Refer to the exhibit. Which functionality must be enabled on router A to connect two networks for translating private addresses into "legal" public addresses on a one-for-one basis?

The correct answer is B. NAT. Static NAT (Network Address Translation) performs one-to-one mapping of a private IP address to a public IP address. This is exactly what the question describes-translating private addresses into public addresses on a one-for-one basis. PAT (A), also called NAT Overload, maps…

Explanation

Static NAT (Network Address Translation) performs one-to-one mapping of a private IP address to a public IP address. This is exactly what the question describes-translating private addresses into public addresses on a one-for-one basis. PAT (A), also called NAT Overload, maps many private addresses to a single public IP using different port numbers-a many-to-one relationship, not one-for-one. VLAN (C) is a Layer 2 segmentation technology. GARP (D) is Gratuitous ARP, used for IP conflict detection or failover notification. PPP (E) is a WAN data link protocol. Static NAT is the precise answer for one-for-one address translation.
