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. Write the commands to configure s0 to PPP encapsulation






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






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






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






5. Bit-oriented Data Link layer protocol






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






7. 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






8. Which of that following is a packet-switching 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. Used with ISDN at the Data Link layer (layer 2) as a protocol for the D (signaling) channel






11. One bit at a time over a single channel






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






13. What are common Data Link WAN encapsulations?






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






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






16. 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






17. Less secure; Passwords are sent in clear text






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






19. What does PPP mean?






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






21. HDLC stands for what?






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






23. Method of establishing and configuring different Network layer protocols






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






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






26. 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






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






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






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






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






31. WAN stands for?






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






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






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






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






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






38. Which PPP protocol provides link establishment?






39. Proprietary






40. Physical layer international standard for serial communication






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






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






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. No authentication






45. 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






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






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






48. What are the PPP Data Link protocols?






49. What are the two PPP authentication methods?






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