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






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






4. WAN stands for?






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






6. 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






7. 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






8. Write the commands to configure s0 to PPP encapsulation






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






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






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






12. No authentication






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






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






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






18. 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






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






20. Uses MD5 challange/response






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






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






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






24. Bit-oriented Data Link layer protocol






25. What are common Data Link WAN encapsulations?






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






27. Nonproprietary






28. 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)






29. What are the PPP Data Link protocols?






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






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






32. Which PPP protocol provides link establishment?






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






34. HDLC stands for what?






35. What does PPP mean?






36. Method for encapsulating datagrams over serial links






37. Less secure; Passwords are sent in clear text






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






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






40. What are the two PPP authentication methods?






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






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. Proprietary






44. 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






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






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






47. One bit at a time over a single channel






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






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






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