C. It assigns unique port numbers to differentiate between internal devices
D. It uses a shared pool of public IP addresses for multiple internal devices
B. It dynamically selects an available public IP address from a pool for each outbound connection
What type of NAT enables numerous devices within a private network to utilize a single public IP
address and differentiate between them using unique port numbers?
A. Static NAT (One-to-One NAT)
B. Dynamic NAT (Many-to-Many NAT)
C. Port Address Translation (PAT) / NAT Overload
D. IPv6 Transition NAT

A. Enhanced security due to dynamic mappings
B. Improved network performance with faster packet processing
C. Address reuse to optimize Ip address usage
D. Simplified management without the need for static mappings
C. Address reuse to optimize Ip address usage
In which use case is Dynamic NAT particularly suitable?
A. Hosting multiple websites on a single server
B. Providing Internet access to residential customers in home networks
C. Exposing web servers of publicly accessible services hosted internally
D. Facilitating secure access for remote employees or partners
