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






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






5. Uses MD5 challange/response






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






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






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






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






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






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






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






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






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






15. 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






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






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






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






19. Which PPP protocol provides link establishment?






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






21. Method for encapsulating datagrams over serial links






22. Which is true regarding HDLC?






23. 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






24. What does PPP mean?






25. 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






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






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






28. 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






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






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






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






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






33. What are the two PPP authentication methods?






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






35. Proprietary






36. What are common Data Link WAN encapsulations?






37. Which type of port on a router is used for a T1?






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






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






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






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






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






43. 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






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






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






46. No authentication






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






48. 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






49. Bit-oriented Data Link layer protocol






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