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






2. Which is true regarding HDLC?






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






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






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






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






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






8. One bit at a time over a single channel






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






10. Nonproprietary






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






12. 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






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






14. Method of establishing and configuring different Network layer protocols






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 of that following is a packet-switching encapsulation?






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






18. Which PPP protocol provides link establishment?






19. No authentication






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






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






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






23. 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)






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






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






26. 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






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






28. 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






29. What are the two PPP authentication methods?






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






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






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






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






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






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






36. HDLC stands for what?






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






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






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






40. Less secure; Passwords are sent in clear text






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






42. Uses MD5 challange/response






43. 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






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






45. Method for encapsulating datagrams over serial links






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






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






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






49. Proprietary






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