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. Method for encapsulating datagrams over serial links






2. HDLC stands for what?






3. What are the PPP Data Link protocols?






4. Uses MD5 challange/response






5. What does PPP mean?






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






7. 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






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






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






10. 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






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






12. Write the commands to configure s0 to PPP encapsulation






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






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






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






16. 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






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






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






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






20. WAN stands for?






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






22. What are the two PPP authentication methods?






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






24. Physical layer international standard for serial communication






25. 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






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






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






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






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






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






31. Which PPP protocol provides link establishment?






32. Method of establishing and configuring different Network layer protocols






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






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






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






36. Proprietary






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






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






39. 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






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






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






42. Nonproprietary






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






44. 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






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






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






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






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






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






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