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






2. HDLC stands for what?






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






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






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






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






7. Method for encapsulating datagrams over serial links






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






9. 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)






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






11. 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






12. What are the two PPP authentication methods?






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






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






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






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






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






18. 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






19. Write the commands to configure s0 to PPP encapsulation






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






21. 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






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






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






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






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






26. 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






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






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






29. Which is true regarding HDLC?






30. Proprietary






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






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






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






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






35. 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






36. Less secure; Passwords are sent in clear text






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






38. One bit at a time over a single channel






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






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






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






42. Method of establishing and configuring different Network layer protocols






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






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






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






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






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






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






49. 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






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