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






2. What are the PPP Data Link protocols?






3. WAN stands for?






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






5. What are the two PPP authentication methods?






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






7. Bit-oriented Data Link layer protocol






8. One bit at a time over a single channel






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






10. What are common Data Link WAN encapsulations?






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






12. Less secure; Passwords are sent in clear text






13. Physical layer international standard for serial communication






14. Uses MD5 challange/response






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






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






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






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






19. Proprietary






20. 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






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






22. 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






23. What does PPP mean?






24. Nonproprietary






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






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






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






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






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






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






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






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






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






35. Method of establishing and configuring different Network layer protocols






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






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






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






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






40. HDLC stands for what?






41. 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






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






43. Which is true regarding HDLC?






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






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






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






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






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






49. 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






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