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. 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






2. Physical layer international standard for serial communication






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






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






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






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






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






8. Which is true regarding HDLC?






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






10. What are common Data Link WAN encapsulations?






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






12. Nonproprietary






13. What are the PPP Data Link protocols?






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






15. Write the commands to configure s0 to PPP encapsulation






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






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






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






19. 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






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






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






22. Method of establishing and configuring different Network layer protocols






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






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






25. Which PPP protocol provides link establishment?






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






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






28. Less secure; Passwords are sent in clear text






29. 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)






30. 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






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






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






33. Bit-oriented Data Link layer protocol






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






35. Method for encapsulating datagrams over serial links






36. 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






37. Uses MD5 challange/response






38. WAN stands for?






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






40. Proprietary






41. HDLC stands for what?






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






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






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






45. No authentication






46. What does PPP mean?






47. 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






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






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






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