Wide Area Netwoking Protocols

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






2. What are the two PPP authentication methods?






3. 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






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






5. Nonproprietary






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






7. Which PPP protocol provides link establishment?






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






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






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






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






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






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






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






15. Less secure; Passwords are sent in clear text






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






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






18. What are common Data Link WAN encapsulations?






19. Proprietary






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






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






22. One bit at a time over a single channel






23. 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






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






25. 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






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






27. Write the commands to configure s0 to PPP encapsulation






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






29. WAN stands for?






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






31. 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






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






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






34. 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)






35. 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






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






37. HDLC stands for what?






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






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






40. No authentication






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






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






44. Physical layer international standard for serial communication






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






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






47. Bit-oriented Data Link layer protocol






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






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






50. Method for encapsulating datagrams over serial links
