A company wants internal devices with private addresses to access the Internet through a public address. Which Network Address Translation (NAT) function matches this need?

### Why this is right Source NAT changes the source address of outgoing traffic, commonly translating private addresses to a public address. This is the usual function for internal devices accessing the Internet through an edge firewall. ### The concept NAT changes an address as traffic passes through a network device. Source NAT changes the source address. Destination NAT changes the destination address and is commonly used to forward an external connection to a private server. Neither type of NAT is a security permission by itself. ### The other options - **B. Destination NAT**: this maps an external destination toward an internal destination, often for inbound access to a server. - **C. Implicit deny**: this is a firewall policy behavior, not an address translation function. - **D. Application identification**: this is an additional security capability, not address translation. ### Terms - **NAT**: Network Address Translation. A method of changing network addresses. - **Source NAT**: Translation that changes the source address of traffic. ### Remember Outgoing private-to-public translation is source NAT.
