215. You are the administrator of the LAN and you have been reviewing error logs of networking devices and notice a large number of errors associated with several MAC addresses. You suspect that some of the errors are being generated by the routers. Which router commands will allow you to find the ip address associated with each MAC address?

1. show address
2. show arp

2. CDP
3. DHCP
4. SNMP

218. Why does the data communication industry use the layered OSI reference model?

1. None of the above
2. It encourages industry standardization by defining what functions occur at each layer of the modelIt enables equipment from different vendors to use the same electronic components
3. thus saving research and development fundsIt provides a means by which changes in functionality in one layer require changes in other layers

219. What is a process?

1. A Program in High level language kept on disk
2. Contents of main memory
3. None of these

220. The administrator of the network needs to ensure that a web server in their network is accessible from the Internet. Since the network uses private addressing, this requires an IP-to-registered-address mapping. The following command is entered on the router: 1(config)# ip nat inside source static 192.168.2.1 198.18.1.254 After unsuccessful results from a ping to the Internet, the administrator issues the show ip nat translations command and the output is blank. What could be the problem with the NAT configuration for this mapping?

1. The administrator needs to define a NAT pool first.
2. An access list must be defined to create static NAT translations.
3. The keyword overload is missing from the command
4. The interfaces need to be configured for NAT.
