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. One bit at a time over a single channel






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






3. 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






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






5. 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)






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






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






8. Which is true regarding HDLC?






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






10. What are the PPP Data Link protocols?






11. Bit-oriented Data Link layer protocol






12. 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






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






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






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






16. Physical layer international standard for serial communication






17. 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






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






19. Proprietary






20. Method for encapsulating datagrams over serial links






21. Which PPP protocol provides link establishment?






22. Nonproprietary






23. What are common Data Link WAN encapsulations?






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






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






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






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






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






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






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






31. What does PPP mean?






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






33. Write the commands to configure s0 to PPP encapsulation






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






35. Less secure; Passwords are sent in clear text






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






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






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






39. What are the two PPP authentication methods?






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






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






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






43. Uses MD5 challange/response






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






45. 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






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






47. Method of establishing and configuring different Network layer protocols






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






49. No authentication






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