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






2. What are the two PPP authentication methods?






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






4. One bit at a time over a single channel






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






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






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






8. HDLC stands for what?






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






10. 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






11. What are common Data Link WAN encapsulations?






12. What does PPP mean?






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






14. What are the PPP Data Link protocols?






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






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






17. 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






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






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






20. Write the commands to configure s0 to PPP encapsulation






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






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






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






24. Uses MD5 challange/response






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






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






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






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






29. 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)






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






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






32. Bit-oriented Data Link layer protocol






33. Proprietary






34. 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






35. 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






36. 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






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






38. Nonproprietary






39. WAN stands for?






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






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






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






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






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






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






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






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






48. Method for encapsulating datagrams over serial links






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






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