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. 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






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






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






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






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






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






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






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






9. HDLC stands for what?






10. Which PPP protocol provides link establishment?






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






12. Proprietary






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






14. 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






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






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






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






18. Write the commands to configure s0 to PPP encapsulation






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






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






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






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






23. Which is true regarding HDLC?






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






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






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






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






28. Method for encapsulating datagrams over serial links






29. 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






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






31. WAN stands for?






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






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






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






35. Method of establishing and configuring different Network layer protocols






36. 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






37. What are the two PPP authentication methods?






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






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






40. Includes the area from the CSU/DSU - through the provider's wiring and switches - all the way to the CSU/DSU at the other end; provides clocking to the DTE-connected interface (the router's serial interface)






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






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






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






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






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






46. What does PPP mean?






47. 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






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






49. Less secure; Passwords are sent in clear text






50. No authentication
