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. Bit-oriented Data Link layer protocol






2. Physical layer international standard for serial communication






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






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






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






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






8. Method for encapsulating datagrams over serial links






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






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






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






12. One bit at a time over a single channel






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






14. 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






15. Method of establishing and configuring different Network layer protocols






16. 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






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






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






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






20. 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






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






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






23. No authentication






24. 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)






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






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






27. 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






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






29. What are common Data Link WAN encapsulations?






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






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






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






33. Which is true regarding HDLC?






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






35. Uses MD5 challange/response






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






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






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






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






40. Nonproprietary






41. Proprietary






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






43. Which PPP protocol provides link establishment?






44. What does PPP mean?






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






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






47. Write the commands to configure s0 to PPP encapsulation






48. What are the PPP Data Link protocols?






49. 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






50. WAN stands for?
