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. What are common Data Link WAN encapsulations?






2. Uses MD5 challange/response






3. HDLC stands for what?






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






5. Write the commands to configure s0 to PPP encapsulation






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






7. 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






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






9. 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






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






11. Less secure; Passwords are sent in clear text






12. One bit at a time over a single channel






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






14. 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






15. What are the PPP Data Link protocols?






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






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






18. What are the two PPP authentication methods?






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






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






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






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






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






24. No authentication






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






26. 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






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






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






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






30. 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






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






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






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






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






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






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






37. 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)






38. What does PPP mean?






39. Physical layer international standard for serial communication






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 PPP protocol provides link establishment?






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






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






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






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






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






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






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






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