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






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






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






4. Method for encapsulating datagrams over serial links






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






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






7. 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






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






9. What are common Data Link WAN encapsulations?






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






11. What does PPP mean?






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






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






15. Write the commands to configure s0 to PPP encapsulation






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






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






18. Proprietary






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






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






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






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






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






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






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






26. Which PPP protocol provides link establishment?






27. No authentication






28. 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






29. Which is true regarding HDLC?






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






31. HDLC stands for what?






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






33. What are the PPP Data Link protocols?






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






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






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






37. Physical layer international standard for serial communication






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






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






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






41. 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






42. 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)






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






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






45. Uses MD5 challange/response






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






47. What are the two PPP authentication methods?






48. Nonproprietary






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






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