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






2. 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






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






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






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






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






7. What are common Data Link WAN encapsulations?






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






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






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






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






12. What does PPP mean?






13. 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)






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






15. What are the two PPP authentication methods?






16. 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






17. Bit-oriented Data Link layer protocol






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






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






20. Proprietary






21. Physical layer international standard for serial communication






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






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






24. One bit at a time over a single channel






25. 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






26. Uses MD5 challange/response






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






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






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






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






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






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






33. 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






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






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






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






37. Method for encapsulating datagrams over serial links






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






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






40. Which PPP protocol provides link establishment?






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






42. No authentication






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






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






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






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






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






48. Write the commands to configure s0 to PPP encapsulation






49. What are the PPP Data Link protocols?






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