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






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






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






4. HDLC stands for what?






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






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






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






8. What are the PPP Data Link protocols?






9. 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






10. Method of establishing and configuring different Network layer protocols






11. No authentication






12. WAN stands for?






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






14. Uses MD5 challange/response






15. One bit at a time over a single channel






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






17. 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






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






19. Which PPP protocol provides link establishment?






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






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






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






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






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






25. 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






26. What are common Data Link WAN encapsulations?






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






28. Less secure; Passwords are sent in clear text






29. What does PPP mean?






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






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






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






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






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






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






36. What are the two PPP authentication methods?






37. 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






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






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






40. Physical layer international standard for serial communication






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






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






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






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






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






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






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






48. 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






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






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