When configuring source NAT with no-pat, which statement is true?

When configuring source NAT with no-pat (Network Address Translation with no Port Address Translation), the primary function is to translate the source IP address of the packets traveling from a private network to a public network while keeping the original source port the same. This means that only the source IP address is altered to reflect an address from a designated public address space.

In this context, no-pat means that while the source address of outgoing packets is modified, the port numbers remain intact, allowing the destination to respond to the originating device at the same port. This approach is often used when there is a need to conserve IP addresses or when managing multiple devices behind a single public address without the need for port mapping.

The other options presented do not accurately describe the behavior of source NAT with no-pat. For example, translating only the destination IP address, or translating both the source IP address and port number, or the destination IP address and port number, does not align with the principles of source NAT configured specifically with no-pat, which focuses solely on translating the source IP address.
