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






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






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






4. What are the two PPP authentication methods?






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






6. No authentication






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






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






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






10. Which is true regarding HDLC?






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






12. 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






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






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






15. 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






16. WAN stands for?






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






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






19. HDLC stands for what?






20. 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)






21. Bit-oriented Data Link layer protocol






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






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






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






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






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






27. Less secure; Passwords are sent in clear text






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






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






30. Method for encapsulating datagrams over serial links






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






32. What are common Data Link WAN encapsulations?






33. Proprietary






34. 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

38. Which PPP protocol provides link establishment?






39. 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






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






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






42. Write the commands to configure s0 to PPP encapsulation






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






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






45. What are the PPP Data Link protocols?






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






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

49. What does PPP mean?






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