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. Which layer in the OSI network model is responsible for providing a set of interfaces for applications to obtain access to networked services?






2. Wall-mounted panel of data receptors into which cross-connect patch cables from the punch-down block are inserted






3. A fiber-optic data transport method capable of a 100-Mbps transfer rate using a dual ring topology; largely supplanted today by faster Ethernet method.






4. FDDI






5. Change in signal strength as a result of reflection - scattering - or diffraction






6. ICS






7. Wide area network






8. Process in which an NIDPS inspects the higher-order protocols (HTTP - FTP - Telnet) are examined for unexpected packet behavior or improper use






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






10. The cabling or radio waves used to connect one network computer to another - or one network to another - and transport data between them. - Means by which a communications signal is carried from one system to another (for example - twisted-pair wire






11. Strength of digital signal






12. All wires are reversed






13. Uses light to communicate a signal; the light is dispersed on numerous paths as it travels through the core and is reflected back. Provides high bandwidth at high speeds over medium distances up to about 3000 feet






14. Consists of procedures and systems that identify system intrusions






15. The process of validating a user.






16. Network standard that can reliaby transmit data farthest






17. A boundary between two zones of trust






18. A logical grouping of information that includes the network layer header and encapsulated data - but specifically does not include any headers and trailers below the network layer.






19. Layer 1 Troubleshooting






20. Maximum arc into which you can loop a cable before you will cause data transmission errors






21. On a computer that receives data over a network - the process in which the device interprets the lower-layer headers and - when finished with each header - removes the header - revealing the next-higher-layer PDU.






22. The actual data - any communication that encodes a message






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






24. The medium that carries multiple signals simultaneously






25. A term used to refer to data within the Data-link layer of the OSI model.






26. Performs name resolution






27. The transmission capacity of a communications medium - which is typically measured in bits per second (for data transmissions) or hertz (for data - voice - and video transmissions) - and which is determined by the maximum minus the minimum transmissi






28. Tools in order to connect a new RJ45






29. The communication between two networking devices for the purposes of the functions defined at a particular layer of a networking model - with the communication happening by using a header defined by that layer of the model. The two devices set values






30. Data terminal equipment - little independent data processing capability. ex. workstation






31. BERT






32. POE standard






33. IPSec






34. Ethernet communications at speeds up to 100 Mbps as defined under the IEEE 802.3u standard.






35. Has 25 pins also commonly used with serial communication that conforms to the rs-232 standard






36. A data encryption technique employed between a server and a client - such as between a client's browser and an Internet server.






37. Used to determine where patch cable for a specific server terminates on the patch panel - and checks for the presence of noise on a wire






38. Local area network






39. An error detection method that calculates a value for the total size of the information fields contained in a frame. The value is inserted near the end of a frame by the Data Link layer on the sending node - and checked by the Data Link layer on the






40. Device that separates multiplexed signals once they are received and regenerates them in their original form






41. Faster wireless standard 20-25






42. OU






43. Network-max segment length-100 meters






44. Security measure verifies that your user name and password are contained in the NOS directory






45. Is a method for automatically assigning address and other configuration parameters to network hosts.






46. Describes the relative strength over a three dimensional area of an antenna






47. Device that boosts - or strengthens - and analog signal






48. Speed: 10 Mbps - Alternative Name: 10BASE-T - IEEE Standard: IEEE 802.3 - Cable Type: Copper - max length 100 meters






49. Transforms data into a form network or applications will understand






50. A resistor that is connected to the end of a segment on a bus network - so that data-carrying signals are absorbed at the point where the segment stops. Absorbing the signals ensures they are not reflected back onto the cable after they reach the end
