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






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






5. 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






6. Proprietary






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






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






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






10. No authentication






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






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






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






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






15. 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






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






18. 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






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






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






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






22. What does PPP mean?






23. Method for encapsulating datagrams over serial links






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






25. Physical layer international standard for serial communication






26. 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






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






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






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






30. Which is true regarding HDLC?






31. Uses MD5 challange/response






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






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






34. Method of establishing and configuring different Network layer protocols






35. What are the PPP Data Link protocols?






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






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






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






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






40. HDLC stands for what?






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






42. WAN stands for?






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






44. What are the two PPP authentication methods?






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






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






47. Nonproprietary






48. Bit-oriented Data Link layer protocol






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






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