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






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






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






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






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






6. 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






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






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






9. Physical layer international standard for serial communication






10. 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






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






12. 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






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






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






15. Proprietary






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






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






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






19. Which PPP protocol provides link establishment?






20. WAN stands for?






21. Method of establishing and configuring different Network layer protocols






22. Write the commands to configure s0 to PPP encapsulation






23. 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






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






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






26. One bit at a time over a single channel






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






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






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






30. What are common Data Link WAN encapsulations?






31. 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






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






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






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






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






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






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






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






39. Less secure; Passwords are sent in clear text






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






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






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






43. What are the two PPP authentication methods?






44. HDLC stands for what?






45. 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)






46. 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






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






48. What does PPP mean?






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






50. 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
