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






2. WAN stands for?






3. Method for encapsulating datagrams over serial links






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






5. No authentication






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






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






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






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






10. Physical layer international standard for serial communication






11. What does PPP mean?






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






13. Bit-oriented Data Link layer protocol






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






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






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






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






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






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






20. Nonproprietary






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






22. Proprietary






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






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






25. Less secure; Passwords are sent in clear text






26. 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)






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






28. 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






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






30. HDLC stands for what?






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






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






33. Write the commands to configure s0 to PPP encapsulation






34. Which is true regarding HDLC?






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






36. 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






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






38. What are common Data Link WAN encapsulations?






39. What are the two PPP authentication methods?






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






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






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






43. 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






44. Method of establishing and configuring different Network layer protocols






45. 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






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






47. One bit at a time over a single channel






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






49. What are the PPP Data Link protocols?






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