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






3. 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






4. Bit-oriented Data Link layer protocol






5. Method of establishing and configuring different Network layer protocols






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






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






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






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






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






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






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






13. The Acme Corporation is implementing dial-up services to enable remote-office employees to connect to the local network. The company uses multiple routed protocols - needs authentication of users connecting to the network - and - since some calls wil






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






15. What are the PPP Data Link protocols?






16. Which PPP protocol provides link establishment?






17. 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






18. WAN stands for?






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






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






21. What are the two PPP authentication methods?






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






23. Which is true regarding HDLC?






24. One bit at a time over a single channel






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






26. 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)






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






28. 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






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






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






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






32. 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






33. Nonproprietary






34. Physical layer international standard for serial communication






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






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






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






38. No authentication






39. HDLC stands for what?






40. Less secure; Passwords are sent in clear text






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






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






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






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






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






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






48. What are common Data Link WAN encapsulations?






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






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