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






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






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






4. 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






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






6. What are the two PPP authentication methods?






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






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






9. Proprietary






10. What are common Data Link WAN encapsulations?






11. Write the commands to configure s0 to PPP encapsulation






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






13. Less secure; Passwords are sent in clear text






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






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






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






17. 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






18. Method for encapsulating datagrams over serial links






19. 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






20. Physical layer international standard for serial communication






21. 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






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






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






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






25. Bit-oriented Data Link layer protocol






26. WAN stands for?






27. Which is true regarding HDLC?






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






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






32. One bit at a time over a single channel






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






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






35. What does PPP mean?






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






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






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






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






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






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






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






43. 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






44. Method of establishing and configuring different Network layer protocols






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






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






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






48. Nonproprietary






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






50. Which PPP protocol provides link establishment?
