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






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






3. 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






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






5. What are common Data Link WAN encapsulations?






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






7. 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






8. Less secure; Passwords are sent in clear text






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






10. What are the PPP Data Link protocols?






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






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






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






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






15. Method for encapsulating datagrams over serial links






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






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






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






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






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






21. Nonproprietary






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






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






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






25. Which is true regarding HDLC?






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






27. 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






28. HDLC stands for what?






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






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






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






32. What are the two PPP authentication methods?






33. Bit-oriented Data Link layer protocol






34. Physical layer international standard for serial communication






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






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






38. WAN stands for?






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






40. 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






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






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






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






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






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






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






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






48. What does PPP mean?






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






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