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. 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






2. What are common Data Link WAN encapsulations?






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






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






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






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






7. What does PPP mean?






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






9. Which is true regarding HDLC?






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






11. Write the commands to configure s0 to PPP encapsulation






12. 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






13. Uses MD5 challange/response






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






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






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






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






18. Nonproprietary






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






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






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






22. One bit at a time over a single channel






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






24. Bit-oriented Data Link layer protocol






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






26. Physical layer international standard for serial communication






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






28. HDLC stands for what?






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






30. 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






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






32. Less secure; Passwords are sent in clear text






33. Method for encapsulating datagrams over serial links






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






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






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






37. No authentication






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






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






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






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






42. WAN stands for?






43. Proprietary






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






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






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






47. What are the two PPP authentication methods?






48. 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)






49. 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






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