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






2. 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






3. Less secure; Passwords are sent in clear text






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






5. Proprietary






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






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






8. One bit at a time over a single channel






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






10. No authentication






11. 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)






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






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






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






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






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






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






18. What does PPP mean?






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






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






21. Which is true regarding HDLC?






22. HDLC stands for what?






23. WAN stands for?






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






25. What are common Data Link WAN encapsulations?






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






27. What are the two PPP authentication methods?






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. To connect two DTE networks together through a DCE network






30. 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






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






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






33. Uses MD5 challange/response






34. Method of establishing and configuring different Network layer protocols






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






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






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






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






39. Which PPP protocol provides link establishment?






40. 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






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






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






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






44. Method for encapsulating datagrams over serial links






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






46. 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






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






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






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






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