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. Nonproprietary






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






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






4. 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






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






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






7. What are the two PPP authentication methods?






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






9. Method of establishing and configuring different Network layer protocols






10. 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






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






12. What are common Data Link WAN encapsulations?






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






14. Less secure; Passwords are sent in clear text






15. Uses MD5 challange/response






16. Proprietary






17. Bit-oriented Data Link layer protocol






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






19. What are the PPP Data Link protocols?






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






21. HDLC stands for what?






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






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






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






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






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






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






28. 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






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






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






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






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






33. 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






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






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






36. Physical layer international standard for serial communication






37. One bit at a time over a single channel






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






39. Write the commands to configure s0 to PPP encapsulation






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






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






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






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






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






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






46. Write the command to see the encapsulation method on serial 0 of a Cisco router






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






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






49. What does PPP mean?






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