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






2. 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






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






4. Which is true regarding HDLC?






5. What are common Data Link WAN encapsulations?






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






7. Write the commands to configure s0 to PPP encapsulation






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






9. Bit-oriented Data Link layer protocol






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






11. 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)






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






13. What does PPP mean?






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






15. No authentication






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






17. Which PPP protocol provides link establishment?






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






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






20. HDLC stands for what?






21. Proprietary






22. WAN stands for?






23. Less secure; Passwords are sent in clear text






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






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






26. 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






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






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






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






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






32. What are the two PPP authentication methods?






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






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






35. Method for encapsulating datagrams over serial links






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






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






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






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






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






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






42. Uses MD5 challange/response






43. 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






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






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






46. Physical layer international standard for serial communication






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






48. 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






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






50. Method of establishing and configuring different Network layer protocols
