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. Nonproprietary






2. 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






3. One bit at a time over a single channel






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






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






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






7. 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






8. 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






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






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






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






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






13. Method of establishing and configuring different Network layer protocols






14. Which is true regarding HDLC?






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






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






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






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






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






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






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






22. What are common Data Link WAN encapsulations?






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






24. HDLC stands for what?






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






26. 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






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






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






29. Which PPP protocol provides link establishment?






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






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






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






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






34. Bit-oriented Data Link layer protocol






35. Physical layer international standard for serial communication






36. 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






37. Uses MD5 challange/response






38. 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)






39. WAN stands for?






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






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






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






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






44. 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






45. What does PPP mean?






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






47. 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






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






49. 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






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