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






2. One bit at a time over a single channel






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






4. Method of establishing and configuring different Network layer protocols






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






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






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






8. Method for encapsulating datagrams over serial links






9. Uses MD5 challange/response






10. WAN stands for?






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






12. What does PPP mean?






13. 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






14. Nonproprietary






15. 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)






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






17. What are the two PPP authentication methods?






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






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






20. Which PPP protocol provides link establishment?






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






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






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






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






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






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






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






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






29. What are the PPP Data Link protocols?






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






31. 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






32. Uses cells instead of packets that are a fixed 53 bytes long; can use isochronous clocking (external clocking) to help the data move faster; provides simultaneous transmission of voice - video - and data






33. 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






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






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






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






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






38. Proprietary






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






40. HDLC stands for what?






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






42. What are common Data Link WAN encapsulations?






43. Bit-oriented Data Link layer protocol






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






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






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






47. Less secure; Passwords are sent in clear text






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






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






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