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






2. 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






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






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






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






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






7. Bit-oriented Data Link layer protocol






8. What are the PPP Data Link protocols?






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






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






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






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






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






14. 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






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






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






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






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






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






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






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






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






24. 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






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






26. What are the two PPP authentication methods?






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






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






29. Uses MD5 challange/response






30. Method for encapsulating datagrams over serial links






31. Which is true regarding HDLC?






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






33. Write the commands to configure s0 to PPP encapsulation






34. 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






35. Less secure; Passwords are sent in clear text






36. 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






37. What are common Data Link WAN encapsulations?






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






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






40. 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






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






42. No authentication






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






44. What does PPP mean?






45. One bit at a time over a single channel






46. HDLC stands for what?






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






48. 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






49. Proprietary






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