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






2. Which is true regarding HDLC?






3. 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)






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






5. 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






6. Write the commands to configure s0 to PPP encapsulation






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






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






9. One bit at a time over a single channel






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






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






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






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






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






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






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






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






18. 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






19. Which PPP protocol provides link establishment?






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






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






22. 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






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






24. 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






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






26. 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






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






28. No authentication






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






30. WAN stands for?






31. Method of establishing and configuring different Network layer protocols






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






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






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






35. 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






36. Uses MD5 challange/response






37. What are common Data Link WAN encapsulations?






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






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






40. 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






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






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






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






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






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






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






47. What are the PPP Data Link protocols?






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






49. Method for encapsulating datagrams over serial links






50. 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
