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. 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






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






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






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






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






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






7. What are common Data Link WAN encapsulations?






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






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






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






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






12. 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






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






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






15. 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






16. Less secure; Passwords are sent in clear text






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






18. Physical layer international standard for serial communication






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






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






21. What are the two PPP authentication methods?






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






23. No authentication






24. One bit at a time over a single channel






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






26. What does PPP mean?






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






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






29. Nonproprietary






30. 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






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






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






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






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






35. Which is true regarding HDLC?






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






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






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






39. What are the PPP Data Link protocols?






40. 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






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






42. Uses MD5 challange/response






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






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






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






46. 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






47. Write the commands to configure s0 to PPP encapsulation






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






49. Method of establishing and configuring different Network layer protocols






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