In the context of Cisco Service Provider Network Core Technologies, a dynamic continuous mapped NAT requires a pool of addresses that can be assigned to internal hosts as they initiate traffic towards the external network. The configuration shown in the exhibit indicates that there is a standard access list named 'Users' permitting the 192.168.1.0/24 network, which suggests that there are potentially up to 254 hosts (given the subnet mask of 255.255.255.0) that could require NAT translation at any given time.
The current NAT pool 'Internet' has a range from 10.10.10.1 to 10.10.10.100 with a netmask of
255.255.255.0, which provides only 100 addresses for translation purposes.
To ensure that there is an address available for each potential host on the inside network (192.168.1.0/24), we need to increase the size of this NAT pool so it can support up to 254 usable addresses (which is one less than the total number due to network and broadcast addresses being unusable). This will allow for each internal user to be dynamically mapped to an external address within this range when accessing resources outside their local network.
