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. 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






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






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






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






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






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






7. 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)






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






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






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






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






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






13. Write the commands to configure s0 to PPP encapsulation






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






15. One bit at a time over a single channel






16. What are the PPP Data Link protocols?






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






18. Which PPP protocol provides link establishment?






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






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






21. 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






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






23. 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






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






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






26. 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






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






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






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






30. HDLC stands for what?






31. 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






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






33. Less secure; Passwords are sent in clear text






34. What are the two PPP authentication methods?






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






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






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






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






39. Method of establishing and configuring different Network layer protocols






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






41. What does PPP mean?






42. Uses MD5 challange/response






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






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






45. Nonproprietary






46. Which is true regarding HDLC?






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






48. Method for encapsulating datagrams over serial links






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






50. Bit-oriented Data Link layer protocol
