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 are the two PPP authentication methods?






2. 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






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






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






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






6. 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






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






8. 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






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






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






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






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






13. Bit-oriented Data Link layer protocol






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






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






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






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






18. Less secure; Passwords are sent in clear text






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






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






21. HDLC stands for what?






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






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






24. 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






25. No authentication






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






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






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






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






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






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






32. Uses MD5 challange/response






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






34. Nonproprietary






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






36. Physical layer international standard for serial communication






37. Method of establishing and configuring different Network layer protocols






38. What does PPP mean?






39. What are the PPP Data Link protocols?






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






41. Which PPP protocol provides link establishment?






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






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






44. 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)






45. 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






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






47. What are common Data Link WAN encapsulations?






48. Which is true regarding HDLC?






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






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