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. If required - either CHAP or PAP can be used to authenticate a link






2. Which is true regarding HDLC?






3. What does PPP mean?






4. Which are considered WAN connection types? (Choose three.)






5. Method of establishing and configuring different Network layer protocols






6. What are the PPP Data Link protocols?






7. WAN stands for?






8. A point-to-point connection or dedicated connection; a pre-established WAN communications path from the CPE through the DCE switch to the CPE of the remote site - allowing DTE networks to communicate at any time with no setup procedures before transm






9. Physical layer international standard for serial communication






10. Method for encapsulating datagrams over serial links






11. A connection-oriented protocol at the Data Link layer for use with X.25; causes a tremendous amount of overhead because of its strict time-out and windowing techniques; can also be used as a simple data link transport






12. Allows you to share bandwidth with other companies to save money; a network that's designed to look like a leased line yet charges you (and costs) more like circuit switching; data transfers are bursty in nature; Frame Relay and X.25






13. When a router is connected to a Frame Relay WAN link using a serial DTE interface - how is the clock rate determined?






14. Includes the area from the CSU/DSU - through the provider's wiring and switches - all the way to the CSU/DSU at the other end; provides clocking to the DTE-connected interface (the router's serial interface)






15. What is the default serial encapsulation on a Cisco router?






16. One bit at a time over a single channel






17. Uses the Network Control Protocol (NCP) to allow multiple Network layer protocols to be encapsulated and sent over a PPP data link






18. If you had one serial interface on your router and needed to connect many remote locations - which Data Link encapsulation should you use?






19. HDLC stands for what?






20. Serial interfaces by default; connect into data communication equipment (DCE)






21. Write the commands to configure a username of todd and password of cisco that is used on a Cisco router






22. Which of the following encapsulations was considered an upgrade from x.25?






23. Method of establishing - configuring - maintaining - and terminating the point-to-point connection






24. Connects the demarc to the closest switching office - called a central office






25. What are the two PPP authentication methods?






26. Which of the following are considered common Data Link WAN encapsulation types? (Choose three.)






27. Which type of port on a router is used for a T1?






28. How do you configure a serial interface to use PPP encapsulation?






29. A set of digital services that transmit voice and data over existing phone lines






30. Bit-oriented Data Link layer protocol






31. Used to create point-to-point links between different vendors' equipment; uses a Network Control Protocol field in the Data Link header to identify the Network layer protocol; allows authentication and multilink connections and can be run over asynch






32. Used with ISDN at the Data Link layer (layer 2) as a protocol for the D (signaling) channel






33. Write the commands to configure s0 to PPP encapsulation






34. Data Link layer protocol that can be used over either asynchronous serial (dial-up) or synchronous serial (ISDN) media






35. To transport layer 3 packets across a Data Link layer point-to-point link






36. What is the default serial encapsulation used on Cisco routers?






37. Protocol stack is specified at the Physical and Data Link layers only






38. If you have a T1 - what must you connect from your router to a demarc?






39. Which protocol in PPP is used to identify the routed protocols?






40. Which of that following is a packet-switching encapsulation?






41. Uses MD5 challange/response






42. What are common Data Link WAN encapsulations?






43. Designed to allow the simultaneous use of multiple Network layer protocols






44. Equipment that's owned by the subscriber and located on the subscriber's premises






45. Specifies an encapsulation method for data on synchronous serial data links using frame characters and checksums






46. The spot where the service provider's responsibility ends and the CPE begins






47. The default encapsulation used by Cisco routers over synchronous serial links






48. Nonproprietary






49. Uses the LCP (Link Control Protocol) to build and maintain data link connections






50. Which of the following protocols are used with ISDN as an out-of-band protocol?
