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






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






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






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






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






6. 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






7. HDLC stands for what?






8. Nonproprietary






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






10. What are the two PPP authentication methods?






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






12. What does PPP mean?






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






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






15. Bit-oriented Data Link layer protocol






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






17. Uses MD5 challange/response






18. 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)






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






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






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






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






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






24. Proprietary






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






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






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






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






29. Less secure; Passwords are sent in clear text






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






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






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






33. Which PPP protocol provides link establishment?






34. 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






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






36. Method for encapsulating datagrams over serial links






37. Physical layer international standard for serial communication






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






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






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






41. What are the PPP Data Link protocols?






42. 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






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






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






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






46. One bit at a time over a single channel






47. Network Control Protocol (NCP) is used to allow multiple Network layer protocols (routed protocols) to be used on a point-to-point connection






48. 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






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






50. 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
