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






3. What are the two PPP authentication methods?






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






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






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






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






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






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. Less secure; Passwords are sent in clear text






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






12. Uses MD5 challange/response






13. Physical layer international standard for serial communication






14. Method of establishing and configuring different Network layer protocols






15. What does PPP mean?






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






17. WAN stands for?






18. 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






19. 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






20. What are the PPP Data Link protocols?






21. Proprietary






22. No authentication






23. One bit at a time over a single channel






24. 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






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






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






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






28. Method for encapsulating datagrams over serial links






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






30. 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






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






32. Which PPP protocol provides link establishment?






33. What are common Data Link WAN encapsulations?






34. HDLC stands for what?






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






36. Which is true regarding HDLC?






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






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






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






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






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






42. Bit-oriented Data Link layer protocol






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






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






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






46. 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






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






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






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






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