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. HDLC stands for what?






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






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






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






5. Less secure; Passwords are sent in clear text






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






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






8. Proprietary






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






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






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






12. Method of establishing and configuring different Network layer protocols






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






14. Write the commands to configure s0 to PPP encapsulation






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






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






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






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






19. 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






20. No authentication






21. What does PPP mean?






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






23. Which PPP protocol provides link establishment?






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






25. Physical layer international standard for serial communication






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






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






28. What are common Data Link WAN encapsulations?






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






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






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






32. 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






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






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






35. Method for encapsulating datagrams over serial links






36. Uses MD5 challange/response






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






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






39. 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)






40. Which is true regarding HDLC?






41. One bit at a time over a single channel






42. What are the two PPP authentication methods?






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






44. 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






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






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






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






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






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






50. Bit-oriented Data Link layer protocol
