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. Less secure; Passwords are sent in clear text






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






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






4. Proprietary






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






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






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






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






9. What are common Data Link WAN encapsulations?






10. What does PPP mean?






11. 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






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






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






14. 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)






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






16. WAN stands for?






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






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






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






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






21. Write the command to see the encapsulation method on serial 0 of a Cisco router






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






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






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






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






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






27. No authentication






28. 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






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






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






31. 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






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






33. What are the PPP Data Link protocols?






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






35. Uses MD5 challange/response






36. 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






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






38. One bit at a time over a single 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. If required - either CHAP or PAP can be used to authenticate a link






41. Which PPP protocol provides link establishment?






42. Nonproprietary






43. 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






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






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






46. Bit-oriented Data Link layer protocol






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






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






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






50. What are the two PPP authentication methods?
