The correct answer is A. Define inside and outside interfaces.

Network Address Translation (NAT) is a process in which private IP addresses are translated to public IP addresses, allowing devices on a private network to communicate with devices on a public network such as the Internet.

When configuring NAT, the first step is to define which interfaces are inside (private) and which are outside (public). This is because NAT operates by changing the source IP address of packets as they leave the private network and enter the public network, and then changing the destination IP address of packets as they enter the private network.

Therefore, it is important to define the inside and outside interfaces before proceeding with any other configuration steps. This ensures that the NAT configuration is properly configured and all packets are correctly translated between the private and public networks.

Once the inside and outside interfaces have been defined, the next steps in the NAT configuration process typically involve defining address pools or mapping specific IP addresses, depending on the specific requirements of the network. However, these steps can only be taken after the inside and outside interfaces have been properly identified.
