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






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






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






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






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






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






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






8. 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






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






10. What are common Data Link WAN encapsulations?






11. Uses MD5 challange/response






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






13. Physical layer international standard for serial communication






14. HDLC stands for what?






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






16. Which is true regarding HDLC?






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






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






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






20. 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






21. Proprietary






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






23. Write the commands to configure s0 to PPP encapsulation






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






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






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






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






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






29. Which PPP protocol provides link establishment?






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






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






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






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






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






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






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






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






39. 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






40. What are the PPP Data Link protocols?






41. 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






42. Method for encapsulating datagrams over serial links






43. Bit-oriented Data Link layer protocol






44. 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






45. What does PPP mean?






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






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






48. One bit at a time over a single channel






49. No authentication






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