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 are considered WAN connection types? (Choose three.)






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






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






4. Which PPP protocol provides link establishment?






5. What does PPP mean?






6. 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






7. 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






8. 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






9. 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






10. One bit at a time over a single channel






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






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






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






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






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






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






17. Nonproprietary






18. Method for encapsulating datagrams over serial links






19. Write the commands to configure s0 to PPP encapsulation






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






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






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






23. Method of establishing and configuring different Network layer protocols






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






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






26. 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)






27. 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






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






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






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






31. WAN stands for?






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






33. HDLC stands for what?






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






35. No authentication






36. The Acme Corporation is implementing dial-up services to enable remote-office employees to connect to the local network. The company uses multiple routed protocols - needs authentication of users connecting to the network - and - since some calls wil






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






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






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






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






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






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






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






44. 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






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






46. Which is true regarding HDLC?






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






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






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






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