NAT routers and proxy servers must have two IP addresses.
A NAT router can provide Internet access to any client application on the private network.
Proxy servers can cache information they receive from Internet servers.
The Windows Server 2003 operating system includes a proxy server.
A subnet mask indicates whether an IP address is registered or unregistered.
A subnet mask specifies the sizes of the network and host identifiers in an IP address.
A subnet mask is a value assigned by the IANA to uniquely identify a specific network on the Internet.
A subnet mask enables an IP address to be visible from the Internet.
One broadcast domain and one collision domain
One broadcast domain and multiple collision domains
One collision domain and multiple broadcast domains
Several collision domains and several broadcast domains
Preferred DNS server
Excessive broadcast traffic
Excessive number of workstations on the LAN
Excessive number of collision domains
The number of bits in the subnet identifier
The number of bits in the host identifier
The number of bits in the combined subnet and host identifiers
The number of bits in the combined network and subnet identifiers
Preferred DNS server
Because the DHCP server can only receive broadcasts
Because the DHCP client does not yet have an IP address
Because the DHCP server can service requests only from computers on the same LAN
Because the DHCP client must inform all the other clients on the network of its intention to request an IP address
