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






2. WAN stands for?






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






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






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






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






7. 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






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






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






10. 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






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






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






13. What are the PPP Data Link protocols?






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






15. Method for encapsulating datagrams over serial links






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






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






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






19. What are common Data Link WAN encapsulations?






20. HDLC stands for what?






21. 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






22. 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






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






24. Physical layer international standard for serial communication






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






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






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






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






29. Which is true regarding HDLC?






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






31. 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)






32. 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






33. What does PPP mean?






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






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






36. Proprietary






37. Which PPP protocol provides link establishment?






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






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






40. Uses MD5 challange/response






41. Less secure; Passwords are sent in clear text






42. What are the two PPP authentication methods?






43. Method of establishing and configuring different Network layer protocols






44. Bit-oriented Data Link layer protocol






45. Write the commands to configure s0 to PPP encapsulation






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






47. No authentication






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






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






50. 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
