4. Q Assuming Ethernet, what type of cable is this? A Crossover

5. Q What type of cable is this? A Coaxial

6. Q What are the most common causes of signal degradation? A Improper Termination Low quality cable or connectors Cable Length exceeding standard

7. Q What is the difference between Symmetrical and Asymmetrical? A S- is even up and down A- is typically slower up and faster down

8. Q What type of cable is this? A Fiber Optic

9. Q What is the name of the connection point in which user equipment connects with ISP equipment? A POP (Point of Presence)

10. Q Assuming Ethernet, what type of cable is this? A Straight Through

11. Q What is the Internet? A A network of networks spread all over the world.

12. Q What is a DSLAM used for? A A DSL Access Multiplexer is the device used by an ISP to accept connections from a consumers DSL modem.

13. Q Why is cable management important? A Presents a neat and organized system Aids in the isolation of cabling problems Protects cables from physical damage

14. Q What type of cable is this? A UTP – Unshielded Twisted Pair

15. Q Just like the high speed connections between switches in a LAN, what are the high speed connections on the Internet called? A Internet Backbone connections.

16. Q What type of Ethernet cable should be used in an environment where EMI is an issue? A STP – Shielded Twisted Pair

17. Q What type of cable is this? A STP – Shielded Twisted Pair

18. Q What type of Ethernet cable should be used indoors when EMI is not a concern? A UTP – Unshielded Twisted Pair

19. Q What term is used to describe how a packet travels across a router as it is sent on to its destination? A Hop(s)

20. Q If someone wanted to test the network path(s) to a specific destination, which Windows command would you use? A Most likely you would use tracert which allows path specific information. One could also use the ping command but the result would have less path information.

22. Q Assuming Ethernet, what type of cable is this? A Straight Through

23. Q Why use patch panels? A Patch panels allow for quick rearrangements of network connections should a failure occur or change become necessary.

24. Q What is a CMTS used for? A A Cable Modem Termination System is the device used by an ISP to accept connections from a consumers cable modem.

25. Q What is the most common type of Ethernet cable for indoor use? A UTP – Unshielded Twisted Pair

26. Q What is the benefit of following cabling standards? A Reliable Data Communications provided all your equipment is working correctly.

27. Q What are the three standards to consider when constructing a network cable? A Connector Type Pinouts for that connector type and cable Maximum length of the cable being used
