Given the following descriptions of layers of the OSI model
1) This layer segments and reassembles data into a data stream
2) This layer manages device addressing tracks the location
of devices on the network and determines the best way to
move data
3) This layer provides the physical transmission of the
data and handles error notification network topology and
flow control.
Choose the statement that lists the layers in the order
described above
A. physical data link network
B. physical session data link
C. data link network transport
D. data link transport network
E. transport network data link
F. transport data link network

The administrator of a comapny 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: router(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? A. The keyword overload is missing from the command. B. The administrator needs to define a NAT pool first. C. An access list must be defined to create static NAT translations. D. The interfaces need to be configured for NAT.
