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 of that following is a packet-switching encapsulation?






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






3. 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






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






5. HDLC stands for what?






6. Physical layer international standard for serial communication






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






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






9. 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






10. 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






11. What are the PPP Data Link protocols?






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






14. 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






15. WAN stands for?






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






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






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






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






20. Which PPP protocol provides link establishment?






21. 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






22. Nonproprietary






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






24. Method of establishing and configuring different Network layer protocols






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






26. Write the commands to configure s0 to PPP encapsulation






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






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






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






30. What are common Data Link WAN encapsulations?






31. No authentication






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






33. Less secure; Passwords are sent in clear text






34. Bit-oriented Data Link layer protocol






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






36. What does PPP mean?






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






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






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






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






41. One bit at a time over a single channel






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






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






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






45. What are the two PPP authentication methods?






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






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






48. 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)






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






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