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






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






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






4. 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






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






6. What are the PPP Data Link protocols?






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






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






9. 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






10. What does PPP mean?






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






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






13. Nonproprietary






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






15. What are the two PPP authentication methods?






16. 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)






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






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






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






20. 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






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






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






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






24. One bit at a time over a single channel






25. Proprietary






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






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






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






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






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






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






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






33. Bit-oriented Data Link layer protocol






34. 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






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






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






37. Uses MD5 challange/response






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






39. 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






40. Write the commands to configure s0 to PPP encapsulation






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






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






43. Method of establishing and configuring different Network layer protocols






44. WAN stands for?






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






46. Method for encapsulating datagrams over serial links






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






48. Less secure; Passwords are sent in clear text






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






50. Which is true regarding HDLC?
