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. HDLC stands for what?






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






3. Which PPP protocol provides link establishment?






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






5. What are the two PPP authentication methods?






6. WAN stands for?






7. What are common Data Link WAN encapsulations?






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






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






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






11. 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






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






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






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






15. Bit-oriented Data Link layer protocol






16. 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






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






18. Less secure; Passwords are sent in clear text






19. 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






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






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






22. 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)






23. Nonproprietary






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






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






26. 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






27. One bit at a time over a single channel






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






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






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






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






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






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






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






35. Uses MD5 challange/response






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






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






38. Proprietary






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






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






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






42. 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






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






44. Method for encapsulating datagrams over serial links






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






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






47. What does PPP mean?






48. Method of establishing and configuring different Network layer protocols






49. Write the commands to configure s0 to PPP encapsulation






50. No authentication
