Which device is considered an edge device in a network?

An edge device in a network is defined as a device that serves as a boundary between internal networks and external networks, facilitating communication and data transfer. It typically interacts with sources outside of the organizational network and includes devices such as routers, gateways, and firewalls that manage the entry and exit of data.

When identifying edge devices, it is important to recognize that their primary function is to connect internal resources with external entities, which can include the internet or other third-party networks. This device plays a crucial role in safeguarding the internal network by monitoring and controlling data traffic that crosses the boundary between the internal and external environments.

The other choices represent devices that do not primarily serve this edge function. A server located in the internal network is focused on providing services internally and does not interact directly with external networks. A core switch is designed to manage and direct traffic within the internal network, rather than facilitating connectivity to external sources. An access point is primarily concerned with providing wireless access to the internal network and does not typically handle external interactions in the way an edge device would.
