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






2. Which PPP protocol provides link establishment?






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






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






5. What are the two PPP authentication methods?






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






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






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






9. What does PPP mean?






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






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






12. 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






13. 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






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






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






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






17. Method of establishing and configuring different Network layer protocols






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






19. Write the commands to configure s0 to PPP encapsulation






20. What are common Data Link WAN encapsulations?






21. 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)






22. Nonproprietary






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






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






25. Method for encapsulating datagrams over serial links






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






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






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






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






30. No authentication






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






32. Bit-oriented Data Link layer protocol






33. 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






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






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






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






37. 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






38. WAN stands for?






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






40. What are the PPP Data Link protocols?






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






42. 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






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






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






46. 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






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






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






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






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