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






2. 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






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






4. Which is true regarding HDLC?






5. Write the commands to configure s0 to PPP encapsulation






6. HDLC stands for what?






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






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






9. 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






10. What are common Data Link WAN encapsulations?






11. 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






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






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






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






15. Physical layer international standard for serial communication






16. Bit-oriented Data Link layer protocol






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






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






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






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






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






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






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






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






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






26. 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






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






28. What does PPP mean?






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






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






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






32. What are the two PPP authentication methods?






33. 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






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






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






36. 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






37. Method for encapsulating datagrams over serial links






38. Uses MD5 challange/response






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






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






41. WAN stands for?






42. 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






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






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






45. 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)






46. What are the PPP Data Link protocols?






47. Method of establishing and configuring different Network layer protocols






48. Nonproprietary






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






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