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. 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






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






3. Which is true regarding HDLC?






4. 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






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






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






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






8. Bit-oriented Data Link layer protocol






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






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






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






12. Method for encapsulating datagrams over serial links






13. No authentication






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






15. Proprietary






16. Uses MD5 challange/response






17. Which PPP protocol provides link establishment?






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






19. 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






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






21. WAN stands for?






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






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






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






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






26. What are the two PPP authentication methods?






27. 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






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






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






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






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






32. What are common Data Link WAN encapsulations?






33. One bit at a time over a single channel






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






35. What does PPP mean?






36. Physical layer international standard for serial communication






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






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






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






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






41. 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






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






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






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






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






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






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






48. Nonproprietary






49. 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






50. Method of establishing and configuring different Network layer protocols
