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. 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






2. Less secure; Passwords are sent in clear text






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






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






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






6. 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






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






8. 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






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






10. Bit-oriented Data Link layer protocol






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






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






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






14. 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






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






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






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






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






19. Nonproprietary






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






21. HDLC stands for what?






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






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






24. WAN stands for?






25. What are common Data Link WAN encapsulations?






26. What are the two PPP authentication methods?






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






28. Method for encapsulating datagrams over serial links






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






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






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






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






33. Proprietary






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






35. 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






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






37. Physical layer international standard for serial communication






38. Uses MD5 challange/response






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






40. Which PPP protocol provides link establishment?






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






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






43. 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






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






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






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






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






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






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






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