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. 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






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






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






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






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






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






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






8. What are common Data Link WAN encapsulations?






9. 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






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






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






12. No authentication






13. Physical layer international standard for serial communication






14. Which is true regarding HDLC?






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






16. 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






17. 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)






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






19. 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






20. Which PPP protocol provides link establishment?






21. One bit at a time over a single channel






22. Method of establishing and configuring different Network layer protocols






23. What are the PPP Data Link protocols?






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






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






26. Bit-oriented Data Link layer protocol






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






28. Nonproprietary






29. 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






30. 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






31. Less secure; Passwords are sent in clear text






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






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






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






35. What does PPP mean?






36. HDLC stands for what?






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






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






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






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






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






42. 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






43. Proprietary






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






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






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






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






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






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






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