Explanation:

Here are the correct answers for matching each NAT type with its descriptor:
* Changes incoming packets sent to a public IP address to different internal IP addresses based on the destination portanswer:Static NAT Explanation: Static NAT maps a public IP address to multiple internal IP addresses based on the port, allowing specific services or applications to be routed to various internal destinations.
* Allows a user on the trusted or optional network to connect to a public server that is on the same physical Firebox interface by its public IP address or domain nameanswer:NAT loopback Explanation: NAT loopback (or NAT reflection) allows internal users to access a public IP address or domain name that resolves to the same local network, making it appear as if they are connecting from outside the network.
* Conserves IP addresses and hides the internal topology of your networkanswer:Dynamic NAT Explanation: Dynamic NAT (or PAT - Port Address Translation) conserves public IP addresses by allowing multiple internal devices to share a single public IP address. This setup is commonly used for outbound internet connections from a private network.
* Changes all incoming and outgoing packets sent from one range of addresses to a different range of addressesanswer:1-to-1 NAT Explanation: 1-to-1 NAT maps each internal IP address to a unique public IP address, providing a one-to-one relationship. This type of NAT is often used for networks that require external access to specific internal resources.
