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






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






3. Write the commands to configure s0 to PPP encapsulation






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






5. Proprietary






6. 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






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






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






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






10. Which PPP protocol provides link establishment?






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






12. Data Link and Physical layer specification that provides high performance; successor to X.25






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






14. Less secure; Passwords are sent in clear text






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






16. Nonproprietary






17. Bit-oriented Data Link layer protocol






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






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






20. 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






21. 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






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






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






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






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






28. Method for encapsulating datagrams over serial links






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






30. What are the two PPP authentication methods?






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






32. No authentication






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






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






35. 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






36. 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






37. What are common Data Link WAN encapsulations?






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






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






40. 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






41. What does PPP mean?






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






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






44. 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






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






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






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






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






49. What are the PPP Data Link protocols?






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