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






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






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






4. 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






5. HDLC stands for what?






6. No authentication






7. What are the PPP Data Link protocols?






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






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






10. One bit at a time over a single channel






11. Method of establishing and configuring different Network layer protocols






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






13. Proprietary






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






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






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






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






18. Method for encapsulating datagrams over serial links






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






20. 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






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






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






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






24. 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






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






26. Which is true regarding HDLC?






27. WAN stands for?






28. Bit-oriented Data Link layer protocol






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






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






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






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






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






34. What does PPP mean?






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






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






37. Uses MD5 challange/response






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






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






40. Nonproprietary






41. What are the two PPP authentication methods?






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






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






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






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






46. 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






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






48. 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






49. Physical layer international standard for serial communication






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