Ethernet Switches”  Please respond to the following:

• Per the text, a switch is used to interconnect devices together on a network and operates on the Data Link layer of the OSI model. It uses a Media Access Control (MAC) address or physical address to forward frames across the network.

  Imagine that you work as a network administrator for a medium-size company. You have suggested to your boss to upgrade the existing hubs with Cisco Catalysts switches. Provide justification for this action. Include at least three (3) pros and three (3) cons to implementing a switched network.

• As described in the text, network engineers have the abilities to use port security on all LAN switches; unfortunately, many companies do not incorporate this security feature, believing that the internal network is more secure. Provide an argument in favor of using port security to those that believe it is not essential. Provide three (3) justifications for its use.
