A network administrator needs an internal server to be consistently accessible from external networks using the same public IP address. Which configuration should be implemented to achieve this?
Use dynamic mapping with a pool
Implement Port Address Translation (PAT)
Configure a static mapping
Enable dynamic mapping with overload
Configuring a static mapping creates a permanent one-to-one association between an internal private IP address and a specific public IP address. This ensures that the internal server is always accessible from external networks using the same public IP address. Dynamic mapping with a pool assigns public IP addresses to internal hosts from a pool on a first-come, first-served basis, which doesn't guarantee the same public IP for each session. PAT allows multiple internal hosts to share a single public IP address by using different port numbers but does not provide a consistent public IP for a specific internal host. Dynamic mapping with overload is another term for PAT and also doesn't offer a fixed public IP address for an internal host.
