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. Nonproprietary






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






3. 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






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






5. 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






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






7. 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






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






9. Physical layer international standard for serial communication






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






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






12. 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






13. What does PPP mean?






14. 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






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






16. Which is true regarding HDLC?






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






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






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






20. One bit at a time over a single channel






21. What are the PPP Data Link protocols?






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






23. Which PPP protocol provides link establishment?






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






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






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 type of port on a router is used for a T1?






28. Write the commands to configure s0 to PPP encapsulation






29. 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)






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






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






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






33. What are the two PPP authentication methods?






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






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






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






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






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






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






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






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






42. Method of establishing and configuring different Network layer protocols






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






44. Bit-oriented Data Link layer protocol






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






46. Proprietary






47. What are common Data Link WAN encapsulations?






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






49. WAN stands for?






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