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






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






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






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






5. 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






6. Write the commands to configure s0 to PPP encapsulation






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






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






9. What are common Data Link WAN encapsulations?






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






11. Which PPP protocol provides link establishment?






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






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






14. Proprietary






15. WAN stands for?






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






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






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






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






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






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






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






23. One bit at a time over a single channel






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






25. Less secure; Passwords are sent in clear text






26. What are the two PPP authentication methods?






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






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






29. 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






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






31. Uses MD5 challange/response






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






33. Which is true regarding HDLC?






34. 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






35. Nonproprietary






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






37. HDLC stands for what?






38. 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)






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






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






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






42. Physical layer international standard for serial communication






43. What does PPP mean?






44. Bit-oriented Data Link layer protocol






45. 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






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






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






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






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






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