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






2. 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






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






4. Uses MD5 challange/response






5. 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






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






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






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






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






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






11. Physical layer international standard for serial communication






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






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






14. 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)






15. Which is true regarding HDLC?






16. 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






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






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






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






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






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






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






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






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






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






26. Write the commands to configure s0 to PPP encapsulation






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






28. What does PPP mean?






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






30. 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






31. What are the PPP Data Link protocols?






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






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






34. Less secure; Passwords are sent in clear text






35. Method for encapsulating datagrams over serial links






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






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






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






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






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






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






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






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






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






45. Nonproprietary






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






47. What are common Data Link WAN encapsulations?






48. 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






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






50. WAN stands for?
