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






2. Method of establishing and configuring different Network layer protocols






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






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






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






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






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






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






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






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






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






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






13. Nonproprietary






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






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






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






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






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






19. Which encapsulations can be configured on a serial interface? (Choose three.)






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






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






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






23. 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






24. No authentication






25. What are the two PPP authentication methods?






26. Uses MD5 challange/response






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






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






30. HDLC stands for what?






31. 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






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






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






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






35. Proprietary






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






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






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






39. WAN stands for?






40. What are the PPP Data Link protocols?






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






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






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






44. One bit at a time over a single channel






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






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






47. 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






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






49. Which PPP protocol provides link establishment?






50. Bit-oriented Data Link layer protocol
