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






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






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






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






5. What does PPP mean?






6. Physical layer international standard for serial communication






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






8. Write the commands to configure s0 to PPP encapsulation






9. 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






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






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






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






13. Proprietary






14. 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)






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






16. Bit-oriented Data Link layer protocol






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






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






19. What are common Data Link WAN encapsulations?






20. 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






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






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






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






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






25. Less secure; Passwords are sent in clear text






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






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






28. No authentication






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






30. 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






31. Which PPP protocol provides link establishment?






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






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






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






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






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






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






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






39. Method of establishing and configuring different Network layer protocols






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






41. 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






42. Which is true regarding HDLC?






43. 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






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






45. 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






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






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






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






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






50. What are the two PPP authentication methods?
