What is the primary function of an Internet gateway in a network environment?
To assign IP addresses to internal network devices
To increase the security of internal network transactions
To facilitate the transfer of data between a private network and the Internet
To manage intra-network data flow and congestion
An Internet gateway enables networked devices to connect to the Internet by providing a routing path from the local network to the Internet. This function is fundamental in network design to facilitate external communication and access to Internet services. The answer specifying data transfer between a private network and the Internet correctly captures this role. Other options, while related to networking tasks, do not accurately describe the primary function of an Internet gateway.
