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. Signals composed ot pulses that can have a value of only 1 or 0






2. Process by which attacker changes the format and/or timing of their activities to avoid being detected by the IDPS






3. In TCP - a term used to describe a TCP header and its encapsulated data (also called an L4PDU). Also in TCP - the process of accepting a large chunk of data from the application layer and breaking it into smaller pieces that fit into TCP segments. In






4. Provides th transfer medium (such as cable) - Translates data into a transmission signal appropriate to the transfer medium - Sends the signal along the transfer medium - Includes the pyical layout of the network - Monitors for transmission error - D






5. Hardware device located at the ISP side of ADSL connections.






6. Which layer is responsible for putting data into frames as well as providing error checking data?






7. Core TCP/IP protocol that operates in the Network layer and provided information about how and where data should be delivered; subprotocol that enables TCP/IP to inernetwork






8. SLIP






9. Transport Layer






10. Used to log on to a UNIX host






11. IDPS that uses profiles to detect anomalous protocol behavior






12. A worldwide network network of interconnected LANs - and MANs - that uses the TCP/IP protocol to enable people to share e-mail messages and computer files and to access a vast array of infromation.






13. The combination of an IP address's network ID and subnet information. By interpreting the address's extended network prefix - a device can determine the subnet to which an address belongs.






14. Four twisted wire pairs rated for 100 Mhz - but capable of handling the disturbance on eash pair that's caused by transmitting on all four pairs at the same time.






15. Determines standards for the electronics industry and other fields - such as chemical and nuclear engineering - health and safety - and construction

17. Round time trip. time it takes for packet to get from sender to receiver and back






18. RJ 45






19. Faster wireless standard 20-25






20. A utility for viewing or modifying a host's routing table






21. A series of interconnected computers - printing devices - and other computer equipment that shares hardware and software resources. The service area usually is limited to a given office area - floor - or building.






22. 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






23. A data link protocol used for remote networking that is rarely used today.






24. Does not operate at the application layer






25. QoS






26. Domain Name System






27. Fiber Distributed Data Interface






28. A TCP/IP utility that queries the DNS database and provides information about a host given its IP address or vice versa. Dig is similar to the nslookup utility - but provides more information - even in its simplest form - than nslookup can.






29. Resistance that contributes to controlling an electrical signal; measured in ohms






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






31. The IEEE standard for Ethernet networking devices and data handling (using the CSMA/CD access method)






32. First part of the datagram - which consists of general information about the size of the packet - the protocol that was used to send it - and the IP address of both the source computer and its destination.






33. Speed: 1000 Mbps - Altenative name: 1000BASE-T - IEEE Standard: IEEE 802.3ab - Cable type: copper max length 100m






34. Address Resolution Protocol






35. Multicast group 224-239






36. Value placed upon an IDPS's ability to detect/identify certain attacks correctly






37. IDPS's ability to dynamically modify its configuration in response to environmental activity






38. Transport Layer






39. Segment






40. Modulation technique in which the amplitude of the carrier signal is modified by the application of a data signal






41. Running system for a while to track types of false positives it generates and then adjusting IDPS alarm classifications






42. A computer that has its own CPU and may be used as a stand-alone computer for word processing - spreadsheet creation - or other software applications. It also may be used to access another computer such as another workstation or server via a network.






43. Defines host IP in packet headers






44. IMAP - internet message access protocol






45. Layer 1 Troubleshooting






46. Internet control message protocol
