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 reason why the serial link between the Corp router and the Remote router will not come up?






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






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






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






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






6. 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






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






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






9. Write the commands to configure s0 to PPP encapsulation






10. One bit at a time over a single channel






11. What does PPP mean?






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






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






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






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






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






17. Uses MD5 challange/response






18. Which is true regarding HDLC?






19. What are the PPP Data Link protocols?






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






21. Which PPP protocol provides link establishment?






22. Method of establishing and configuring different Network layer protocols






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






24. Nonproprietary






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 type of port on a router is used for a T1?






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






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






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






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






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






32. 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






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






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






35. 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






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






37. HDLC stands for what?






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






39. What are common Data Link WAN encapsulations?






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






41. A connection-oriented protocol at the Data Link layer for use with X.25; causes a tremendous amount of overhead because of its strict time-out and windowing techniques; can also be used as a simple data link transport






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






43. Bit-oriented Data Link layer protocol






44. 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






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






46. Less secure; Passwords are sent in clear text






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






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






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






50. No authentication
