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






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






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






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






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






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






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






8. Less secure; Passwords are sent in clear text






9. Write the commands to configure s0 to PPP encapsulation






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






11. 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






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






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






14. Method of establishing and configuring different Network layer protocols






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






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






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






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






19. 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






20. Which PPP protocol provides link establishment?






21. One bit at a time over a single channel






22. 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






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






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






25. 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






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






27. Proprietary






28. What are common Data Link WAN encapsulations?






29. Nonproprietary






30. 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






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






32. A connection-oriented protocol at the Data Link layer for use with X.25; causes a tremendous amount of overhead because of its strict time-out and windowing techniques; can also be used as a simple data link transport






33. Which is true regarding HDLC?






34. Bit-oriented Data Link layer protocol






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






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






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






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






39. What are the PPP Data Link protocols?






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






41. What does PPP mean?






42. WAN stands for?






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






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






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






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






47. 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






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






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






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