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. To connect two DTE networks together through a DCE network






2. 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






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






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






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






6. Nonproprietary






7. What are the two PPP authentication methods?






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






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






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






11. WAN stands for?






12. 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






13. 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






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






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






16. Bit-oriented Data Link layer protocol






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






18. Physical layer international standard for serial communication






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






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






21. To transport layer 3 packets across a Data Link layer point-to-point link






22. Write the commands to configure s0 to PPP encapsulation






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






24. 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






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






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






27. Which is true regarding HDLC?






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






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






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






31. Less secure; Passwords are sent in clear text






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






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






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






35. What are common Data Link WAN encapsulations?






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






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






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






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






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






41. 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






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






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






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






45. No authentication






46. Proprietary






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






48. 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






49. What does PPP mean?






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