A company designs its network so that the PCs in the internal network are assigned IP addresses from DHCP servers, and the packets that are sent to the Internet are translated through a NAT-enabled router. What type of NAT enables the router to populate the translation table from a pool of unique public addresses, as the PCs send packets through the router to the Internet?

What type of NAT enables the router to populate the translation table from a pool of unique public addresses, as the PCs send packets through the router to the Internet?

static NAT
dynamic NAT
PAT
ARP

Explanation: ARP is the address resolution protocol and is used to obtain the MAC address of the destination device. Static NAT is a one-to-one mapping between the local and global addresses of a device. PAT, otherwise known as NAT overload, maps multiple private IP addresses to a singular public address or group of addresses. Dynamic NAT uses a pool of public IP addresses and assigns them to requesting devices on a first-come, first-served basis. In the case of dynamic NAT, each device would have a unique public IP address from the pool of public IP addresses as the source IP address in the packets that they send.
