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. Proprietary






2. Write the commands to configure s0 to PPP encapsulation






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






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






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






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






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






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






9. What does PPP mean?






10. 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






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






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






13. What are the PPP Data Link protocols?






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






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






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






17. 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






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






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






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






21. Which is true regarding HDLC?






22. Method of establishing and configuring different Network layer protocols






23. Which PPP protocol provides link establishment?






24. 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






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






26. 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






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






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






29. Method for encapsulating datagrams over serial links






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






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. Uses MD5 challange/response






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






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






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






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






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






39. Physical layer international standard for serial communication






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






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






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






43. Nonproprietary






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






45. What are common Data Link WAN encapsulations?






46. Less secure; Passwords are sent in clear text






47. One bit at a time over a single channel






48. What are the two PPP authentication methods?






49. HDLC stands for what?






50. WAN stands for?
