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






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






3. What are common Data Link WAN encapsulations?






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






5. Proprietary






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






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






9. 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






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






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






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






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






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






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






16. Less secure; Passwords are sent in clear text






17. 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






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






19. Uses MD5 challange/response






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






21. What are the PPP Data Link protocols?






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






23. One bit at a time over a single channel






24. 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






25. Physical layer international standard for serial communication






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






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






28. 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






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






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






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






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






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






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






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






37. What does PPP mean?






38. HDLC stands for what?






39. What are the two PPP authentication methods?






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






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






42. 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






43. 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






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






45. Write the commands to configure s0 to PPP encapsulation






46. Method for encapsulating datagrams over serial links






47. Which is true regarding HDLC?






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






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






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