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






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






3. 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






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

10. What are the two PPP authentication methods?






11. Uses MD5 challange/response






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






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






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






15. WAN stands for?






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






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






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






20. One bit at a time over a single channel






21. Proprietary






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






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






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






25. What does PPP mean?






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






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






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






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






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






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






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






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






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






35. Nonproprietary






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






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






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






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






40. 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






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






42. 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)






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






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






45. No authentication






46. 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






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

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






50. Write the commands to configure s0 to PPP encapsulation
