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






2. Write the commands to configure s0 to PPP encapsulation






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






4. Proprietary






5. One bit at a time over a single channel






6. Nonproprietary






7. Uses MD5 challange/response






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






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






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






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






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






13. Less secure; Passwords are sent in clear text






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






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






16. 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






17. 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)






18. Which is true regarding HDLC?






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






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






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






22. 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






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






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






25. What does PPP mean?






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






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






28. 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






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






30. Physical layer international standard for serial communication






31. Bit-oriented Data Link layer protocol






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






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






34. No authentication






35. What are common Data Link WAN encapsulations?






36. 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






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






38. 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






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






40. What are the two PPP authentication methods?






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






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






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






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






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






46. What are the PPP Data Link protocols?






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






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






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






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