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 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






2. Physical layer international standard for serial communication






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






4. What does PPP mean?






5. What are the PPP Data Link protocols?






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






7. Write the commands to configure s0 to PPP encapsulation






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






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






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






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






12. 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






13. Bit-oriented Data Link layer protocol






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






15. HDLC stands for what?






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

18. No authentication






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






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






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






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






23. 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






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






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






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






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






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






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






30. What are common Data Link WAN encapsulations?






31. 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






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






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






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






35. Less secure; Passwords are sent in clear text






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






37. 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






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






39. Method for encapsulating datagrams over serial links






40. WAN stands for?






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






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






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






44. Nonproprietary

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






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






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






49. 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






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