Subject : it-skills
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. Aka main cross-connect - first point of interconnection between an organization's LAN or WAN and a service provider's facility






2. CNAME






3. POP3 - post office protocol 3






4. Signal interference caused by electrical devices that emit radio waves at the same frequency used by network signal transmissions.






5. Physical layer standard for serial communications






6. Addresses packet size






7. Assigning a unique frequency band to each communication






8. Cabling that transmit data using light waves. Higher bandwidth than other types of cabling.






9. Hackers sending emails to make it look like its legit and its actually dangerous to the workstation






10. Pipeline used to contain and protect cabling; usually made from metal






11. Cross talk that occurs between wire pairs near the source of a signal






12. Uses frame headers






13. A TCP/IP utility that allows you to look up the DNS host name of a network node by specifying its IP address - or vice versa. This is useful for verifying that a hos is configured correctly and for troubleshooting DNS resolution problems






14. End-user device - such as a workstation - terminal - or console






15. QoS






16. Groups of workstations are star connect to connectivity devices and then networked via single bus - cover long distances - easy to interconnect - more expensive - ethernet






17. Used to resolve NetBIOS names w IP address






18. Device typically used to create a VLAN






19. MAC Protocols






20. Equals a single pulse in the digital encoding system






21. Layer 1 Troubleshooting






22. Type of transmission in which signlas may travel in both directions over a medium - but only in one direction at a time






23. A transmission method that has distinct signal levels to represent binary zeroes or ones - such as +5 volts and 0 volts.






24. A standard method or format for communication between networked devices






25. Type of sensor deployed in such a way that the network traffic it is monitoring must pass through it.






26. Set of protocols that specify how wireless networks works. Most common are currently B and G. N is an emerging standard.






27. NIDPS system that examines network traffic in order to identify problems related to the flow of traffic. Most sensors are passive mode deployment only.






28. 2nd layer; bridges the networking media with the Network layer. Primary function is to divide the data it receives from the Network layer into frames to be transmitted by the Physical layer






29. Application Layer






30. Also called the star-wired ring topology - a network design in which the logic communication are in a ring - but the phyical layout of the network star.






31. Determines the network path on which to route packets - Help reduce network congestion - Establishes virtual circuits - Routes packets to other networks - resequencing packet transmissions when needed - Translates between protocols






32. The first set of six characters that make up the MAC address and that are unique to a particular manufacturer.






33. Capability for a component or system to continue functioning despite damage or malfunction






34. An IDPS that resides on particular computer or server (the host) and monitors activity only on that system. Also known as system integrity verifiers.






35. Distinct communication path between two or more nodes; may be separated logically or physically






36. Speed: 100 Mbps - Alternative name: 10BASE-TX - IEEE Standard: IEEE 802.3u - Cable Type: Copper - max length 100m






37. Binary values for each bit position






38. Which layer in the OSI network model handles data format information for networked communications?






39. Segment






40. Medium network 128-191






41. A technique in which IP address used on a private network are assigned a public IP address by a gateway when accessing a public network.






42. Offers one way for a computer to access another computer over the network or over the Internet. For example - an IBM programmer can use Telnet on a Windows XP or Red Hat Enterprise Linux computer to access a mainframe though the Internet






43. IPX & SPX






44. BDC






45. Domain Name System






46. Cross talk with 2+ wires






47. BootP






48. IPX






49. SSH






50. An app. that provides centralized authentication and authorization services for a network.
