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






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






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






4. What are the two PPP authentication methods?






5. 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)






6. Method for encapsulating datagrams over serial links






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






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






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






10. What does PPP mean?






11. 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






12. Data Link and Physical layer specification that provides high performance; successor to X.25






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






14. What is the reason why the serial link between the Corp router and the Remote router will not come up?






15. What are common Data Link WAN encapsulations?






16. 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






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






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






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






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






21. Uses MD5 challange/response






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






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






24. One bit at a time over a single channel






25. The Acme Corporation is implementing dial-up services to enable remote-office employees to connect to the local network. The company uses multiple routed protocols - needs authentication of users connecting to the network - and - since some calls wil






26. 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






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






30. 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






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






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






33. HDLC stands for what?






34. Physical layer international standard for serial communication






35. What are the PPP Data Link protocols?






36. Bit-oriented Data Link layer protocol






37. 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






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






39. Write the commands to configure s0 to PPP encapsulation






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






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






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






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






44. LCP packets are sent by each PPP device to configure and test the link






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






46. 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






47. WAN stands for?






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






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






50. Write the command to see the encapsulation method on serial 0 of a Cisco router
