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. Bit-oriented Data Link layer protocol






2. What are common Data Link WAN encapsulations?






3. One bit at a time over a single channel






4. Less secure; Passwords are sent in clear text






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






6. Physical layer international standard for serial communication






7. 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






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






9. What does PPP mean?






10. Which Data Link encapsulation can be used if you have one free serial interface and many remote offices to connect?






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






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






13. Method of establishing and configuring different Network layer protocols






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






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






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






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






18. 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






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






20. HDLC stands for what?






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






22. Which is true regarding HDLC?






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






24. Write the commands to configure s0 to PPP encapsulation






25. Which PPP protocol provides link establishment?






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






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






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






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






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






31. 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)






32. Uses MD5 challange/response






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






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






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






36. This point connects the customers to the provider's switching network






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






38. Can encapsulate several layer 3 routed protocols and provide authentication - dynamic addressing - and callback






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






40. 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






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






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






43. No authentication






44. Proprietary






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






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






47. What are the two PPP authentication methods?






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






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






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