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. What does PPP mean?






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






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






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






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






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






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






8. Write the commands to configure s0 to PPP encapsulation






9. 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






10. 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






11. Method of establishing and configuring different Network layer protocols






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






13. 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






14. Physical layer international standard for serial communication






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






16. Less secure; Passwords are sent in clear text






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






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






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






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






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






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






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






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






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






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






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






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






29. 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






30. Proprietary






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






32. WAN stands for?






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






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






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






36. Which is true regarding HDLC?






37. 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






38. What are the two PPP authentication methods?






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






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






41. Which PPP protocol provides link establishment?






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






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






44. HDLC stands for what?






45. Bit-oriented Data Link layer protocol






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






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






48. 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)






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






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