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 that following is a packet-switching encapsulation?






2. 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)






3. Which is true regarding HDLC?






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






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






6. 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






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






8. Which PPP protocol provides link establishment?






9. What are common Data Link WAN encapsulations?






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






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






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






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






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






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






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






17. 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






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






19. HDLC stands for what?






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






21. No authentication






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






23. Bit-oriented Data Link layer protocol






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






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






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






27. 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






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






29. Uses MD5 challange/response






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






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






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






33. Equipment that's owned by the subscriber and located on the subscriber's premises






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






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






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






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






38. Nonproprietary






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






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






41. 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






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






43. Proprietary






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






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






46. What are the PPP Data Link protocols?






47. 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






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






49. Write the commands to configure s0 to PPP encapsulation






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