Wide Area Netwoking Protocols

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






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






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






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






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






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






7. Derived from Synchronous Data Link Control (SDLC); created by IBM as a Data Link connection protocol; very little overhead compared to LAPB; The HDLC header carries no identification of the type of protocol being carried inside the HDLC encapsulation






8. Write the commands to configure s0 to PPP encapsulation






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






10. To connect two DTE networks together through a DCE network






11. Bit-oriented Data Link layer protocol






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






13. Uses dial-up modems or ISDN and is used for low-bandwidth data transfers; No data can transfer before an end-to-end connection is established






14. Which encapsulations can be configured on a serial interface? (Choose three.)






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






16. Which is true regarding HDLC?






17. What does PPP mean?






18. 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






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






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






21. When PPP connections are started - the links go through three phases of session establishment. What are the three phases?






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






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






24. What are the two PPP authentication methods?






25. What is a good command to verify your serial interface on a router?






26. 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






27. Nonproprietary






28. Network Control Protocol (NCP) is used to allow multiple Network layer protocols (routed protocols) to be used on a point-to-point connection






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






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






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






32. A trunk line inside a WAN provider's network; a collection of switches and facilities owned by the ISP






33. Which PPP protocol provides link establishment?






34. A point-to-point protocol used on leased lines






35. HDLC stands for what?






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






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






38. What are common Data Link WAN encapsulations?






39. Proprietary






40. Uses MD5 challange/response






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






42. Physical layer international standard for serial communication






43. 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






44. One bit at a time over a single channel






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






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






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






48. Method of establishing and configuring different Network layer protocols






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






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