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






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






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






4. 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






5. Write the commands to configure s0 to PPP encapsulation






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






7. HDLC stands for what?






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






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






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






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






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






13. 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






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






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






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






17. What does PPP mean?






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






19. Proprietary






20. No authentication






21. WAN stands for?






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






23. What are the two PPP authentication methods?






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






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






26. 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






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






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






29. Bit-oriented Data Link layer protocol






30. 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






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






33. Method for encapsulating datagrams over serial links






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






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






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






37. One bit at a time over a single channel






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






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






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






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






42. Nonproprietary






43. Which is true regarding HDLC?






44. Which PPP protocol provides link establishment?






45. Method of establishing and configuring different Network layer protocols






46. 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






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






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






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






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