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






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






3. Less secure; Passwords are sent in clear text






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






5. 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






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 are considered WAN connection types? (Choose three.)






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






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






10. 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






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






12. Proprietary






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






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






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






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






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






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






20. What are common Data Link WAN encapsulations?






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






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






23. 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






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






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






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






27. Uses MD5 challange/response






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






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






30. What are the two PPP authentication methods?






31. Nonproprietary






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






33. WAN stands for?






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






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






36. What are the PPP Data Link protocols?






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






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






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






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






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






42. HDLC stands for what?






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






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






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






46. Which PPP protocol provides link establishment?






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






48. 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






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






50. Method for encapsulating datagrams over serial links
