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






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






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






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






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






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






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






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






9. Which is true regarding HDLC?






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






11. Uses MD5 challange/response






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






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






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






15. Physical layer international standard for serial communication






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






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






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






19. WAN stands for?






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






21. Method for encapsulating datagrams over serial links






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






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






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






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






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






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






28. Proprietary






29. Which PPP protocol provides link establishment?






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






31. 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






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






33. Method of establishing and configuring different Network layer protocols






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






35. Bit-oriented Data Link layer protocol






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






38. 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






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






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






41. 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






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






43. Write the commands to configure s0 to PPP encapsulation






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






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






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






47. One bit at a time over a single channel






48. 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)






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