the correct port number to connect to.






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






9. Network layer protocol in the TCP/IP stack offering a connectionless internetwork service. IP provides features for addressing - type-of-service specification - fragmentation and reassembly - and security.






10. The IP address of the originating host that is placed into the IP packet header.






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






12. 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






13. 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






14. 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.






15. In networking - this term is used in several ways. With ethernet hub and switch hardware - port is simply another name for interface - which is a physical connector in the swithc into whic a cable can be connected. With TCP and UDP - a port is a soft






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






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






18. 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.






19. Path through an internetwork through which packets are forwarded.






20. 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.






21. A list of router holds in memory for the purpose of deciding how to forward packets.






22. The number of various unique digits - including 0 that a positional number system uses to represent numbers. For example - in the binary system (base 2) the radix is 2. In the decimal system the radix is 10.






23. 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






24. 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.






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






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. 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.






28. 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.






29. A unicast IP address that is considered to have three parts: a network part - a subnet part - and a host part. The term classful refers to the fact that classful network rules are first applied to the address - and then the rest of the address can be






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






31. 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






32. A network architecture designed to eliminate network downtime cause by a single point of failure.






33. 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






34. Random-access memory that does not lose its contents when the computer is shut down






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






36. A related set of communications transactions between two or more network devices.






37. The process of forwarding frames in a switch or a bridge from one port to another port or from segment to segment






38. 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






39. 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.






40. A network scanning technique used to identify which host IP addresses are operational.






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






42. 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.






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






44. 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.






45. A communication path over a medium used to transport information from a sender to a receiver. Multiple channels can be multiplexed over a single cable






46. A form of signal modulation where the message information is encoded in the amplitude of series of signal pulses. It transmits data by varying the aplitunes of the individual pulses. This is now obsolete and has been replaced by pulse code modulation






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






48. A broadcast that is sent to a specific network or series of networks.






49. A number used in the 802.11 header to specify the session between a wireless client and the access point.






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