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. 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)






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






3. HDLC stands for what?






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






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






6. Method of establishing and configuring different Network layer protocols






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






8. Proprietary






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






10. 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






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






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






13. Which PPP protocol provides link establishment?






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






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






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






17. Which is true regarding HDLC?






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






19. Less secure; Passwords are sent in clear text






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






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






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






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






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






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






26. Write the commands to configure s0 to PPP encapsulation






27. 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






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






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






30. 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






31. WAN stands for?






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






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






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






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






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






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






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






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






40. What are the PPP Data Link protocols?






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






42. 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






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






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






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






46. Nonproprietary






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. 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






49. What are the two PPP authentication methods?






50. What are common Data Link WAN encapsulations?
