A multinational corporation is restructuring its network to optimize internal and external communications. The IT team must implement an IP addressing strategy using both private and public IP addresses, considering NAT and global IP allocation policies. Which scenario correctly demonstrates the advanced use and management of these addresses?

Options :

A : Assign private IPs for all branches and use dynamic NAT to map each to a unique public IP for external communication.

B : Allocate public IPs to all internal devices, avoiding NAT and ensuring global addresses for direct communication.

C : Use private IPs within branches, with a centralized NAT gateway at each branch translating to a smaller pool of public IPs for internet access.right

D : Mix private and public IPs within the same subnet, allowing flexible internal and external communication without NAT.

Answer: C
