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 point-to-point protocol used on leased lines






2. What does PPP mean?






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






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






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






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






7. What are the PPP Data Link protocols?






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






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






10. 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)






11. Bit-oriented Data Link layer protocol






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






13. Proprietary






14. 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






15. Which is true regarding HDLC?






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






17. Method for encapsulating datagrams over serial links






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






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






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






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






22. WAN stands for?






23. What are common Data Link WAN encapsulations?






24. No authentication






25. 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






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






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






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






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






30. 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






31. Uses MD5 challange/response






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






33. 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






34. 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






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






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






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






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






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






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






42. Nonproprietary






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






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






45. What are the two PPP authentication methods?






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






47. Method of establishing and configuring different Network layer protocols






48. Physical layer international standard for serial communication






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






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