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






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






3. 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






4. Physical layer international standard for serial communication






5. What are common Data Link WAN encapsulations?






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






7. Bit-oriented Data Link layer protocol






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






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






10. Uses MD5 challange/response






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






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






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






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






16. WAN stands for?






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






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






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






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






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






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






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






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






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






26. 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






27. Which is true regarding HDLC?






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






29. HDLC stands for what?






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

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






33. Method of establishing and configuring different Network layer protocols






34. One bit at a time over a single channel






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






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






37. Method for encapsulating datagrams over serial links






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






39. Write the commands to configure s0 to PPP encapsulation






40. Nonproprietary






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






42. Less secure; Passwords are sent in clear text






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






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






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






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






47. Which PPP protocol provides link establishment?






48. What does PPP mean?






49. 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






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